Freda Haffner Preserve displays a landscape formed during the slow melting of stagnant glacial ice. The Prairie is covered by dry and mesic prairie, wetland, and hayfield. From Iowa 86 and U.S. 71 north of Milford, IA, take Iowa 86 west. Continue west on gravel where Iowa 86 turns north. The preserve is about 2 miles west of Iowa 86 on the north side of road.
