Start with right hand on triangle hold near the tree (same start hold of Slow Vibration) left hand on the rail. I use the the big shelf for feet and then traverse up and left via sloper pods and crimps. Grab small edge over lip and side pull out left to rock over onto the slab and top out.
On the outside of the Chasm boulder, facing south. To the left of the tree. Downclimb an arete/chimney into the Chasm to get down.
Pads and a spotter to keep you out of the leaf and toad filled hole.
