The current climbing is on uphill face of large block, but other lines can be found in the area.

There are plenty more lines up there, but these are the best found so far.

As for grades... by the time you visit here, who knows the state of these boulders? The chalk will have washed off, and they might need a good scrubbing. You'll find your best way to climb them, which might not be anything close to the contrivance I posted here. Have fun!

Hike uphill and east of Guano Rock (200 feet). Both are north of FS-360.
