I think the old guide book put this at 5.8 and the new one has it at 5.8+. If you have trouble hand jamming and don't know how to smear, it will feel more like 5.9.
P1: Follow the left-arching finger crack past a roof and up to a belay ledge. There is an anchor just before the roof but don't stop there, it's cheating! Finish by turning the corner and heading up to another set of chains. 5.8+, 70'.
Location
50' right of Bonnie's Roof at a left-facing corner.
I have no trouble hand jamming or with corners, but I still call Groovy 5.9. The initial corner is quite straightforward, and is not the crux. Moving up into the traverse, and getting across it, is steep (and awkward) climbing on a few not-so-great feet, until you've moved past the sling salad. These moves add up to 5.9.
Carefully inspect the sling salad rap station above P1: there are sharp edges in the constriction that's slung, and over the years I've seen it saw through a few slings. Hopefully the Preserve will add bolts here eventually, as this is an objectively more dangerous rap station than many others.
