Dardanelle Rock Natural Area, located in the Arkansas Valley, contains an exposure of Hartshorne sandstone that was folded into a synclinal (concave upward fold) structure when the Ouachita Mountains were formed and then breached through erosion by the Arkansas River to form a water gap. Dardanelle Rock has been a major landmark along the Arkansas River since the days of early Arkansas exploration. Parts of the outcrop are naturally devoid of vegetation; however, some slopes hold enough soil to support a forest of black oak, mockernut hickory, and shortleaf pine.
The site is located on the east end of Dardanelle Mountain at Dardanelle, Arkansas. To access the area, turn north off state Highway 7 onto Front Street. Proceed 1 mile to the natural area sign.
Hunting is prohibited on this natural area.
