About the Event

     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.

If you are unable to attend this event in person we will be allowing people to join via Zoom. Here is the meeting information:
