Despite it's scruffy appearance, all the necessary holds are clean and it's more fun than it looks. Stand start to the right of the arete with a left hand on the arete and your right on a bad crimp. Pull up and pop to the sloper (or use an intermediate crimp) before pressing it out to finish up. Maybe a little sandbagged.
Across the stream from the Zoo, this problem climbs the slightly scruffy face on the left side of the alcove.
