Esker

 

a long, narrow ridge composed of horizontally or, more often, obliquely stratified sand, gravel, and pebbles and of boulders. Eskers are usually not longer than 40 km but occasionally exceed 500 km. Their width varies between several meters and 2 to 3 km, and their height can reach several dozen meters. Eskers are deposits left by meltwater flowing through valleys and tunnels that have been cut through a glacier. They are found in areas of Quaternary, or Anthropogenic, continental glaciation in Sweden, Finland, and the northern European part of the USSR.


Esker

 

the general name for aggradation glaciofluvial land-forms that formed within glaciers, such as oses, kames, and kame terraces. Some foreign scientists, such as R. Flint, use the term “esker” as a synonym for os.
