Learn all about mammals in Iowa! It's easy to learn about mammals when you get to touch and see skulls, furs, and tracks firsthand. Also, we will go on a hike and learn how to look for signs of mammals, and possibly even see one along the way! At the North Overlook Beach playscape, 7 pm, free. Contact the Corps of Engineers with questions at 641-628-8690. May be cancelled if inclement weather.
