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
Puyehue Lake "Llobén", from the Huilliche word of "llofën" meaning "abundant and continuous rain." Puyehue Lake Puyehue Lake (), (Mapudungun: "puye", "small fish" and "hue", "place") is an Andean piedmont lake on the border of Los Lagos Region with Los Ríos Region of Chile. Puyehue is a lake of glacial origin. Several times during the Pleistocene glaciations, the lake depression was occupied by a large glacial lobe of the Patagonian Ice Sheet, which formed a series of moraines along its western shore. The lake has an east-west elongated shape with Fresia Island in the middle and two minor peninsulas pointing toward the
