Online map shows grip of Ice Age on UK

An interactive online map showing how cities were affected by the last glacial cycle 22,000 years ago, when a half mile-thick sheet of ice covered Britain, has been unveiled by researchers at Sheffield University.

Dr Jeremy Ely, of the university’s geography department, said: “The landform information tells us about how the last British-Irish ice sheet behaved. We can see how it dammed rivers, creating large glacial lakes which covered Manchester, Doncaster and Peterborough.

“Corridors of fast flowing ice, flowed toward the east over Edinburgh and toward the west over Glasgow. Ice also covered Ireland, flowing through the Irish Sea, where it coalesced with Welsh ice, causing it to flow southward to the Isles of Scilly.”

The map is the result of six years’ work by researchers.
