outwash

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

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

Thus arose the type of stratified drift variously known as overwash plains, outwash plains, morainic plains, and morainic aprons.

Good examples of overwash or outwash plains may be seen at various points in the vicinity of Baraboo.
