Bio-Degradable

Start 5 feet right of arete, 10 feet left of Organic Matter. Climb to base of tree, pass to the right and follow crack to the top. Stay left of the chimney with the pine tree, making use of the arete and toping-out inline with the arete.

First wall as you enter the hollow.

I used small to medium sized nuts and hexs. Last horizontal crack would be protected easy with a cam.
