Nelson-Kennedy Ledges, Garrettsville, Ohio, is popular for picnicking and hiking. The rock formations at the 167-acre (0.68 km2) Nelson-Kennedy Ledges have become trademarks of the park. The sandstone cliff formations resulted from the forces of erosion—wind, water freezing and thawing—that wore away at the softer rock layers. As these soft layers eroded, large blocks of rock called slump blocks fell away leaving more resistant layers to form ledges above. Within the park are angled rock formations 50 to 60 feet (18 m) high with ground fissures as deep as 60 feet (18 m).
