Description :
An exceptional stratigraphic and pedologic record of Pleistocene environmental conditions occurs at the Kieler Site in the Driftless area of southwestern Wisconsin. Peoria, Roxana, Loveland, and pre-Loveland loesses overlie weathered bedrock residuum. Rather than nondeposition, the AA. suggest the apparent absence of pre-Illinoian loess units is due in part to erosion, but also to weathering that renders loesses unrecognizable so they are classified as residuum.
