Description :
The Peoria Loess of south-central Nebraska, deposited approximately during the Last Glacial Maximum, can be subdivided into three zones: an upper laminated loess and a lower massive loess, separated by a dark gley zone in which bison bones and spruce charcoal are found. The AA. measured laminations, color and texture, distribution of carbonate nodules, and presence of fossil plant debris. Discussion of the results of magnetic susceptibility measured on 330 samples from the three sections.
