Twelve thousand years ago, according to our written history, the glaciers from the last Ice Age finally melted, revealing the Britain we know today. For over 100,000 years (at the end of the Pleistocene Epoch) Britain had been underneath two miles of ice, compressing the ground by its sheer weight, so much so, that the land surface was then some 2000 feet below its original level. Which has consequently risen back slowly, to become the Britain we know today. Geologists have assumed that theses glaciers melted due to warming in climatic conditions creating a series of 'meltwater pulses' over a short period of time, but they have failed to date to produce a realistic model that fits the total meltwater discharge which eventually created not only the North and Irish Seas but hundreds of feet of sea-level rises that we are still experiencing today. If you study any British Geological Society (BGS) map of Britain, you will notice it shows a series of bedrock, sedimentary and superficial deposits. Below these deposits, is a labyrinth of material that look like canals and gigantic waterways which lay under the surface on top of the bedrock, which is the remains of Palaeochannels from the last ice age. This evidence is a testament to how the landscape would have looked when the river was at its highest and discharged its maximum water levels. These superficial deposits that resemble ancient rivers can be seen on the surface and are known to archaeologists, geologists and the general public as 'Dry River Valleys' - because the river valleys are today, currently dry. These great waterways can be readily seen in profile in the cliffs and valleys of the South Downs, where they show their curved river nature by the remains of the superficial subsoil consisting of sand, silt and clay. Past geologists have failed to identify these huge concave broken chalk sections of the cliffs accurately, or the river terraces from the remains of the meltwater of the last glaciation (LGM), which would have created as they historically have only identified the gravels and bedrock within geological periods. Their arguments are compounded as they fail to explain why they are relatively short distances from the sandy silt to today's topsoil or why silt and sand are at elevations above supposed earlier river terracing, so they suggest these deposits are 'windblown Loess' - blown into position rather than laid down by rivers of the past. This book uses existing scientific evidence from peer-reviewed publications and modern mathematical models to give you an understanding of how the landscape looked in the Holocene period, giving archaeologists the tools to reveal fresh discoveries and a better understanding of our history.
