Roughly twenty-six thousand years ago, the Earth entered the final phase of the last ice age, when more than 30 million square kilometres of the northern continents were mantled by ice. Sea level dropped by over a hundred metres, continents expanded, and the atmosphere became drier and dustier. When the climate warmed, that frozen water returned to the ocean basins, transforming every river and shoreline on the planet. Understanding the magnitude and tempo of this transition is fundamental to reconstructing the landscapes that Holocene societies inherited. (The Post-Glacial Flooding Hypothesis)
The scientific history of sea-level research stretches back more than a century. Fairbridge (1961) first proposed that global “drowned terraces” recorded former sea levels. Oxygen-isotope analysis later provided a direct measure of global ice volume (Shackleton & Opdyke 1973; Chappell & Shackleton 1986). By the 1990s, uranium-thorium dating of coral reefs (Bard et al., 1990) and glacio-isostatic models (Lambeck & Chappell 2001) produced continuous global sea-level curves for the late Quaternary. Satellite altimetry and GRACE gravimetry now track present-day mass exchange between ice sheets and oceans with millimetre precision (Watkins et al., 2015; Cazenave et al., 2018).
These cumulative datasets reveal that the transformation from the Last Glacial Maximum (LGM) to the modern interglacial was neither instantaneous nor globally uniform. The following sections examine the evidence for the magnitude of the LGM, the deglacial rise in sea level, and the feedbacks that coupled ice, ocean, and atmosphere into a single dynamic system.
The Post-Glacial Flooding Hypothesis
2. The Last Glacial Maximum
The LGM, dated between ~26 000 and 19 000 years BP, represents the maximum combined extent of Northern Hemisphere ice sheets. Reconstructions by Ehlers et al. (2018) show the Laurentide Ice Sheet extending south of the Great Lakes, the Fennoscandian complex covering Scandinavia, northern Britain, and the Baltic, and separate domes over the Barents and Kara Seas. In the Southern Hemisphere, the Patagonian, New Zealand, and Antarctic ice sheets expanded simultaneously. Global mean air temperature was about 5–6 °C lower than today (Tierney et al., 2020).
Cosmogenic-nuclide dating of moraines indicates near-synchronous maxima in both hemispheres within 1–2 kyr (Balco et al., 2009). Ice cores from Antarctica record atmospheric CO₂ concentrations of only ~190 ppm, the lowest of the last 800 kyr (Lüthi et al., 2008). The increased planetary albedo and reduced greenhouse forcing locked the Earth into a radiative imbalance until orbital precession increased summer insolation at high latitudes around 21 ka BP, initiating melting.
Sea level at the LGM stood 134 ± 5 m below present (Rohling et al., 2009; Lambeck et al., 2014), implying an extra ~52 × 10⁶ km³ of continental ice—roughly triple modern Antarctic volume. The load depressed the lithosphere by up to a kilometre and generated a peripheral forebulge hundreds of kilometres wide. When deglaciation began, these distortions created regional variations in relative sea level (RSL) of tens of metres—a problem that still complicates correlation between sites.
The Post-Glacial Flooding Hypothesis
3. Quantifying Global Ice and Sea-Level Change
High-resolution oxygen-isotope records from the Red Sea (Rohling et al., 2009) and global benthic stacks (Lisiecki & Raymo, 2005) define the eustatic component of sea-level change. Grant et al. (2014) extended the Red Sea curve to 500 kyr BP and confirmed an approximately linear relation between δ¹⁸O and global mean sea level within ±140 m. Combined with coral-reef U/Th dates (Peltier & Fairbanks 2006) and glacio-isostatic modelling (ICE-6G v2; Peltier et al., 2015), these data yield the following deglacial sequence:
The Post-Glacial Flooding Hypothesis
Stable minimum (26–19 ka) — Sea level constant near −130 m; ice volume at maximum.
Deglacial rise (19–7 ka) — Global mean increase ~120 m; average rate ~1.2 cm yr⁻¹.
Waelbroeck et al. (2019) and Gowan et al. (2021) further improved resolution, showing that roughly 70% of the total rise occurred before 10 ka BP and that rates exceeded 4 cm yr⁻¹ during short meltwater pulses. These figures quantify the pace of global hydrological reorganisation that followed the LGM.
The Post-Glacial Flooding Hypothesis
4. Meltwater Pulses and Deglacial Chronology
Superimposed on the long-term trend are several abrupt accelerations known as Meltwater Pulses (MWPs). MWP-1A (14.6–14.3 ka BP) raised global sea level by 14–18 m in < 400 years (Deschamps et al., 2012). Coral cores from Tahiti and Barbados capture the event as a distinct change in growth depth and isotope composition. MWP-1B, centred near 11.5 ka BP, added another 6–10 m (Liu et al., 2019). A later, smaller pulse (~8.2 ka BP) corresponded to catastrophic drainage of pro-glacial Lake Agassiz into the North Atlantic (Teller et al., 2002).
Numerical models (Gregoire et al., 2012) indicate that collapse of the Laurentide ice saddle triggered MWP-1A, releasing freshwater at ~0.3 Sverdrups—enough to disrupt the Atlantic Meridional Overturning Circulation (AMOC) and cause short-lived cooling across the Northern Hemisphere (Liu et al., 2009). Geomorphic evidence of megafloods, such as the Missoula outburst channels in North America (Bretz 1969; Baker 2013), provides analogues for the required discharge scale.
MWPs demonstrate that deglaciation was a series of threshold events rather than a steady retreat. The timing of pulses aligns closely with abrupt climatic shifts seen in Greenland ice cores (NGRIP Members 2004), underscoring the tight coupling between ice dynamics and global climate.
5. Isostatic Rebound and Crustal Adjustment
Once surface loads were removed, the lithosphere began to rebound. The process is governed by viscoelastic relaxation of the mantle with characteristic times of 1–5 kyr (Milne et al., 2006). Modern GPS and tide-gauge data show uplift of 10 mm yr⁻¹ in central Fennoscandia and subsidence of 1–2 mm yr⁻¹ in southern England and the Netherlands—the collapsing forebulge. Modelling (Lambeck et al., 2014; Peltier et al., 2015) reproduces these patterns when mantle viscosities of 3–5 × 10²¹ Pa s are used.
