This paper is the result of an attempt to determine, if possible, the relation of the Wisconsin drift to the Iowan drift, not only along the immediate border of the Wisconsin drift, as outlined in the Iowa State Geological Survey Reports, but within the Wisconsin drift plain itself. A careful and detailed investigation was made along the eastern border of the Wisconsin drift from the northern boundary of Worth County, where the eastern edge of the Wisconsin drift enters the state, as far south as Hardin County. Examination of drift cuts, well logs, and a recently excavated coal shaft, located in Hardin County on the border of the Wisconsin drift, failed to reveal, in any positive way, the presence of Iowan drift beneath Wisconsin drift.
