Glacial lake Glacial lake A glacial lake is a lake with origins in a melted glacier. They are formed when a glacier erodes the land, and then melts, filling the hole or space that it has created. Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. This is apparent in the Lake District in Northwestern England where post-glacial sediments are normally between 4 and 6 metres deep. These lakes
Glacial series Glacial series The glacial series refers to a particular sequence of landforms in Central Europe that were formed during the Pleistocene glaciation beneath the ice sheets, along their margins and on their forelands during each glacial advance. The term "glacial series" () was used as early as 1882 by Albrecht Penck initially for the northern Alpine Foreland. Later the term was expanded and used to refer to the Scandinavian glaciation region. The elements of an ideal and complete glacial series are: The term "glacial series" is restricted to landforms created by glaciers and classified by geomorphological rules, as opposed to
