We are fortunate that northern Wisconsin is one of the most geologically stable regions in the United States—far from any volcanoes or earthquake epicenters. However, this was not always the case. In the distant past incredible convulsions rocked the Earth’s crust, creating such features as the Penokee Range and Lake Superior that we all know and love. Professor Mike Heim will take us on a tour through billions of years of Wisconsin history; from continents colliding to continents being torn asunder, from sandy ocean beaches to mile-high ice sheets. 7:00 p.m. at the Museum.
