Sandr

(from Icelandic sandr, sand), areas composed of sand and gravel, adjoining the margin of a glacier. Sandrs are extensively developed on plains where continental glaciation occurred in the Quaternary period. They are flat cones, joined at the margins, formed from the debris of subglacial streams. Sand sandrs without vegetation often become fields of continental dunes. The Pripiat’, Meshchera, and other Poles’e regions in the European USSR are extensive sandrs.
