The rich soils of the area are part of the glacial till plains of western Ohio. Early settlers cleared the dense woodlands to farm the fertile soil. Nearly all of Ohio’s original forest has since vanished. However, one unique stand of virgin timber remains at Hueston Woods. Over 200 acres have been protected and provide visitors with a glimpse of Ohio’s primeval forest. Stately beech and sugar maple tower above the abundance of ferns, wildflowers, and other woodland species. In 1967, the 200-acre forest was designated a National Natural Landmark by the National Park Service.

Hueston Woods State Park located in southwest Ohio has an enormous wealth of natural resources. The limestone bedrock of the area is evidence of an ancient shallow sea that once covered Ohio. Much of the limestone is the magnesium-bearing type called dolomite. Fossilized remains of ancient marine animals are so abundant that people from all over the world come to Hueston Woods to collect them.
