This is not a bad line. The corner indeed looks dirty at the bottom, and it is. However, the actual climb is up the splitter to the right of the corner, not up the dirty corner itself. The lines merge just as the rock cleans up, making for not too bad a climb.
Start off in the thin-hands crack just right of the right side of the deep inset, left of Crooked Cross. The start of which would be much harder were it not for the corner you can stem to just to the left. Continue to the excellent flake where that ends and work up and left into the corner. A slopy crux comes just after good gear, then one can wander on up on larger holds to the juniper again.
To descend, walk up and back off of the top, then down to the West and around to the base of the cliff.
This climb is just left and around a corner on the 'Crooked Cross' ledge. One can approach similarly to Crooked Cross, or rap from the juniper above that down into the corner and then climb back up to the top.
A single set of cams to 3" and a few stoppers.
