Climb up onto the small foot slab and gain a nice, fat, hueco-like pocket. Work your way straight up the steep face via a sweet, left-handed, vertical corner (the rail). Keep working the side pull for all it's worth then at the moment of truth... crux your way to the safety of the top.
From the first parking lot hike the Sisters Trail (Staying right of "The Brothers Lookout"). Continue just past the "Pachyderm Boulder" where you will began to head LEFT or (WEST) up hill into a slowly tightening gully. The first major boulder that should come into view will be the Marmot Block. Once you have found this boulder all the other currently established lines can be found just a little further up hill to the NORTH/WEST.
Pads and spotters.