Rebound created ephemeral basins along glacial margins where meltwater ponded before marine incursion. The Baltic Ice Lake and the Champlain Sea are classic examples, forming as differential uplift temporarily dammed drainage routes (Saarnisto & Salonen 1995; Parent & Occhietti 1999). Many present-day estuaries owe their origins to these basins. Sediment cores from the Humber, Thames, and Rhine estuaries contain alternating freshwater and brackish layers that track the balance between isostasy and eustasy (Shennan et al., 2018).
The Post-Glacial Flooding Hypothesis
6. The Rebirth of the Oceans
Between 19 ka and 7 ka BP, the oceans absorbed roughly 4.5 × 10⁸ km³ of meltwater, raising mean sea level by ~120 m. Coral records from Tahiti, Huon Peninsula, and the Sunda Shelf show a remarkably consistent transgression curve (Deschamps et al., 2012; Hanebuth et al., 2000). By 7 ka BP, sea level stabilised within a few metres of the modern datum.
The redistribution of this mass altered Earth’s rotation and gravitational field, increasing the length of day by 0.5 milliseconds (Mitrovica & Munk 2003) and displacing the geoid by several decimetres. More tangibly, flooding of continental shelves expanded shallow-marine habitats and enhanced nutrient exchange between land and sea, fuelling mid-Holocene marine productivity (Haug et al., 2001). The creation of new estuarine and lagoonal systems also provided nursery grounds for species that later became critical to human subsistence.
7. Climate Feedbacks During Deglaciation
Ice-core and modelling studies reveal that the deglacial rise in greenhouse gases both responded to and accelerated warming. CO₂ increased from 190 ppm at the LGM to 270 ppm by 11 ka BP (Lüthi et al., 2008). Methane doubled from 350 to 700 ppb (Loulergue et al., 2008). The combined radiative forcing of ~2.5 W m⁻² produced a global temperature increase of ~4 °C (IPCC AR6 2021). Shakun et al. (2012) demonstrated that Antarctic warming led the CO₂ rise by several centuries, implying that oceanic outgassing initiated the feedback loop.
Freshwater discharges into the North Atlantic weakened the AMOC and triggered millennial-scale climate reversals. The Younger Dryas (12.9–11.7 ka BP) involved a 5–7 °C drop in Greenland temperatures followed by rapid recovery within a few decades (Severinghaus et al., 1998). Numerical experiments show that such shifts require freshwater fluxes of 0.05–0.1 Sverdrups (Liu et al., 2009). Once meltwater routing shifted southward and AMOC strength recovered, interglacial stability was achieved.
The Post-Glacial Flooding Hypothesis
8. The Transformation of North-West Europe
Retreat of the British–Irish Ice Sheet began near 22 ka BP and concluded by 15 ka BP (Clark et al., 2012). Deglaciation exposed outwash plains and periglacial lakes that evolved into estuaries and wetlands as sea level rose. Seismic and core evidence from the southern North Sea shows basal peats overlain by brackish and marine sediments between 9 and 8 ka BP (Hijma & Cohen 2011). These sequences chart the drowning of Doggerland—a vast lowland linking Britain to Europe. Pollen and macrofossil data indicate temperate woodland colonisation prior to submergence (Gaffney et al., 2009).
Regional RSL curves diverge sharply due to GIA: western Scotland has risen > 40 m since 10 ka, while southern England has subsided by ~10 m (Bradley et al., 2020). Raised beaches in the north and submerged forests in the south reflect this differential motion. In the English Channel, fluvial erosion during early deglaciation carved the “Channel River,” later flooded by 8 ka (Mellett et al., 2013). Similar sequences occur along the Irish and Danish coasts, documenting the progressive marine transgression of northwest Europe.
The Post-Glacial Flooding Hypothesis
9. Towards a Global–Regional Synthesis
By combining isotopic, coral, and geodetic datasets, modern reconstructions achieve decimetre precision for Holocene sea level (Gowan et al., 2021). Three principles emerge:
Proportionality — Sea level and global ice volume vary linearly during deglaciation.
Pulsation — Superimposed meltwater pulses mark thresholds in ice-sheet stability.
Regionality — Local deviations result from isostasy, tectonics, and sediment compaction.
Shennan et al. (2018) synthesised over 500 Holocene RSL indicators for the British Isles, demonstrating that once GIA corrections are applied, regional curves converge on the global mean within analytical error. These findings provide a quantitative baseline for analysing river-terrace altitudes and groundwater histories in later chapters.
Equally important, comparison with modern sea-level observations highlights the extraordinary pace of contemporary change. Satellite altimetry records a mean rise of 3.4 ± 0.4 mm yr⁻¹ since 1993 (Cazenave et al., 2018)—an order of magnitude faster than the late-Holocene background rate (Kopp et al., 2016). The processes that ended the last ice age therefore remain relevant to current climate dynamics.
The Post-Glacial Flooding Hypothesis
10. Conclusion
The end of the last ice age was a planetary event in which ice, water, and rock interacted on colossal scales. Between 26 ka and 7 ka BP, sea level rose more than 120 m, ice sheets vanished from most temperate latitudes, and the hydrological cycle intensified. The evidence—oxygen-isotope curves, coral terraces, basal peats, and glacio-isostatic models—forms a coherent narrative of gradual yet punctuated change.
These quantitative reconstructions define the environmental backdrop for all Holocene landscapes. They also establish a principle crucial to later chapters: that elevation within fluvial and coastal systems encodes time, because each terrace or peat horizon corresponds to a known fraction of global ice volume. The following chapter therefore turns from global physics to the mathematical description of flooding itself—the equations that translate ice-volume change into measurable hydrological response.
Plain-Language Conclusion
The ice age was like the planet putting a huge amount of the world’s water into giant freezers on land. When those freezers started to melt:
All that stored water went back into the oceans.
The seas rose by about 120 metres.
The weight of the ice came off the land, so some places bounced up, others sagged down.
