This geological evidence can clearly be seen in the cliffs and valleys of the South Downs. Just like the Stonehenge region, this area has the same chalk sedimentary bedrock and ancient post-glacial rivers. Evidence for these rivers are found by the subsoil consisting of sand, silt and clay. This subsoil can be seen in the valleys (known as deans) of the South Downs and most graphically in the exposed face of the white chalky cliffs that have been eroded by the sea giving us a perfect ‘dissection’ of a typical prehistoric waterway. Modern geologists have yet to identify these huge concave sections of the cliffs, as being the remains of the ice melt from the last glaciation which had filled with water leaving the sandy sediments embedded in the chalky sedimentary rock face, just after the great melt, some 15,000 years ago, instead they claim they are ‚windblown’ loess or wash from the valley walls.
The South Downs showing the sand under the top-soil
What they can’t explain is the relatively short distance from the sandy soil to today’s top soil and the exact date of this sandy sediment. If you look closely at the cliffs, you will see the sandy remains of the river is touching the top soil. If this dry river valley was as old as some archaeologists and geologists suggest - where is the rest of the top soil?
If the top soil erodes as quickly as some ‘experts’ also suggest - why is there 18 inches of top soil on top of the chalk today when there should be none or are we expecting some massive climatic event to wipe away the top soil in the near future, or is the dating of the prehistoric river beds and consequently dry river valleys totally incorrect?
As a matter of practice, archaeologists investigating Stonehenge have always ignored the obvious dry river valleys that surround the site. For they have incorrectly perceived that this area looked similar as today in the time of Stonehenge’s construction and therefore, they falsely believe that these river valleys were dry not wet in the Mesolithic and Neolithic Periods.
Proof of Hypothesis No.1
Due to the size and location of the last glaciation, water from the ice cap must have flooded the landscape causing the rivers to rise and turning the landscape into a ‘flooded island environment’
Chapter 1 – The Land called DOGGER
One of the strangest mysteries in archaeology is the disappearance of Doggerland. This was a land mass the size of Ireland, which lay approximately 50 miles east of Norwich, between Britain and Denmark - within what is now known today as the North Sea.
Until very recently, we were unaware of Doggerlands existence. Past geological theories proposed that the North Sea and the English Channel were formed by the rising water at the end of the last Ice Age 15,000 years ago. This theory was accepted for a long period of time as it fitted with the traditional view of our prehistory. However, over the past 100 years fishing boats and in recent times Dutch trawler men, while fishing at the bottom of the North Sea, repeatedly found evidence of tools from post-Ice Age occupation.
Initially, because of existing archaeological theories, it was suggested that these finds were from a pre-Ice Age Europe, when Britain was still connected to the continent. Subsequent evaluation, however, showed that the level of sophistication in the construction of these tools that showed to be the work of skilled Mesolithic or Neolithic people, i.e. after the Ice Age.
Sonar images obtained by the wealthy companies prospecting for oil and gas provided the answer to this mystery by discovering a land mass we now call ‘Doggerland’ which lays 15 to 60 metres under the North Sea. The current view held by both geologists and archaeologists is that this land did in fact existed in Mesolithic period (10,000 BCE to 4500 BCE) but disappeared with the rising sea levels, caused by the melting ice caps.
However, this theory is fundamentally flawed.
The problem is the Ice Age ended at least 5,000 years BEFORE the Doggerland was swamped - geologists will tell you that the water came from ice cap of the last ice age. But it does not take 5,000 to 10,000 years for an ice cap to melt in the Northern Hemisphere. If it did, why is there so much fuss about Global Warming today – if the risk of flooding was 5,000 years down the line? The truth is that there is a large hole in the current post Ice Age theory.
Where was the water for those thousands of years before it engulfed Doggerland?
In an attempt to validate this unfounded, almost ludicrous sea level theory, they have even suggested that tsunamis played a part in the submergence of Doggerland. Now, it is quite possible that Doggerland was hit by a massive wave resulting from the collapse of a continental shelf, but as we have seen recently with the 2004 Indian Ocean disaster in Sumatra and more recently 2011 in Japan, the wave only temporarily covers the land, it does not sink the landmass completely.
After the initial destruction, the water would then recede. At the time geologists estimate this tsunami, 7,000 years ago, it would not have covered Doggerland permanently unless the sea level had risen at the same time and obviously, vast quantities of NEW water would be needed for that event. The second problem with the ice cap melting theory is one of displacement. When ice melts in the sea, it does NOT raise the sea level as reported in our media. This simple process can easily be seen with ice cubes in a glass of water. When the ice cubes melt the water in the glass does not overflow, in fact the water level decreases, because (as any housewife knows) when you freeze water in your fridge the volume increases. Consequently, frozen ice displaces more water not less!
So why did the sea level rise and cover Doggerland?
