The northern end of Wills Mountain is known as [[Kinton Knob]] and is the crest of a plunging [[anticline]]. The [[Silurian]] [[Tuscarora Formation]], a hard [[sandstone]], outcrops at the crests of these ridges and is [[stratigraphy|stratigraphically]] lower and thus older than the rest of the [[bedrock]] in the township. The overlying formations are either Silurian or [[Devonian]] in age, and include (in ascending order) the [[Clinton Group]], the [[Bloomsburg Formation]], the [[Mifflintown Formation]], the [[Wills Creek Formation]], the [[Tonoloway Formation]], the [[Keyser Formation]], the [[Old Port Formation]], the [[Onondaga Formation]], and the [[Hamilton Group]], which is composed of the [[Marcellus Shale]] and the [[Mahantango Formation]]. The [[Ridgeley sandstone|Ridgeley Member]] of the Old Port Formation, another sandstone and [[conglomerate (geology)|conglomerate]], forms the low ridge in the center of the township south of the town of Bedford, as well as Stiffler Ridge in Dunning Cove. Dunning Cove itself is a [[structural basin]].<ref>Berg, T.M., Edmunds, W.E., Geyer, A.R. and others, compilers, (1980).
