Geologic features include excellent Silurian dolomite cliffs. Both Greenfield dolomite and Peebles dolomite are exposed. Ohio black shale occurs on the tops of the knobs. An impressive fault, causing vertical displacement of 30 feet, exposes adjacent cliffs of Greenfield and Peebles dolomite.
The preserve's dolomite cliffs provide habitat for white cedar and sullivantia. American aloe, dwarf hawthorn, hairy wing-stem, side-oats gramma grass and purple coneflower are found in the prairie openings. Other significant species include tall larkspur, limestone Adder's-tongue fern, narrow-leaved bluecurls and Walter's violet.
