Black Rock Mountain State Park
Black Rock Mountain State Park is a 1,743-acre (705 ha) Georgia, United States, state park west of Mountain City in Rabun County, in the Blue Ridge Mountains. It is named after its sheer cliffs of dark-colored biotite gneiss. Astride the Eastern Continental Divide at an elevation of 3,640 feet (1,110 m), the park provides many scenic overlooks and 80-mile (130 km) vistas of the southern Appalachian Mountains. On a clear day, four states are visible: Georgia, North Carolina, South Carolina, and Tennessee. In addition to Black Rock Mountain itself, the park includes four other peaks over 3,000 feet (910 m) in elevation, making it the state's highest state park. As of 2019, it was open to visitors year round.
Most of the rock outcrops found throughout the park are made of biotite gneiss, a metamorphic rock that underlies a large portion of the Georgia Blue Ridge. Black Rock Mountain State Park was established in 1952 and originally consisted of 1,000 acres (400 ha). Before the park was established, Rabun County native John V. Arrendale began assembling the area that would later become the park, making his first 70-acre (280,000 m2) purchase in 1938. Numerous purchases have added to the park's area, including 301 acres (1.22 km2) added in 1995 with funding received from then-Governor Zell Miller's Preservation 2000 land acquisition program. Several smaller acquisitions have added acreage to the park's southwest corner.
