Abstract

During the progress of the soil survey of Jefferson County, Iowa observations of the Kansan gumbotil and the overlying loess have revealed a limited number of locations in this county and in adjacent Van Buren County in which there is a very uneven boundary between these two materials. This deformation of the gumbotil and loess contact appears to be attributable to periglacial conditions prevalent during a part of the Pleistocene.
