The ridge line separates Kishacoquillas Valley from the Seven Mountains area.
Stone Mountain lies in, and the ridge line forms part of the border between, Mifflin and Huntingdon counties.
Pennsylvania Route 305 crosses the ridge and follows a valley along a fault line at 40°37′46″N 77°45′31″W / 40.62944°N 77.75861°W / 40.62944; -77.75861 near Greenwood Furnace State Park.
Allensville Road also crosses the ridge crest north of Allensville, and Barrville Road passes through a wind gap west of Barrville.
Just below the ridge crest lies the contact between the older Ordovician Juniata Formation on the southeast slope, and the younger more erosion resistant Silurian Tuscarora Formation geologic layer forming the steeper northwest slope and the crest.
