Book Description
Excerpt from Groundwater Geology of Lee and Whiteside Counties, Illinois Stratified bedrock formations consisting of dolomite (a limestone-type rock), shale, and sandstone occur below the drift throughout the counties. The top Of the buried rock is not smooth because for mil lions oi years it was exposed to the same forces of erosion as the present land surface. The bedrock surface has its own uplands and valley lowlands. These ancient buried valleys in many cases contain large water bearing sand and gravel deposits. Enor mous reservoirs of groundwater occur in such buried valleys as those Of the ancient Mississippi and Rock rivers. The courses of these abandoned and buried valleys bear little relation to the river courses on the present landscape.
