The Post-Glacial flooding Hypothesis - V3.0 online

Some twelve millennia in the past, a significant chapter in Earth&#39;s history unfolded as the glaciers from the last Ice Age gracefully retreated, unveiling the foundation of the Britain we recognize today.<br><br>For over a staggering 100,000 years, the Pleistocene Epoch held Britain captive beneath the colossal weight of two miles of ice, an immense force that compressed the land, driving it approximately 2000 feet below its original level. In the aftermath of this glacial epoch, the gradual rebound of the land commenced, shaping the contours of the present-day British landscape.<br><br>The conventional geological narrative attributes the melting of these glaciers to a warming trend in climatic conditions, resulting in a succession of &#39;meltwater pulses.&#39; However, this explanation falls short of constructing a realistic model that accounts for the comprehensive discharge of meltwater, responsible not only for forming the North and Irish Seas but also for initiating significant sea-level rises that continue to shape our coastlines.<br><br>A perusal of any British Geological Society (BGS) map unveils a subterranean network of features, resembling canals and colossal waterways, concealed beneath the visible bedrock, sediments, and superficial deposits. These intricate formations represent the remnants of Palaeochannels from the last ice age, offering a glimpse into the past when rivers surged at their peak discharge levels.<br><br>These &#39;Dry River Valleys,&#39; as they are commonly known, manifest on the surface and can be observed in the cliffs and valleys of the South Downs. The distinct concave profiles of these ancient rivers are marked by the remnants of superficial subsoil, comprised of sand, silt, and clay. <br><br>However, past geological interpretations have often misidentified these features, failing to recognize their riverine nature and the significance of associated river terraces formed during the Last Glacial Maximum (LGM). The misinterpretation is compounded by the puzzling proximity of sandy silt to contemporary topsoil and the presence of silt and sand at elevations purportedly higher than earlier river terracing. Some geologists have attributed these deposits to &#39;windblown Loess,&#39; suggesting that prevailing winds transported the materials into position rather than the action of past rivers.<br><br>This book embarks on a journey to unravel this geological mystery, drawing upon existing scientific evidence documented in peer-reviewed publications and leveraging modern mathematical models. The aim is to provide readers with a comprehensive understanding of the Holocene landscape, empowering archaeologists with valuable insights to uncover fresh discoveries and attain a nuanced comprehension of our intricate history.<br><br>Post-Glacial Flooded Britain – V3.0 (Online Edition)<br><br>Twelve thousand years ago the ice melted.<br><br>But Britain did not simply “return to normal.”<br><br>This book argues — using measurable physics, geological mapping, peat chronologies, and river discharge modelling — that Britain remained hydrologically overcharged for thousands of years after the last Ice Age.<br><br>The case is built on four converging lines of evidence:<br><br>1. Meltwater Mathematics<br><br>Using ice-volume density calculations and global sea-level equivalence, the book demonstrates that the scale of meltwater released at the end of the Last Glacial Maximum far exceeds the simplistic models traditionally applied to Britain. The discharge volume demands prolonged continental drainage, not a short-lived melt event.<br><br>2. Misinterpreted Superficial Deposits<br><br>British Geological Survey maps reveal vast palaeochannel networks and dry valleys cut into chalk and bedrock. These have often been dismissed as windblown loess or minor surface processes. This work argues instead that they are the physical remains of rivers operating at magnitudes far beyond modern scale.<br><br>3. Peat as Hydrological Memory<br><br>Basal peats across Somerset, the Thames basin, Wales and beyond repeatedly indicate sustained standing water and saturated floodplains in the early Holocene. Peat becomes not incidental sediment, but a measurable indicator of raised groundwater and delayed drainage.<br><br>4. River Terrace Geometry and Discharge<br><br>Terrace spacing, valley cross-sections, and discharge case studies (Thames, Welsh catchments, North America, Black Sea comparisons) reveal a consistent pattern: rivers were once wider, deeper, and more energetic. Modern rivers are the reduced remnants of that system.<br><br>The central conclusion is stark:<br><br>Rivers of the past were larger than rivers today.<br><br>If that is true — and the data suggests it is — then prehistoric Britain must be reinterpreted within a high-water landscape. Settlements, monuments, trade routes, and landscape use were shaped by floodplain persistence, elevated groundwater, and shrinking rivers over millennia.<br><br>This book does not rely on mythology or symbolism.<br>It relies on physics, sediment, and measurable landscape geometry.<br><br><br><br><br>
