Ray Wiggers, author of the popular earth-science guidebook Geology Underfoot in Illinois, presents an illustrated lecture on Illinois' surprising geologic history. From downtown Chicago to the river valleys of the central counties, and from the canyons of Galena to the soaring cliffs of Shawnee National Forest, these compelling images will prove that Illinois is anything but flat and boring!
