Quintin Bendixen, an associate lecturer in the Department of
Geography/Geology at the University of Wisconsin-Waukesha, took the
photograph below at the edge of a glacier
in Greenland. A similar
scene probably was present about 10,000 years ago near what is now the
intersection of Burleigh and Lilly Roads;
it resulted in the sand and
gravel deposit that was excavated from the 1920s to the 1970s.
