Start on the far left edge of the Challenger Wall. Up a thin crack to a small ledge where you will move left to gain the right edge of a flake system. Up through this flake system on some small gear and delicate moves will get you to the roof. Jam and undercling out left, and pull the roof. From here a nice low angle crack will get you to a two bolt anchor.
This route is the left most route on the Challenger Wall.
Single rack to #3 camalot, double small cams.
