Ice Age Scotland
20,000 years ago Scotland, like much of the Northern Hemisphere was blanketed by a great ice sheet, over 4000ft thick in places; and the effect on our landscape of this event is huge. Ice ages occur in part because of astronomical cycles, and over the course of the last two million years the ice has waxed and waned over Scotland. The last 10,000 years have been warm and ice free, but the legacy of the glaciers upon our scenery and history is incalculable.
