Abstract

In the excavations of the new primary road cuts during the past three years many cross-sections of the soils of southern Iowa have been exposed to view. One zone of soil which is particularly noticeable occurs overlying the Kansan till. The zone is a light-colored layer and the leached or unleached loess, as the case may be rests upon it, while the gravels of the Kansan, with few exceptions lie under it. The reddish ferreto zone in connection with these gravels gives a contrast in colors which makes the light colored zone easy to distinguish in the cross-sections along many fresh road cuts. In all cuts examined the gravels and the upper part of the till show oxidation.
