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 to the margin of the ice sheet, mostly in a northwesterly direction. Meltwater valleys are a special landform in Northern Central Europe. Like all models, the model of the glacial series gives only a simplified picture of the real situation. In particular, it is often forgotten that the landforms of the glacial series were formed almost at the same time alongside one another, whilst the ice margin remained static by the terminal moraine. Furthermore the ice then had to advance as far as the later terminal moraines and then melt away again. The processes that accompany that, clearly alter the
