Glacial boundary

A glacial boundary is a line on a map representing the farthest advance of a glacier that has retreated. It generally refers to the extent of continental, rather than alpine, glaciers.

In the northern hemisphere, glaciers advanced from the north during the Pleistocene epoch. The glacial boundary thus represents the farthest southern extent of the glaciers at that time.
