WebOutwash plains : Also called a sandur, an outwash plain is formed by glaciers. Such a plain is formed when a glacier deposits sediments at its terminus. As a glacier moves, it erodes the bedrock and carries the eroded sediments downstream. These sediments are deposited by the meltwater of the glacier at the snout.