Scientists can see this story in:
tiny shells on the sea floor,
old coral reefs now sitting at the “wrong” depths,
layers of mud and peat around coasts.
Put simply:
We froze the oceans on land, then poured them back in. The combination of rising seas and bouncing crust rearranged coastlines everywhere, and we can measure it.

My blog delves into the fascinating mysteries of prehistoric Britain, challenging conventional narratives and offering fresh perspectives grounded in cutting-edge research, particularly LiDAR technology. I invite you to explore some key areas of my research. For example, the Wansdyke, often cited as a defensive structure, is re-examined in light of new evidence. I’ve presented my findings in my blog post Wansdyke: A British Frontier Wall – ‘Debunked’, and a Wansdyke LiDAR Flyover video further visualises my conclusions.
My work also often challenges established archaeological dogma. I argue that many sites, such as Hambledon Hill, commonly identified as Iron Age hillforts, are not what they seem. My posts Lidar Investigation Hambledon Hill – NOT an ‘Iron Age Fort’ and Unmasking the “Iron Age Hillfort” Myth explore these ideas in detail and offer an alternative view. Similarly, sites like Cissbury Ring and White Sheet Camp receive re-evaluations based on LiDAR analysis in my posts “Lidar Investigation Cissbury Ring through time”and “Lidar Investigation White Sheet Camp,“ revealing fascinating insights into their true purpose. I have also examined South Cadbury Castle, often linked to the mythical Camelot56.
My research also extends to ancient water management, including the role of canals and other linear earthworks. I have discussed the true origins of Car Dyke in multiple posts, including Car Dyke – ABC News Podcast and Lidar Investigation Car Dyke – North Section, which suggest a Mesolithic origin 2357. I also explore the misidentification of Roman aqueducts, as seen in my posts on the Great Chesters (Roman) Aqueduct. My research has also been greatly informed by my post-glacial flooding hypothesis, which has helped explain landscape transformations over time. I have discussed this hypothesis in several posts, including AI now supports my Post-Glacial Flooding Hypothesis and Exploring Britain’s Flooded Past: A Personal Journey

Hollows, Sunken Lanes and Palaeochannels – these landscape features have been the product of mythology throughout history.
Introduction
Standing on the worn, weathered path of a holloway, enveloped by the towering earthen walls on either side, I often contemplate the origins of these enigmatic features. As a wanderer drawn to these ancient pathways, I’ve always been fascinated by the layers of history and mystery that seem to permeate the very soil beneath my feet. Holloways, these sunken roads carved into the landscape, carry with them the aura of countless stories, but their formation captivates my curiosity the most. (Hollows, Sunken Lanes and Palaeochannels)
Far too high to be foot treaded by traffic or carts – probably quarrying
Hollows
Holloways are found primarily in the rural landscapes of Europe, with many prominent examples in the UK. These paths are often etched into the bedrock, composed of resilient materials like sandstone and chalk. Commonly held beliefs suggest that these sunken roads were formed by the relentless tread of human and animal traffic over centuries. The romantic notion is appealing, conjuring images of medieval pilgrims, bustling traders, and local villagers using these routes daily, gradually wearing down the earth. However, as I walk these secluded paths, far from any major urban centre, the narrative begins to feel a bit disjointed.
The solitude of these holloways contradicts the idea of heavy, consistent traffic. Many of these paths lie hidden, nestled away from the bustling life of cities and even small towns. They weave through the countryside, often known only to locals and to those few who seek them out for their historic and aesthetic appeal. This observation leads me to question: Could human activity alone have really caused such significant erosion in such durable geological materials?
Chinnock Hollow – Yeovil
Case Study – Chinnock Hollow
My scepticism grows as I consider the geological and environmental factors at play. It seems more plausible that these paths are not solely the product of human endeavour but also, and perhaps more so, of natural processes. Indeed, some of the holloways show signs of being man-made, likely the result of historical quarrying activities. These paths are narrower, carved with a precision that suggests deliberate human intervention, perhaps as part of resource extraction practices in ancient times. The straight, purposeful lines contrast with the more organic shapes of other holloways. (Hollows, Sunken Lanes and Palaeochannels)
More intriguing to me are the holloways with rounded, sinuous forms, which suggest the sculpting hand of natural forces. The hypothesis that resonates with me involves the actions of water—powerful, persistent water. During the last ice age, melting glaciers could have dramatically altered the landscape, with meltwater raising water tables and creating new streams and rivers. Over millennia, these waterways could have carved out the initial shapes of what would become holloways, with subsequent water flow deepening and defining their courses. As the climate warmed and the ice retreated, these temporary torrents may have dried up, leaving behind the hollowed-out paths we see today.
On the old OS map, it looks like it might be associated with town footfall?
This theory aligns with my observations of the Holloways’ locations and forms. Those shaped by water exhibit a rounded, undulating profile that mirrors the natural flow of streams and rivers, a stark contrast to the angular, deliberate cuts of man-made paths. Moreover, the presence of dried-up springs and altered watercourses in the vicinity of many holloways supports this idea, suggesting a historical environmental context far different from today’s. (Hollows, Sunken Lanes and Palaeochannels)
Yet, despite these insights, the allure of the mystical and the mythical still clings to these ancient roads. There is a certain romanticism in imagining the holloways as arteries of the old world, teeming with life and stories. But as much as I appreciate the charm of these tales, my quest for understanding leans on science. The true story of the Holloways, I believe, lies at the intersection of human history and natural history—a narrative crafted not just by the footsteps of our ancestors but by the powerful, sculpting hands of the earth itself.
Chinnock Hollow on LiDAR clearly shows it is a natural Palaeochannel and not man-made
It’s clear that more comprehensive geological and historical research is needed to fully unravel the origins of these fascinating features. Geologists and historians together could shed light on how these paths were formed and evolved over time, providing a clearer picture that marries the mythical with the empirical. Such investigations could not only satisfy the curiosity of those like myself but also enhance our appreciation of how deeply intertwined our history is with the natural world. As I continue to explore these paths, the desire for knowledge only grows, driving me to advocate for deeper studies that might finally illuminate the full story of these hollowed roads, etched so indelibly into the landscape.

