Heggie's Rock, National Natural Landmark in Columbia County, Georgia, United States

Heggie's Rock is a granite outcropping of about 130 acres in Columbia County, Georgia, roughly 20 miles from Augusta. It rises about 70 feet above the surrounding land and is bordered by two streams, Benton Branch and Little Kiokee Creek. It is one of several large granite outcroppings in Georgia, alongside Panola Mountain, Stone Mountain and Arabia Mountain.

The area was designated as a National Natural Landmark in 1980 and later acquired by The Nature Conservancy to protect its ecological features. This led to scientific research that revealed the site's importance for rare species.

The 101 acres bought by The Nature Conservancy in 1983 form Heggie's Rock Preserve, one of several large granite outcroppings in Georgia alongside Stone Mountain, Panola Mountain and Arabia Mountain. The rock lies about 20 miles from Augusta, between Benton Branch and Little Kiokee Creek, which reaches the Savannah River some 8 miles downstream.

The preserve lies about 20 miles from Augusta, with the granite rising roughly 70 feet above land bordered by Benton Branch and Little Kiokee Creek. The Nature Conservancy bought 101 acres in 1983, so check with the Conservancy for current visiting arrangements before travelling. The nearest large granite outcrops for comparison are Stone Mountain, Panola Mountain and Arabia Mountain.

In 1998, scientists described a new genus and species of copepod found only at Heggie's Rock, a tiny crustacean living in the shallow pools on the granite. It remains known from this outcrop alone, which is why the site is studied as well as visited.
