Our Stubb’s Eddy bus tour will take us back in time to the former site of the “Great White Swan” cave on Rock Island, followed by a visit to the nearby Corps’ Mississippi River Museum for a private viewing of their rare collection of Henry Bosse river prints, which capture the untamed Mississippi River before locks and dams altered it forever. To revisit our unique geological past, we will tour Augustana College’s “Fryxell Geology Museum,” -- one of the most outstanding in the Midwest. (Named after the former Augustana professor, Fritiof Fryxell, the first U.S. Park Service Naturalist, who laid out the trails for Grand Teton National Park.) Visitors entering the museum’s 2-story lobby will be greeted by a 22 ft. long skeleton of Cryolophosauris, a carnivorous dinosaur discovered in 1991 by current Augustana professor and world famous Antarctic paleotologist, William Hammer. The museum is filled with a spectacular assortment of crystal, mineral and rock displays, a black light show, and fossil exhibits which unlock the secrets of our unique geological past here on the notorious Rock Island Rapids.
