The park features post-glacial features from the Wisconsian Age (10,000 years ago). These include an esker complex, outwash apron, and a glaciated lake spillway. The bedrock around Kashabowie wears a mantle of glacial till, interspersed with loess -- deposits of fine, yellowish-grey gravel and loam. Bogs, swamps, marshes, forests, and thickets fill in other areas of this natural environment. There are no facilities.
