Chimneys State Natural Area

The Chimneys is a 33-acre natural area located in Marion County. It is located in what is commonly referred to as the Pocket Wilderness where Pocket Creek cuts through Cumberland Plateau sandstone forming Pocket Gorge. Pocket Creek has sculpted the impressive features known as the Chimneys over vast geological time. The Chimneys are two isolated, 200-feet high, towering pinnacles of Pennsylvanian Warren Point sandstone connected to a central base. A natural window forms at the base. The pinnacles and natural bridge rise from the gorge floor and are nearly as high as the surrounding bluff. The natural area is adjacent to the Chimneys Scenic Park. It was designated as a state natural area in 1999, the same year it was donated to the State by U.S. Steel Corporation, a subsidiary of Marathon Ashland Petroleum, LLC.
