Escher's are glacial features formed when meltwater streams underneath a glacier, creating tunnels and channels that can collapse to form depressions on the glacier's surface. These features can disrupt or alter the glacier's flow and structure.
Some features formed by glacial deposition include moraines (ridges of till), drumlins (elongated hills), eskers (sinuous ridges of sand and gravel), and kettles (depressions formed by melting ice blocks).
Cirques are bowl-shaped depressions formed by glacial erosion at the head of a glacier. Arêtes are narrow ridges that separate two adjacent glacial valleys. Roche moutonnées are glacier-smoothed bedrock outcrops with a gentle up-glacier slope and a steep down-glacier slope.
glacial lakes. These lakes were formed by the meltwater from the ice blocks, and often occupied depressions in the landscape created by glacial activity. They were temporary features that eventually drained as the ice melted away completely.
Some glacial deposition features include moraines, drumlins, eskers, and outwash plains. These features are a result of the deposition of sediment and rocks carried by glaciers as they move and melt.
Glacial spillways are formed when meltwater from a retreating glacier creates a pathway through moraines or other glacial deposits. As the glacier retreats, the trapped water is released, carving out a channel that can carry large volumes of water downstream. These spillways are important for draining glacial lakes and preventing catastrophic flooding.

The features that are not a result of a glacier carving out rock include sedimentary layers formed by water deposition, such as deltas or riverbanks. These formations are created by the accumulation of sediments transported by water rather than by glacial activity. Other non-glacial features might include volcanic formations or man-made structures, which are unrelated to the processes of glacial erosion and movement.
