Start: Go left where the trail hits the wall, route begins on a right trending ramp just right of a large tree. p. 1 (5.9, 140 feet) Follow a line of crimps and sidepulls up the steep face to a bolted belay. p. 2 (5.10a, 120 feet) From the belay move up and right (crux) towards a water groove. Make another thin move up towards easier terrain and another two bolt anchor. p. 3 (5.8, 120 feet) Go up and slightly right to a bolt, than traverse left towards another bolt. Keep moving left through a line of weakness on some suspect rock and pull through the roof at a right facing corner, then up to a stance with one bolt. p. 4 (5.7, 80 feet) Make an easy traverse right along a dike, then up grassy ledges to an old tree with rap slings. Continue up and look right for the Out of Towner's rap line.

Descent Options:

Rap with 2 ropes.

4 out of 5 stars Arribas Amoebas

Do every pitch if you want to claim that you climbed this route. The first pitch is a much linger and slightly easier razor crimp fest, like Solid Gold at Jtree. Crux moves on p. 2 are really this but very well protected. Two more traditional pitches create a good adventure feel this this brilliant line.

5 out of 5 stars Excellent route!

Most of the bolts are old buttonheads. Pitch 2 is .10c. For pitch 3, I recommend joining the 3rd pitch of The Out of Towners after the first two bolts of AA to make it a 5 star route.