Doggerland sinks thousands of years after the Ice Cap melts
The simple answer is that the water that makes up the North Sea and English Channel was “sitting on” the land and was released into the sea very slowly, over a period of time. My hypothesis being proposed here is that, when the ice melted on the land, the environment was swamped by immense floods and as we have now shown, these floods can be seen in the geological post-glacial river bed as superficial deposits of sand and gravel. All of the melting ice water did not run into the sea for of two main reasons; the land mass had been compressed (known to geologists as an ‘isostatic transformation’) and therefore sunk into the earth’s surface due to the colossal weight of the ice cap (‘glacial loading’) and secondly, the nature of the soil below us allows water to seep into the bedrock which is stored in vast groundwater reservoirs known as ‘aquifers’.
Over the course of the next 10,000 years the groundwater slowly seeped from the aquifers through the rock bed into the sea. This was because the land mass started to recover from the ice age squashing and started to rise up to its normal height “Isostatic Rebound”. This released greater amounts of groundwater into the sea, to eventually cover the low lying lands including Doggerland.
This recovery from the ‘isostatic transformation’ is still seen in parts of Scotland as the landmass around the Forth, Tay and Clyde Valleys rises about 2mm every year. All this evidence suggests that at the end of the ice age the British landmass flooded with so much groundwater that it took up to 10,000 years for all this flood water to move from the soil and bedrock to the seas - raising sea levels.
But what is Groundwater and where does it come from?
The water cycle and the underground reservoir (aquifer)
Hydrology and Groundwater (from the UK Groundwater Forum)
The presence and flow of groundwater is the key element to my hypothesis, so it is worth spending bit of time in understanding what this substance is and how it flows invisibly under our environment.
When a hole is dug in permeable rocks, at a particular depth water begins to flow in. The surface of the water that accumulates in the hole is the water table and the water in the ground below the water table is groundwater. The variations in the shape of the water table reflect the topography in a subdued form. The water table is near the ground in valleys, actually intersecting the ground surface where rivers, lakes and marshes occur, but it is at much greater depths below hills.
The pore spaces of rocks are saturated with water below t
he water table and groundwater is said to occur in the saturated zone. Immediately above the water table, water is drawn up into pore spaces by capillary forces into a thin zone called the capillary fringe. Rocks above the water table, including the capillary fringe, form the unsaturated zone; although they do contain water they are generally not completely saturated, and the water cannot be abstracted.
Water is continually moving through the environment – we call this the water cycle. Water evaporates from the oceans, condenses into clouds and then falls on the land surface as rain, only to flow into rivers and back into the sea. However, there is one aspect of the water cycle that is often forgotten – groundwater. Rainfall doesn’t only reach rivers by running off over the land surface.
Most of the rainfall will soak into the soil, which acts like a giant sponge. In the soil some of the water will be taken up by plants and, through a process called transpiration, will return to the atmosphere, but some will soak further into the ground – a process called infiltration - and trickle downwards into the rocks, becoming groundwater. The level at which the rock becomes saturated is called the groundwater table. Water in this saturated zone will flow from where it has infiltrated to a point of discharge. This might be a spring, a river or the sea. Much of the flow of a river will be made up of discharging groundwater, and groundwater provides a vital role supporting wetlands and stream flows.
Water is present almost everywhere underground, but some geological formations are impermeable – meaning that water can hardly flow through them – and some are permeable – they contain fine holes that allow water to flow. Permeable formations that contain groundwater are known as aquifers. The holes that water flows through can be spaces between individual grains in a rock like sandstone, or they can be networks of fine cracks. Very occasionally groundwater will flow in underground rivers, but this is the exception rather than the rule.
Groundwater comes from rain. The average annual rainfall over the UK is about 1100 millimetres, ranging from more than 2500 millimetres over highland Britain to less than 600 millimetres on the lowlands of eastern England. A significant part, almost 500 millimetres in lowland areas, evaporates, mainly in the summer. The remainder is available to infiltrate permeable rocks although where the rocks have low permeability or, where they are overlain by layers of relatively impermeable clay, part will flow over the ground as surface runoff. Water infiltrates the ground mainly in the winter and slowly moves down through the unsaturated zone, eventually reaching the water table and becoming groundwater.
After temporary storage in the ground, groundwater drains from springs and seepages into streams and rivers. Maximum discharges occur at the end of the winter when groundwater levels are high following the seasonal infiltration. They steadily decline throughout the summer into the autumn. The contribution that groundwater makes to the flow of rivers is called base flow and it is responsible for maintaining the flow of rivers during extended periods of dry weather when surface runoff virtually ceases.
Groundwater provides about one-third of public water supplies in England and Wales, 7% in Northern Ireland and 3% in Scotland. The regional differences reflect the distribution of aquifers and the more favourable conditions for the development of surface water resources in both Northern Ireland and Scotland.
Groundwater makes up nearly 70% of all the worlds freshwater; only 0.2% is found in lakes, streams or rivers and 30% is bound up in snow and ice on mountains and in the Polar Regions. As rivers and lakes tend to be supported by groundwater, it is not exaggerating to say that almost all the water we use for agriculture, industry and drinking water is either groundwater or has been groundwater at some point in the water cycle.
