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 model of the glacial series. A common variation, for example, is the spillage of younger meltwaters over older ground moraine beds. In addition, a further advance of the glacier can result in the interlacing of various older landforms of the glacial series. For example, lines of terminal moraines lying close behind one another in the Brandenburg region of Germany drained over the same sandurs and via the same meltwater valley. 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
