Eskers Eskers are long, curving ridges of stratified sediments found in previously glaciated regions. They may be several meters to hundreds of kilometers in length. The height and width of an esker are determined by the water and ice pressure and sediment load at the time of formation.Bridge, John; Demicco, R. Earth Surface Processes, Landforms and Sediment Deposits. (Cambridge University Press (CUP), 2008). Eskers form in ice tunnels within or under a glacier  and are composed of the sediment deposits from the streams that occupy these tunnels.Shreve, R. L. Esker characteristics in terms of glacier physics, Katahdin esker system, Maine. Geol. Soc. Am. Bull. 96, 639–646 (1985). Eskers may also form from supra-glacial streams that cut into the crevasses of the glacier. After the ice has melted away the stream deposits are left remaining as long mounded eskers. A system of subglacial streams may create a branched formation of eskers, although these are not often continuous branches. 370x370px| Esker Formation: On the left, meltwater streams deposit sediments in a subglacial meltwater tunnel. On the right, the presence of a fully formed esker after the retreat of the glacier.
