Abstract

The Savanna Terrace composed of alternating red and gray clayey sediments of late Wisconsinan age can be found in five states along the upper Mississippi valley from Pepin County Wisconsin to Jackson County Illinois The terrace is the highest glaciofluviallacustrine deposit without a loess cover in the upper Mississippi valley Chemical physical and mineralogical data show that two different sources provided sediment The red clay is believed to have come from Lake Superior sources while the gray clay is believed to have come from sources farther west Largescale flood events from glacial Lakes Agassiz Grantsburg and Superior were probably the main contributors of the sediments The red clay in the terrace is similar in composition to red glaciolacustrine sediment found in eastern and northern Wisconsin It also is mineralogically similar to the Hinckley Sandstone and the Fond du Lac Formation which occur under and around Lake Superior Radiocarbon dates obtained from the lower Illinois valley indicate that the terrace sediments were deposited sometime between about 13100 and 9500 yr ago Soils developed on the terrace are variable in their physical chemical and mineralogical properties which reflect the composition of the clayey sediments
