The park is set in a rolling glacial moraine and bluffland. It contains a combination of oak openings and woodlands. The forests combine upland hardwoods with some pine plantations. Remnant prairies are being expanded and oak savannas are being restored through an aggressive resource management program that makes extensive use of volunteers. Park wildflowers include prairie pasque flowers and woodland ephemerals in the spring; butterfly weed and puccoons on the summer prairie; and sunflowers and blazing star in the fall.
