The Red River Gorge Geological Area and Clifty Wilderness Area of Daniel Boone National Forest and Natural Bridge State Park in east-central Kentucky provide an excellent opportunity to observe and study differential weathering and erosion, mass wasting, and jointing in the development of cliffs, rock shelters, and natural arches. Joints in the study area have varying orientations, but dominant northeast- and northwest-striking orientations are prevalent. Jointing in the study area is related to unloading of overburden and regional tectonic stresses. Unloading joints result from removal of overburden from a rock mass, and orientations of joints are controlled by either residual or contemporary tectonic stresses. The effects of tectonic stresses are evident in joint orientations surrounding the Glencairn Fault.
