On the SW face, left of the big roof is a rotten-looking (but solid) white looking face. There are 2 routes that are bolted here. This is the left one. Climb up the crack to attain the ledge where one can clip the first bolt. Continue up this steep face to the chains. Lots of crimpers, and good footwork. With only the occasional reachy move. Good workout.
Protection
2 bolts are at the top for anchors, and 4-6 draws for the climb. A small selection of medium gear will protect the moves up to the ledge.
Did this yesterday, and there were still a few sluggish wasps on the mineral deposits! I did like this climb, it really catered to my style of climbing, so for me; felt easier than 11a. A good route.
