Clarks Knob is a summit in Franklin County, Pennsylvania.[3] It is the highest point on Blue Mountain, the eastern front range of Pennsylvania's Ridge and Valley Appalachians region.[2]


Clarks Knob's northeast-southwest running summit ridge forms the boundary of the Susquehanna River and Potomac River drainages.[2] It stands over 1,600 feet (488 m) above the town of Chambersburg and the Great Appalachian Valley. This mountain is protected within the Buchanan State Forest.[2]
