4. Bad Faith 5.9
5. [[10573994...
Located in a National Forest Fee Area MORE INFO >>>


North facing, jug hauling, blitz-krieg limestone. The Membrane hosts some of AF's finest sport routes, and on most days the crag will have someone on one of them. The Membrane is the perfect crag for busting out of Boulder and jumping on a pump-fest before you even set up the tent. With zero approach, good stone, and a wide range of difficulty to pick from, The Membrane is hard to beat. Warning: these routes are not grid bolted, so be prepared to run for the clips on most routes.

Getting There 

Park at the pull-out 1.0 miles from TCNM. The Membrane is immediately across the stream, behind the trees.

See here for a Google Street View photo of the parking area.

Route 66 5.12a 7a+ 25 VIII+ E5 6a  UT : Wasatch Range : ... : The Membrane
Just left of License To Thrill is a stiff problem that fires up to the left side of a roof. Route 66 has pumpy, fingery climbing on small pockets and edges. Crux was a bit below the roof and needed good contact strength - seems like you are always on your arms. The roof sequence is described as bizarre in the Ruckman/Ruckman guide. Tricky yes, with an overhead bolt to start, but it runs out once you stand up over the roof. Definitely worth a burn....[more]   Browse More Classics in UT
