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 direction parallel to the edge of the ice mass and are a feature of Northern Central Europe. These valleys, created by glacial meltwaters, do not appear in the Alpine Foreland as they do, for example, in North Germany because their function was assumed by the great rivers that already existed in the region - the Danube, Rhine, Rhône and Po - or their tributaries, which transported away the meltwaters of the glaciers. The Scandinavian ice sheet reached or crossed Northern Central Europe several times. The landforms of the glacial series here thus follow one another from north to south: The
