At North Carolina's home of scary runout slab climbing, Dirty Crack is one of a handful of routes that's well-protected from start to finish. That doesn't mean it's easy; there's some thin moves midway up that might make you want to grab one of the trees growing out of the crack. "Dirty Crack" may have been an apt name in the past, but in fact this is a clean route that's a worthwhile lead.
Starting at the obvious right-facing dihedral, follow the thinning crack up past a couple of trees to the Tree Ledge.
Starts below the far right end of the Tree Ledge at a right-facing dihedral. 10' right of Entrance Crack. Rap on two ropes from rap rings at the top of Father Knows Best or any of the other Tree Ledge rap anchors.
A good range of gear up to 4" (big pieces mainly near the start); there's also trees to sling. Anchor to trees at the top.
Great climb to gain the tree ledge when other climbs like entrance crack, u-slot, and block route are taken. Also, this provides a bit more of a challenge then the previously mention climbs. Tiny gear protects the thin section after the tree.
I agree Emil. It's a shame too because it's really not needed for pro. The crack under the arete right there takes good pro and there is good pro just after the tree as well. I have a feeling though that the beating the tree is taking is as much from people resting on it and using it to hold onto as from slinging it.
