Abstract

The Iowan till is not known to be present in Story County. The trend of its southwestern margin which crosses Johnson, Iowa, Tama and Marshall into Hardin County, if maintained with reasonable constancy, would carry it safely beyond the confines of the county. The loess, the silty apron of the Iowan, although suspected to be present on account of the geographic position of the area and of certain topographic contours which are decidedly loess-like in character, was not recognized certainly until during the present field season. The loess is now known to appear at numerous points along the flanks of the deeper cuts in Indian Creek and Collins townships, in the southeastern corner of the county, near the limit of the Wisconsin drift, and there are occasional exposures in Franklin and Washington townships, along the tributaries of the Skunk River and Squaw Creek, in the west central portion of the region. It is to the latter occurrence that it is desired to direct attention.