Our major aquifers are the Chalk, Jurassic Limestones and Permo-Triassic sandstones, with substantial supplies available from other formations, such as river gravels and Carboniferous Limestone. Over recent years groundwater have been bottled for sale as mineral waters. Often these waters come from minor aquifers in upland areas where distinctive geology imparts interesting flavours.
It should be remembered that not all groundwater resides at sea level. The natural motion of water means that it moves from rainfall and springs down to rivers and eventually to the sea. However, the pace of this flow back to the sea is dependent on soil types and conditions. This is why we have lakes and reservoirs at high altitudes as they are situated on a form of impervious soil that does not readily leak water and they are constantly fed by small streams and constant rainfall - this variation is known as THE GROUNDWATER TABLE and varies throughout Britain.
Proof of Hypothesis No.2
Water from the ice cap from the last Ice Age flooded the British landscape resulting in newly formed and enlarged rivers with islands – this groundwater slowly receded from the land and moved to the North and Irish Seas, creating the English Channel and flooding Doggerland.
My analogy
This process can be illustrated more clearly if Britain is pictured as a giant dry sponge. If an ice cube was placed on the sponge, over time, the ice would melt and the water would soak into the sponge. The key factor here is the melting into the sponge, not out of the sponge to the surrounding areas. Eventually, the water will seep out of the sponge given sufficient volume leaving the majority of the water still in the sponge, this represents the nature of ‘groundwater’ and it has kept us alive since man has evolved two million years ago.
Geologists and Archaeologists would have us believe that the water from the last ice age just disappeared into the sea without a massive reaction to the land surface. If all the water from previous ice age just flowed into the sea without a detour into the massive aquifers under the soil then the rivers would have run dry long ago and man would have died for he would not have been able to dig the wells he has always needed to survive, if groundwater did not exist.
Chapter 2 – The Big Squeeze
As we have clearly shown in the previous chapter, when the ice caps covered the Northern Hemisphere at the end of the last Ice Age, it had a dramatic effect of on our planet’s hydrology. The weight of the ice also had another impact on the Continental Crust which scientists refer to as ‘Isostatic or Earth Transformation’. This process is so tremendous and widespread that it would have affected the whole of Britain, for thousands of years after the last Ice Age. The extent of this geological compression at our case site, Stonehenge to date is little known, so to understand the true nature of the phenomenon we need to look at more detailed investigations undertaken in other countries, to allow us to estimate the degree of transformation, which could have occurred.
Case Study - ‘Shorelines of the North American Great Lakes During the Past 20,000 Years’. James Clark from Wheaton College, 2008.
Great Lakes showing the depth of land surface over time
During historical times, water levels of the modern Great Lakes have fluctuated by more than a metre. This is largely caused by changing weather patterns and the associated rates of evaporation and discharge of rivers and groundwater entering and leaving the lakes. As ice advanced over the Great Lakes region the earth’s surface under the ice subsided, while the region beyond the ice bulged upward. In general, as the ice retreated, the process occurred in reverse.
Within Clark’s findings, he indicated that the earth’s surface had been compressed by as much as 700 metres over the last 20,000 years and has only recently (in geological terms) ‘bounced back’ to what we would regard as its present level. It’s logical to conclude therefore that here in Britain; a similar kind of transformation must have taken place. Geologists claim that the ice sheet spread down the West coast over the Irish Sea, as far as the Scilly Isles, but no further south than the Thames.
What’s critical to consider is the volume/weight of water contained within the Irish Sea, in comparison with that within the Great Lakes. The Great Lakes have a volume of some 23,000 cubic km of water, whereas the Irish Sea is 13,500,000 cubic km of water – over 600 times larger and therefore heavier than t
he Great Lakes.
Present geological convention suggests that this huge volume of ice only affected the landscape and groundwater tables only in Scotland, Wales and Ireland but not the rest of Britain. Geologists believe this because they have been able to monitor the existing rebound in Britain which shows that the North West of the country is still rising by 2 cm per annum whereas the South is sinking by 2mm per annum – the view being that if the South of Britain also had been covered by the ice sheet, it too would be rising.
Their conclusion is that the ice cap did not reach the South East corner of Britain and stopped along the River Thames, across to Bristol. The most overlooked feature of this isostatic rebound process is the fact that once squashed; the land actually rebounds back ABOVE its original height before the process started, before returning to its original position, as shown in the Great Lakes study. The simple reason to this unique effect is that we live on a continental shelf (or crust) that floats on the volcanic magma of the earth’s core. We are well aware that continental drift affects everyone as the ‚tectonic plates’ float on this ‚sea of lava’ but few geologists have recognised how isostatic transformation affects this mantle. It is my belief placing a large weight on a floating surface (such as the continental crust) and then removing it would induce a diminishing ‚sine wave’ effect on the land.
