The Map of Ice Age Britain

Around 27,000 years ago, in the last ice age, northern Britain and Ireland was mostly covered by ice. The kilometer thick ice sheets that covered Britain had a lasting impact on much of Britain's subsequent geography. You can now explore the ice corridors and glacial lakes of ice age Britain on Sheffield University's BRITICE interactive map.

The BRITICE Glacial Map is an interactive map created by the Department of Geography at the University of Sheffield. The map is built on over 100 years of study into the last ice age including over 1,800 scientific publications. The map shows what Britain looked like during the last ice age. It includes over 170,000 landforms, including moraines, crags, ice dammed lakes and subglacial ribs and lineations.

These different geographical features are color-coded on the map. For example large glacial lakes, like the ones covering Manchester, Doncaster and Peterborough, are colored blue on the map. While, subglacial rib areas, like the one stretching across Northern Ireland and the Republic of Ireland, are shaded yellow.
