Naturalist

Although Split Rock Creek does not have a full-time naturalist on staff, interpretive programs are offered at the park from Memorial Weekend through Labor Day. Check at the park for a schedule of activities or contact the naturalist at Blue Mounds State Park who also coordinates the programming at Split Rock Creek.

Wildlife

Lake and prairie animals inhabit the park. Meadowlarks, beavers, and waterfowl can be seen along the lakeshore. The southern, wooded part of the park is home to woodpeckers, fox squirrels, and other woodland animals.

History

A large dam was completed in 1938 by the Works Progress Administration (WPA). The dam was constructed of Sioux Quartzite, a hard red rock that was quarried locally for use in the building of the dam and nearby highway bridge. The park was developed to provide water-based recreation for an area of the state that has few lakes.

Geology

Three major ice movements during the ice age deposited a thick layer of sand, gravel, rocks, and clay called till, which are several hundred feet in some areas. Under the till lays a hard pink bedrock known as Sioux quartzite. This hard metamorphic rock was quarried in the area for use as a building material.

Landscape

The park is located in the Coteau des Prairies ("highlands of the prairie") Landscape Region. Rock outcrops and shallow soil prevented much of the land within the park from being plowed. However, grazing by domestic livestock has diminished the native grasses and wildflowers. Late summer offers visitors a panorama of prairie colors among the wildflowers and grasses.
