Hands-on discovery center encourages guests to explore animals and ecosystems found in the Great Lakes and beyond. Visitors experience the geologic forces that shaped Lake Superior, watch as divers feed fish in a massive two-story tank, raise and lower locks on a scale model of the Great Lakes, pilot a virtual ore boat under the Aerial Lift Bridge and pet young sturgeon and freshwater stingrays. Exhibits showcase over 70 species of fish, birds, reptiles, amphibians and mammals providing a unique window into watery worlds.