Site Investigation Protocol: Advanced LiDAR Interpretation for Prehistoric Landscape Features
1. Protocol Scope and Strategic Objective
This protocol mandates an immediate strategic departure from the “military-defensive” fantasies that have dominated British archaeology for over a century. We are moving toward a rigorous “hydrological-prehistoric” framework. Traditional interpretations—often little more than “archaeological pulp fiction”—reflexively categorise every ditch as a defensive frontier and every hollow as a product of medieval foot traffic. Such narratives ignore the fundamental geomorphology of the post-glacial British landscape. Accurate classification of dykes, holloways, and earthworks is not a matter of historical debate; it is a matter of geospatial science.
The core objective of this protocol is to deploy high-resolution LiDAR as the primary diagnostic instrument to identify prehistoric canals and palaeochannels. By stripping away the interference of modern agricultural scarring and Holocene vegetation, we expose the “ground truth” of the prehistoric surface. This protocol utilises the “Post-Glacial Flooding Hypothesis” to reclassify features previously shrouded in myth, providing a technical roadmap for identifying a sophisticated maritime infrastructure that once connected Britain to the European continent.
2. Theoretical Framework: The Post-Glacial Hydrological Paradigm
The “Post-Glacial Flooding Hypothesis” is the analytical lens through which all features must be viewed. This paradigm recognises that the primary architects of the British landscape were not Iron Age warriors or Saxon labourers, but the catastrophic volumes of meltwater and significantly raised water tables following the last glacial maximum. Traditional “Ivory Tower” archaeology suffers from a fundamental failure to account for these hydrological forces, leading to the systemic misidentification of natural watercourses as “man-made” sunken roads.
Environmental Drivers of Landscape Formation
Investigators must account for the following drivers in every site assessment:
Meltwater Torrents: Persistent, high-energy flows from receding glaciers capable of carving deep, sinuous paths into resilient bedrock like sandstone and chalk.
Elevated Water Tables: A historical environment where prehistoric river levels were significantly higher, sustaining active waterways in areas currently classified as “dry.”
Palaeochannel Transition: The natural evolution of active Mesolithic waterways into contemporary “dry” hollows as climate stabilisation lowered the regional water table.
Accepting these natural drivers effectively exposes the “Archaeological Pseudoscience” of the “traffic-erosion” theory. If a feature exists in deep solitude, far from historical urban centres, the human-erosion narrative is mathematically invalidated. Furthermore, the “military-frontier” theory for dykes collapses when the features are analysed through “Hydrology 101,” revealing them to be functional maritime canals.
3. Technical Standards for LiDAR Data Acquisition
Traditional surveys are rendered obsolete by surface noise. High-resolution LiDAR (4K, 5K, and 8K) is mandatory to bypass modern infrastructure and reveal the underlying quaternary geology. Analysis must be conducted within 3D viewing software and flyover simulations to replicate a professional remote sensing workflow.
Technical Requirements for Feature Validation
Resolution Tier
Diagnostic Capability
Primary Application
4K Quality
Basic relief mapping; identification of modern agricultural scarring.
Initial site spotting and large-scale regional overviews.
5K Quality
Morphological differentiation; identifies rounded profiles and sinuous paths.
Distinguishing between natural erosion and deliberate human quarrying.
25 sq. km tiles for 3D flyover analysis of landscape-scale canal systems.
The application of 8K precision is the pivot point for site reclassification. It allows for the identification of “rounded, sinuous forms” indicative of natural water flow, as opposed to the “angular, man-made cuts” associated with historical resource extraction. This precision is the only defence against “The Great Antler Pick Hoax,” which posits that primitive tools were responsible for massive landscape engineering.
4. Morphological Analysis: Differentiating Natural Flow from Human Intervention
Morphological rigour is the primary directive. The geometry of a feature dictates its classification, regardless of its proximity to known archaeological sites or established myths.
Profile: Angular, precise cuts with sharp transitions characteristic of quarrying.
Path: Straight, purposeful lines that override natural topographical flow.
This morphological rigor proves that Chinnock Hollow (Yeovil) is an empirical palaeochannel. LiDAR imaging reveals a sinuous form etched into resilient sandstone and chalk bedrock—a feat impossible for human footfall or cart traffic, which “Ivory Tower” narratives conveniently ignore.
5. Categorical Investigation Procedures: Dykes, Holloways, and Canals
This protocol demands a recursive re-evaluation of Britain’s “Great Dykes” and “Sunken Lanes,” dismantling the hoaxes of “Saxon Dykes” or “Iron Age Forts.”
Mandatory Investigative Directives
Holloways: Conduct a recursive search for dried-up springs and historical environmental contexts. If the feature is etched into resilient bedrock (sandstone/chalk) and exhibits a sinuous profile, it must be classified as a meltwater-carved palaeochannel. The “traffic thread” narrative must be discarded if the feature is located in deep solitude.
Dykes (Prehistoric Canals): Reclassify features like the Wansdyke and Car Dyke as standardised canal systems. The Car Dyke is specifically a Mesolithic canal. These features must be analysed as maritime infrastructure designed for “From the Rhône to Wansdyke” trans-European connectivity, utilised by standardised prehistoric canal boats.
Earthworks and Hillforts: Treat “military way” and “defensive fort” labels as hoaxes. Specifically, the “Military Way” and “Stanegate” at Hadrian’s Wall are historical misidentifications. Investigators must use LiDAR to identify hydrological connections. For example, Durrington Walls must be reclassified from a “henge” to a managed Mesolithic landscape featuring platforms and fish traps integrated into a ditch-and-waterway system.
6. Protocol Synthesis and Forensic Reporting
This protocol marks the final transition from “archaeological pulp fiction” to empirical, LiDAR-based forensic science. The “Ivory Tower Collapse” is inevitable as geospatial data replaces romanticised hearsay. Site investigators are required to produce reports that prioritise empirical signatures over established narratives.
Critical Takeaways for Site Investigators
Priority of Hydrological Context: Mandatory Directive: Always evaluate features as potential watercourses (palaeochannels or canals) before considering human-centric myths.
