McConnells Mill State Park, in Lawrence County, encompasses 2,546 acres of the spectacular Slippery Rock Creek Gorge. Created by the draining of glacial lakes thousands of years ago, the gorge has steeps sides and the valley floor is littered with huge boulders. A gristmill was built in the 1800s to harness the power of the water. The park is open from sunrise to sunset, year-round.
