Presentation by UIU Professor Katherine McCarville

Geomorphology – the study of landscapes – contributes to our
understanding of the Upper Midwest and the histories of its mighty rivers, the
Mississippi, the Minnesota, the Missouri, and their tributaries. These
modern rivers surround the Iowan Erosion Surface (IES) landform region, with
its enigmatic geomorphology and sediments. Many features of the Silurian
Escarpment and the IES resemble those that have been identified and described
at other locations as subjected to megaflooding related to sudden drainage of
glacial lakes.
Dr. Kathryn McCarville will share her research, including new
interpretations of local geology thanks to advancements in geologic dating
technology, in this fascinating presentation hosted by Clayton County
Conservation. This
program is free and welcome to all ages.