Resolution-Driven Validation: Only 5K-8K LiDAR tiles provide the precision necessary to validate groundwater fractals and the organic signatures of post-glacial flow.
Rejection of Defensive Assumptions: Question all “defensive” labels. If a feature aligns with the Post-Glacial Flooding Hypothesis or functional maritime engineering, the military interpretation is a documented hoax.
This protocol ensures the “mythical” is finally replaced by the “empirical,” utilising advanced remote sensing to reveal the true prehistoric landscape of Britain.

Join us as we continue to explore the fascinating mysteries of the past and reshape how we understand our history.
This year has seen a variety of fascinating and thought-provoking blog posts. Here’s a list of the posts published, with a brief description of each:
The feature long attributed to the Dorchester Roman aqueduct presents a fascinating but contentious case within archaeology. Its winding route, peculiar design, and unsubstantiated functional claims challenge conventional interpretations of Roman engineering in Britain. In this blog, we delve into key aspects of the feature, including its gradient, design, and capacity to deliver water, to uncover whether it truly served as an aqueduct or had a different purpose entirely. By critically examining the evidence and incorporating modern methodologies like LiDAR, we aim to provide a fresh perspective on this enigmatic structure.
The winter solstice, occurring around December 21st in the Northern Hemisphere, marks the shortest day and longest night of the year. This celestial event has been celebrated for millennia, symbolizing the rebirth of the sun and the promise of longer days ahead. Long before Christianity shaped the holiday calendar, ancient cultures observed the solstice with rituals and festivities that laid the groundwork for many modern winter traditions. .
We presented Paul Whitewick’s video on Wansdyke to an AI for analysis, comparing it to the scientific evidence detailed in my book on the subject. The results were unexpected—the AI dismissed the video entirely, viewing it more as a creative piece of art than a credible historical account. But don’t take our word for it—listen to the audio, read the transcript, and draw your own conclusions..
We compiled all the latest available knowledge about Neanderthals, Homo sapiens, and their potential interbreeding and fed it into an AI engine. We aimed to explore how a species like the Cro-Magnon might have developed as a hybrid between these two groups. Specifically, we asked the AI to analyze the likely physical appearance and attributes of such a species if they inherited traits from both Neanderthals and Homo sapiens. The key parameters we provided included their robust hybrid genetics, their reliance on a non-agricultural diet of high-protein foods like reindeer meat, fish, and fruit, and their tendency to interbreed primarily within their own hybrid group rather than with other Homo sapiens populations.
The study by, Schulz Paulsson, (Bettina. (2019). Radiocarbon dates and Bayesian modeling support maritime diffusion model for megaliths in Europe. Proceedings of the National Academy of Sciences. 116. 201813268. 10.1073/pnas.1813268116.) which uses Radiocarbon dates and Bayesian modelling, supports the maritime diffusion model for megaliths in Europe and offers a transformative perspective on the origins and spread of megalithic structures across Europe. This research challenges traditional narratives through cutting-edge radiocarbon dating and Bayesian statistical modelling and provides compelling evidence that maritime routes played a pivotal role in disseminating megalithic culture.
Over a decade ago, I proposed a groundbreaking idea that challenged conventional archaeology and geology. Drawing on 30 years of experience in landscape archaeology and cartography, I argued that rivers during the post-glacial period were significantly higher than they are today. Contrary to long-held geological assumptions that the meltwater from the last Ice Age vanished without a trace, I suggested that much of it remained, creating elevated waterways. These raised rivers, I posited, were pivotal to prehistoric life, providing essential routes for the construction of megalithic sites along their edges using advanced boat technology—astonishingly, over 5,000 years before archaeologists had traditionally believed such maritime innovations existed.
This post presents findings from a LiDAR investigation of Hambledon Hill, arguing it is not an Iron Age fort. Hambledon Hill’s significance as a prehistoric site continues to reshape our understanding of early Britain. Far from a simple Iron Age hillfort, the site reveals a complex history with roots in the Mesolithic period, dating back around 8,000 years. Recent findings challenge the earlier classification of a causewayed enclosure, instead uncovering a landscape marked by multiple pits and quarries, which suggests a hub for trade and social activity rather than a defensive stronghold.
I’m challenging the long-held belief that many sites across Britain, traditionally labeled as “Iron Age Hillforts,” were built primarily for defence. Instead, I argue these sites, rather than being fortresses meant for warfare, were vibrant centres of trade and commerce, with unique features that connect them to waterborne transport and economic activity. By meticulously examining archaeological findings and employing the latest LiDAR technology, I aim to deconstruct the conventional narrative surrounding these sites, focusing on three prominent examples: Danebury, Maiden Castle, and Old Sarum.
This post describes a personal journey into understanding Britain’s flooded past. My recent exploration into Britain’s prehistoric landscape has opened my eyes to a fascinating and often overlooked aspect of our history: the impact of post-glacial flooding. The sheer magnitude of meltwater released at the end of the last ice age dramatically reshaped the environment, creating vast waterways that are notably more significant than the rivers we see now. This realisation has sparked my curiosity to understand how these ancient waterways influenced the lives of our ancestors and shaped the landscape we know today.
This blog post examines the Cissbury Ring over time using LiDAR technology. This is a journey through time looking at the prehistoric site of CISSBURY RING and its surrounding Landscape based on the new third (2020) edition book of the best seller – that contains conclusive and extended evidence of Robert John Langdon’s hypothesis, that rivers of the past were higher than today – which changes the history of not only Britain, but the world. In his first book of the trilogy ‘The Post-Glacial Hypothesis’, Langdon discovered that Britain was flooded directly after the last Ice Age, which remained waterlogged in to the Holocene period through raised river levels, not only in Britain, but worldwide.
This post refers to a podcast about Car Dyke on ABC News. The book ‘The Car Dyke LiDAR Atlas’ presents a thorough investigation of the Car Dyke, a large ancient waterway in Britain. Using LiDAR technology, the author argues that the Dyke is much older than previously thought, dating back to the Mesolithic/Neolithic periods, and was likely used for transportation and water management rather than simply as a Roman drainage channel or defensive barrier. The book features detailed maps and analysis of the Dyke’s construction and course, including insights into the surrounding landscape and archaeological finds, to support the author’s conclusions.
