outwash

This outwash plain was a veritable paradise of bloom in the days before the advent of the plow.

From this point north to the Baraboo river the moraine scarcely rises above the edge of the outwash beyond.

Outwash plains are sometimes pitted by bowl-shaped basins where ice blocks were left buried in the sand by the retreating glacier.

In Sauk Prairie, however, its characteristics are those of an outwash plain, rather than those of a valley train.
