Abstract

When a stratified, loess-like gumbo, occurring along the Missouri River above Council Bluffs, was first described by Bohumil Shimek, and named by him the Loveland loess, it was thought by him to be a fluvio-glacial deposit. Such gumbo-loess since turned out to be really a lacustrial deposition, wind-blown dusts, from the dry plains and southwestern deserts, laid down in local bodies of water, or ponds. In the description of the Loveland exposures Shimek unwittingly gives key to its age and stratigraphical setting, that is quite different from what he surmised. A layer of widespread, volcanic ash intersects the section on the Missouri River which shows that the Loveland beds were deposited immediately before the culmination of the Ashawa (Late Wisconsin) ice advance.