Pillow mounds have traditionally been interpreted as medieval rabbit warrens, but recent archaeological discoveries suggest a far older and more significant role tied to Bronze Age cremation rituals. Evidence uncovered in recent excavations, combined with historical parallels from other sites, points to these mounds being used for cremation or as places for the burial of ashes, later repurposed during the medieval period for rabbit farming. Below, we explore the evidence from recent excavation reports that supports this hypothesis, showing how discolored soil, charcoal remains, and burial practices align with Bronze Age funerary rituals.
Pillow mounds have long been identified by archaeologists as rabbit warrens—structures built during the medieval and post-medieval periods to manage rabbit populations for fur and meat. These long, low earthworks, often equipped with drainage ditches, were thought to provide ideal conditions for rabbits to burrow and breed. The case of Trowlesworthy Warren on Dartmoor is a well-known example, where there are now believed to be 64 pillow mounds spread across a 5 km area. However, recent archaeological findings and a closer look at the logistics of large-scale rabbit farming in this landscape challenge the established interpretation.
The video (not mine!!) provides a valuable visual of the landscape around White Sheet Camp, illustrating how much detail is obscured when viewed from ground level. This highlights why traditional methods of landscape surveying, which relied heavily on ground-based observation, often missed key features. Unsurprisingly, many peer-reviewed books contain inaccuracies, as walking the terrain without modern tools like LiDAR leads to an incomplete understanding of these ancient sites. The video helps to demonstrate the importance of using advanced technologies in revealing the full complexity of these historical landscapes, rather than subjective observations. Note that the Neolithic Causeway is the Cross-Dyke and the Barrow is probably a fire beacon for the boats to follow to the trading site.
This post discusses whether archaeology is a reliable science. Archaeology, often hailed as the key to understanding our past, stands at a contentious crossroads between the humanities and the sciences. Archaeology is largely interpretative and subjective, unlike pure sciences, which rely heavily on quantitative data and mathematical models to test hypotheses. The field depends on analysing artefacts, structures, and cultural remains, often incomplete or degraded. This reliance on fragmentary evidence means that much archaeological interpretation is speculative, making it difficult to draw definitive conclusions. The subjective nature of archaeology raises questions about its scientific rigour, as interpretations can vary significantly depending on the archaeologist’s perspective, cultural background, or theoretical framework.
This blog explores the use of mathematics to reveal the Mesolithic origins of Car Dyke. In archaeology, theories about ancient structures and sites have traditionally been shaped by subjective interpretations, often constrained by the limited evidence. The lack of precise data, historical bias, and conflicting narratives have left the field somewhat speculative. However, recent advancements in mathematical modelling have introduced new ways to derive data-driven conclusions. We can dig deeper into the ancient past by applying Bayesian and Spatial Analysis, extracting valuable insights with greater certainty. One particularly compelling case study is the re-evaluation of Car Dyke, a linear earthwork historically associated with Roman engineering. Through these combined mathematical approaches, we have uncovered evidence that suggests Car Dyke may have been constructed much earlier than previously thought, potentially dating back to the Mesolithic period.
This post presents findings from a LiDAR investigation of the northern section of Car Dyke. Car Dyke is one of the most enigmatic and intriguing remnants of Roman engineering in Britain. Stretching across the Fens of Eastern England, this ancient waterway has puzzled historians, archaeologists, and enthusiasts for centuries. Theories about its purpose and origin are as varied as they are compelling, reflecting the complexities of interpreting ancient structures without definitive historical records. This introduction aims to present a comprehensive overview of Car Dyke, encompassing both past and current theories regarding its use and origin.
This post reconsiders the traditional understanding of the Vallum and Offa’s Dyke as ancient boundaries. History brims with unsung heroes, those outsiders whose contributions leap from the shadows, not through the traditional channels of academic rigour but via the sheer force of innovative thought. These individuals, often sidelined by mainstream science for lacking formal credentials, have propelled progress with their unorthodox insights. In his eloquent reflections on science and humanity, Jacob Bronowski would have appreciated these figures ‘courage to challenge established disciplines’ dogmas and orthodoxy. Through their unconventional viewpoints, they invite us to step out of the “propaganda box” of discipline norms and reconsider the broader knowledge landscape with fresh eyes
This post is about a character named Professor Bonkers, and their perspective on the world of archaeology. We have examined the efforts of Professor Ray in his endeavour to prove that transporting bluestones by land to Stonehenge using sledges and dragging is feasible. He believes the journey is relatively flat with gentle gradients, based on his walk on modern roads engineered for gradual steepness over the last thousand years. However, he failed to consider the reality of the steep drops and river valleys the original journey would have encountered.
This post presents the findings of a LiDAR investigation of South Cadbury Castle, also known as Camelot. The hillfort is formed by a 7.28 hectares (18.0 acres) plateau surrounded by ramparts on the surrounding slopes of the limestone Cadbury Hill. The site has been excavated in the late 19th and early 20th century by James Bennett and Harold St George Gray. More recent examination of the site was conducted in the 1960s by Leslie Alcock and since 1992 by the South Cadbury Environs Project. These have revealed artifacts from human occupation and use from the Neolithic through the Bronze and Iron Ages. The site was reused by the Roman forces and again from c. 470 until some time after 580. In the 11th century, it temporarily housed a Saxon mint. Evidence of various buildings at the site has been unearthed, including a “Great Hall”, round and rectangular house foundations, metalworking, and a possible sequence of small rectangular temples or shrines.
This post seems to discuss the theory that Stonehenge was used as a hospital. Timothy Darvill, a distinguished figure in Archaeology at Bournemouth University, has put forward a groundbreaking theory. His proposition that Stonehenge was a healing sanctuary, as detailed in his book ‘Stonehenge: The Biography of a Landscape ‘, is supported by compelling evidence from human remains found in burial mounds near the site. These remains, Darvill argues, belonged to individuals who were ailing before their demise, suggesting a unique purpose for the monument.
