Abstract

A review of bedrock topographic mapping of Iowa indicates that less than half of the state has been mapped. A map compiled primarily from the published literature of the bedrock configuration of Iowa and segments of the adjacent states of Minnesota, Illinois, Missouri and Nebraska suggests that the bedrock valley pattern parallels modern drainage as hypothesized by Kay and Apfel, in 1928. An unpublished map by Hale (1950) captured major valley trends remarkably well for the limited amount of data available. Studies of the bedrock surface by the United States Geological Survey in cooperation with the Iowa Geological Survey and by the Hydrogeology Research Group at Iowa State University are presently being conducted.
