Good examples of overwash or outwash plains may be seen at various points in the vicinity of Baraboo.
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.
In Sauk Prairie, however, its characteristics are those of an outwash plain, rather than those of a valley train.
A good example of an outwash plain occurs southwest of Baraboo, flanking the moraine on the west (Fig. 41).
From this point north to the Baraboo river the moraine scarcely rises above the edge of the outwash beyond.
outwash plains are the deposits formed by streams which, during the Ice Age, issued from the glaciers.
outwash plains are sometimes pitted by bowl-shaped basins where ice blocks were left buried in the sand by the retreating glacier.