This blog post explores prehistoric burial practices in Britain. Prehistoric Britain saw complex and evolving burial practices, starting with the excarnation of bodies. Dolmens, characterised by their capstones balanced on upright stones, were used as platforms to expose bodies to birds, and wooden palisades encircled the platform, preventing terrestrial animals and rodents from scavenging
This blog post addresses the question of whether archaeology is becoming obsolete. There are many challenges archaeology faces as a discipline. The historical misconceptions and the evolving understanding of our past are significant aspects of archaeological study
This post explores the top ten misidentified fire beacons in British history, using LiDAR. Misidentification of objects by archaeologists is an unfortunately frequent occurrence, particularly evident in the study of prehistoric fire beacons. This phenomenon can often be attributed to the curricula of archaeological academic programs, which may not always foster a rigorous scientific attitude. This issue is compounded by the perception that these programs are less demanding than disciplines like physics, chemistry, and biology, which typically require a more robust foundation in logic and mathematics for professional success.
This post examines the Great Chichester Hoax, possibly concerning a misidentified bridge, using LiDAR. It seems I’ve once again stirred up some controversy among the old archaeology club members of Chichester. A few years back, there was quite a buzz in Chichester when they unearthed a Roman Villa complete with a bathhouse. Eager to contribute, I headed to the site with my drone, hoping to capture aerial shots. However, my offer was turned down, perhaps due to the slew of questions I posed to the lead archaeologist. I was particularly intrigued by the water sourcing and drainage for the bathhouse, especially given the presence of the prehistoric dyke that ran through the park. Yet, they seemed to disregard the sizable bank at the edge of the cricket ground.
Maiden Castle, Britain’s largest Iron Age hill fort, has always been a subject of fascination and mystery. Its impressive size and strategic location suggest it was once a significant military stronghold. However, recent advancements in archaeological technology, specifically Light Detection and Ranging (LiDAR), have sparked debates about the actual feasibility of defending such a vast fortification by examining the logistical requirements necessary to sustain a large garrison here, juxtaposed with the lack of physical evidence for such activity, a new narrative emerges, challenging traditional interpretations of Maiden Castle’s historical significance
Archaeology often presents the megalithic structures of Northern Europe as enigmatic remnants of the past, but traditional interpretations of their purposes—defensive or territorial—are increasingly challenged by new research. These ancient monuments, including Stonehenge and Silbury Hill, required a level of logistical and communal organisation akin to modern engineering feats like the Channel Tunnel, suggesting sophisticated, large-scale cooperation among prehistoric societies. This blog post explores how regular trading and the use of established transportation networks likely supported such monumental projects. It argues that the labour force involved was large and part of a highly structured society, possibly operating under an early compensation system for their colossal efforts. As we delve deeper into these ancient marvels, we uncover a society that may have been as advanced and cooperative as any known civilisation, revealing a new appreciation for the capabilities and ingenuity of our ancestors.
Peering into the mists of prehistory, we discern figures as monumental as the structures they erected. The Cro-Magnons, our Homo Superior ancestors, tower over early European landscapes not only in their formidable physical stature but also through their enduring contributions to ancient engineering and societal development. This essay delves into how their exceptional physical and cognitive abilities enabled them to construct massive stone monuments across Northern Europe, reshaping our understanding of Stone Age capabilities.
Recent carbon dating from the Bluestone quarry sites offers compelling and irrefutable mathematical evidence that Stonehenge’s construction dates back to the Mesolithic era. This new data suggests Stonehenge is 5000 years older than experts had previously believed, challenging established views on its origins and adding new depth to our understanding of this ancient monument.
I’ve always been fascinated by how archaeological discoveries can unravel threads of history. Still, they can also become entangled in webs of misinterpretation and incorrect dating, leading to significant findings being dismissed or misunderstood. A case in point occurred in a Welsh housing estate where ancient slipways were initially mistaken for longhouses. This confusion sparked a question: why would such elaborate structures be necessary for something as simple as a lightweight dugout canoe?
The connections between the legends of Atlantis and Hyperborea, and the works of Homer represent a fascinating intersection of myth, philosophy, and epic narrative within ancient Greek literature. These stories not only provide insights into the geographical and cultural understandings of the Greeks but also reflect deeper philosophical and ethical concerns that permeate Greek thought. Below, we explore these themes in greater detail, delving into how these mythical and literary works intertwine and what they signify about ancient Greek civilisation.
Standing on the worn, weathered path of a holloway, enveloped by the towering earthen walls on either side, I often contemplate the origins of these enigmatic features. As a wanderer drawn to these ancient pathways, I’ve always been fascinated by the layers of history and mystery that seem to permeate the very soil beneath my feet. Holloways, these sunken roads carved into the landscape, carry with them the aura of countless stories, but their formation captivates my curiosity the most.
The third book in my trilogy aims to weave together the discoveries made across Britain, with a particular focus on Stonehenge, to shed light on a civilisation that archaeologists have termed the ‘megalithic builders.’ This civilisation is markedly distinct from those that came after, showcasing an extraordinary level of capability and engineering skill in moving vast stones and constructing earthworks that have endured for nearly ten thousand years. These achievements are even more striking when compared to the structures left by the Romans, who occupied these lands for hundreds of years yet left behind fewer enduring monuments.
The papers published by researchers from the University of London, Southampton, and Manchester, including Mike Parker-Pearson and his team, regarding the discovery of the quarries at Craig Rhos-y-Felinand the bluestone megaliths at Carn Goedog have been a significant contribution to our understanding of Stonehenge’s origins. This research brought to light the fascinating theory that Stonehenge was initially constructed in Wales and then transported to Salisbury Plain around 500 years later.

If you study archaeology at university or even on an ordinance survey map at length, you will notice strange earthworks on the sides of hills of Britain, with no rational explanation as to why they are there and for what reason. These features are mostly ignored at university, or an excuse is made for their construction. The reality is that these features do not make any sense unless there are other factors in operation which have been ignored.
