The Lancaster and Morecambe area was once part of Britain and Ireland’s largest and most deadly lake, according to new research.
The findings claim that Llyn Llion “the lake of floods” formed towards the end of the last Ice Age, around 18,000 years ago, and extended across the Irish Sea and north as far as Glasgow.
It was held in place by a wall of ice stretching from the Lleyn Peninsula in Wales to Wicklow in Ireland.
The lake was up to 15m above present day sea levels according to the claims published in a new ebook – Atlantis and the Biblical Flood: The Evidence at Last, by Philip Runggaldier.
Mr Runggaldier believes that when the ice gave way around 14,700 years ago, the lake burst south, killing many of the Stone Age inhabitants of southeast Ireland, coastal Wales and the West Country.
The author, who lives in Melksham, Wiltshire, also says there is evidence that refugees fleeing the devastation spread word across the continent and further afield about sprays of water as high as Ben Nevis, and that the flood could have been the source of the mythical “Biblical Flood”.
Glaciers pushing south from Scotland caused the wall of ice between Wales and Ireland to burst, but it also would have pushed up The Isle of Man.
According to stories passed down through the ages, The Isle of Man was a mystical island shrouded in mist at the centre of the lake, accessed via a walkable causeway from southern Scotland.
Mr Runggaldier, who has a Degree in Geography and a lifelong passion for maps, said: “It is thought that early Stone Age people probably reached the Lancaster area.
“If so, they found there a huge lake 10–15m (33–50ft) above current Irish Sea levels.
“New evidence shows that this lake extended across the Irish Sea and north as far as Glasgow. It was known as Llyn Llion ‘the lake of floods’ and formed towards the end of the last Ice Age.
“It’s a theory based on a substantial amount of evidence.
“It all started when I wanted to buy a really good atlas.
“When I looked at Britain, on the Celtic shelf, between Ireland and Cornwall, there were sandbanks and no-one could understand how they had got there.
“I delved deeper and came to the conclusion that they’d been caused by a flood.
“I started looking at the soil profiles and began to find evidence of collosal flood damage.
“When the ice came down, it pushed down from Scotland and The Lakes, it pushed through the gap between Wales and Ireland, and it all got squeezed together.
“Eventually the lake began to form.
“It would have completely flooded Lake Windermere and when the water receded out of Morecambe Bay it would have left a lot of mud.”
Mr Runggaldlier said that this was one of five theories looking at what happened in the British Isles during the last Ice Age.
