The prairie is north of the highway.
Vegetation ranges from cattail and sedge wetlands to big bluestem uplands.
Several rare plants and butterflies have been found here. The northern portion was plowed but has been replanted to prairie using seed harvested from this and other prairies in the area. The landscape is characteristic of the Altamont end moraines, an area of irregular knobs and poorly drained depressions. The moraine was formed by the Des Moines Lobe glaciation, about 13,000 years ago. Facilities for this preserve include a designated parking area.