The first thing to notice is that the word ‘Dyke’ is associated with water. It does seem strange you would call an earthwork on top of a hill a Dyke, unless there was some history passed down through the years to its actual use. If we look at the most famous Dyke in Britain, ‘Offa’, we notice that it is attributed to a Saxon King and, therefore, could not be prehistoric. Or is this a clear indication of how archaeologists find excuses for these features rather than factual, empirical evidence?
This essay series culminates in a comprehensive analysis of the origins and transportation methods of the stones used at Stonehenge. It features the first detailed LiDAR maps of the areas surrounding the stone sources, enriched by references to research that helped in their identification. These maps critically assess whether the stone sites are situated near ancient roads or along the margins of paleochannels, which are old waterways. The analysis strongly suggests that these waterways were likely the sole means of transporting the stones from their original locations to the previously identified mooring points at Stonehenge. Intriguingly, these mooring points have, until now, been largely overlooked by archaeologists. This conclusion not only underscores the significance of integrating technological advancements like LiDAR into archaeological research but also challenges long-held assumptions about prehistoric engineering capabilities and the ingenuity of our ancestors.
Exploring the origins and transportation of the stones used to construct Stonehenge continues to be a fascinating subject, ripe with theories and controversies. The viral interest generated by my blog post this week, which highlighted a map showing three known sites of the stones’ origins, barely scratches the surface of this complex logistical puzzle. Indeed, there are stones from even greater distances, opening a myriad of questions about how these megaliths were transported to their final resting place at Stonehenge. This essay aims to delve deeper into these logistics, providing a comprehensive overview based on the latest research and theories.
In the past ten years, I have faced significant challenges in establishing the validity of my claim that Linear Earthworks are prehistoric canals. Many people have dismissed my theory, but I have not let that stop me. I undertook a comprehensive survey of 1500 Historic England’s Scheduled Linear Earthworks, and the findings culminated in the first book of a quadrilogy series detailing the East Wansdyke area. This publication is a significant personal milestone and an unprecedented achievement in the field of archaeology that no university or research team has matched.
Over the recent span of years, there has been a marked tendency to present images of climatic upheaval—storms that rend the fabric of local communities and touch the lives of individuals with their tempestuous hands. In the discourse on flooding, an almost theatrical emphasis is placed upon the metrics of catastrophe: the voluminous descent of rain and the gales’ ferocious velocity. Amidst these narratives, a phrase of gravitas, ‘since records began,’ is often delicately woven, lending weight to the tales of unprecedented climatic fury that segment our years into records of seasonal extremities.
At the outset, the clay-with-flints, a vestige of ancient weathering and erosion, stands as a testament to the relentless forces of nature that sculpted the landscape. Born from the remnants of Palaeogene sediments and the dissolution of chalk, these deposits serve as silent witnesses to the Pleistocene’s cold embrace. Their presence on the hilltop flats signifies a chronological anchor, predating the rhythmic succession of river terraces that stitch the valley’s quilt.
Fifteen years have elapsed since I introduced what some might label a ‘revolutionary’ concept, a brainchild born from my earlier explorations in archaeology. My investigations, particularly the graphical representation of 50 sites encompassing Stonehenge and its surrounding barrows, revealed a striking pattern: all these locations consistently occupied the upper 30 percentile, perched halfway up a hill or higher for the uninitiated.
In the profound tapestry of human history, the emergence of Lidar archaeology technology stands as a beacon, illuminating hidden chapters and rewriting the narrative of our past. As we traverse the landscapes of antiquity, a remarkable revelation comes to light through the lens of Lidar – the Linear Earthworks that crisscross our ancient terrains. Driven by laser precision, this technological marvel exposes a new dimension in historical understanding that challenges conventional wisdom and prompts us to reconsider the nature of these enigmatic earthworks.
In the latest installment of Digging for Britain’s Season 11, the spotlight turns to the intriguing Caerfai Promontory Fort, also known as Penpleidiau, perched on the edge of Wales. Nestled approximately 1.3km southeast of St David’s, this archaeological site, with its formidable features, compels a reevaluation of traditional interpretations and invites us to question the prevailing coastal ‘Hill Fort’ narrative.
In the first part of our exploration, we delved into the televised program ‘Digging for Britain’ and scrutinised the methodology employed by the purported experts, questioning the reliability of their conclusions regarding the dating of Cerne Abbas. Our investigation highlighted flaws in the sampling process, particularly the oversight of soil creep, which significantly impacts the interpretation of the site’s history.
Recently, I received a message from my friend Chris at Lambourne Photography who shared new winter photos of Avebury. The landscape, experiencing recorded rainfall, has begun to flood, capturing my keen interest. This flooding aligns with the predictions in my prehistoric Avebury maps, considering the post-glacial flooding during the Mesolithic period (10k to 4k BCE).
In a recent instalment of ‘Digging for Britain,’ Alice Roberts stirred the archaeological pot by asserting that the Dorset Chalk Giant (Cerne Abbas) had Saxon origins rather than the presumed prehistoric roots. The revelation added a layer of intrigue, especially for someone like me, deeply entrenched in Landscape Archaeology. At first glance, the giant’s features seemed to echo a Neolithic connection, reminiscent of the Uffingham White horse. Both figures boasted natural harbours in the hillside, suggesting potential prehistoric maritime use.
As the waters began to recede, the architects of Stonehenge found themselves confronted with a formidable engineering challenge: how to contend with the diminishing groundwater table while ensuring the Stonehenge moat remained adequately filled. In the preceding discussion, we established the application of a clay waterproofing layer to transform the Stonehenge moat into a reservoir akin to a dew pond. In this chapter, I delve into the intricacies of their solution—a newly constructed earthwork known as ‘The Avenue,’ complete with its own moat designed to bring the waters closer to the monumental bathing moat.
Robert John Langdon has also created a YouTube web channel with over 100 investigations and video documentaries to support his classic trilogy (Prehistoric Britain). He has also released a collection of strange coincidences that he calls ‘13 Things that Don’t Make Sense in History’ and his recent discovery of a lost Stone Avenue at Avebury in Wiltshire called ‘Silbury Avenue – the Lost Stone Avenue’.(2024 Prehistoric Britain Blog Review)
Langdon has also produced a series of ‘shorts’, which are extracts from his main body of books:
