Stinchcomb-Groth Memorial, a 30-foot tower made of cinder block and sandstone, was dedicated in 1958 to the first two directors of Cleveland Metroparks, William Stinchcomb and Harold Groth. Together, these two men were responsible for establishing 18,000 acres of parkland and 84 miles of parkway. Follow the nearby River Overlook Loop Trail for a beautiful view of Rocky River Valley. Wander along the path to the overlook and gaze down at the first Cleveland Metroparks land purchased a 3.8 acre parcel purchased in April 1919 currently located under the Hilliard Road Bridge.
