Beachcombing for rocks along the shores of Lake Michigan is not only fun, but also serves as a study into the geologic story of the Great Lakes region. Discover how sedimentary limestone containing fossils indicate that the Midwest was once a tropical ocean; and the igneous and metamorphic rocks show the movement of glaciers during the Ice Age. Join Dave Dolak for this presentation to better appreciate your next stroll along the beaches of Lake Michigan.
