Sandstone Towers In Wisconsin

Summary authors & editors: Jim Foster; P. Riemer
The photo above was taken earlier this month near Douglas, Wisconsin and shows a sandstone castle rising from what was Glacial Lake Wisconsin. This particular formation is adjacent to a picnic wayside on the north side of highway I90-I94. Isolated sandstone crags, which are formed by weathering and the work of wind, are outliers of a former larger escarpment -- the more resistant rocks have been left behind and are still being eroded. In portions of southwestern and south central Wisconsin, there was an absence of glacial deposition, and thus geological features in this area are not a result of the affects of glacial scouring and or recession.
