Description Suggest change

"The Mouth" is the common named used for the two massifs at the mouth of Clark's Fork Canyon. These impressive slabs are composed of Madison Limestone and can be up to 3,000 feet high. Geologically these slabs are not created by exposed faulting, but actually by the slabs being tilted upward by the lifting of the Yellowstone Plateau. This makes for very solid rock for very large sweeps of the massif. If your idea of climbing is less than half a rope length off the ground with lots of dynos and swinging on your arms, you might not like it here. However, if you like to move real fast  and way off the deck, this is your place. These are among the longest bolted climbs in North America. 

Getting There Suggest change

Clark, which is more of an area than a town, is about 25 miles north of Cody and 7 miles south of the Montana border on Wyoming Highway 120. Drive there and turn west at the Edelweiss Restaurant on Canyon Road 1AB. Trend left on route 8vc after a couple miles and follow it until the mouth of the canyon. The north massif is pretty hard to miss as you approach. Walk a quarter to half a mile from the highway, crossing a BLM fence, to reach the routes. Wild camping can be had on the BLM land on the south side of the highway near the river.
