Baker smashing Corrugation Corner.

Reopened after flood damage! MORE INFO >>>


This route is located at the far end of the ledge system that runs beneath the north face of the Pinnacle. It goes up an obvious arete that is a few feet left of the Army Route corner system. The start has some friable rock, but the climbing quickly becomes very good. The crux is looking for tricky holds while trying to pull a bulge and switch side of the arete at the same time. Enjoy.

Great route for a warm up. Pulling the bulge is rather simple if you know how great the hold is to the left of the arete. This climb without any beta on that hold would make it rather difficult, but with knowledge of that jug it puts this climb in the 5.9+ range. The aforementioned hold is also very chalked up so its not hard to find. Except for the bulge move, this route would probably go at 5.8 due to its slabby nature. One of the must dos in the canyon.
