Lake George with Mammoth Mountain in the distance,...


This awesome granite crag is located above the Twin lakes in Mammoth and features great summer cragging on quality rock with breathtaking views. A large snowbank can make climbing on the North face difficult until late in the season.

Getting There 

Take highway 203 to the stop light at the Village. Continue straight on Lake Mary Road. Follow this to the left turn at the Pokonobe Lodge. Take a right at the "T" and continue up to the Lake George parking area. Hike around the right side of the shore line to the opposite side of the lake. Then head up the hill on a climbers trail to the cliff.

Hey there,
Left my GriGri 2 up at the base of Black Leather (11a dihedral) on Aug 10th.

Went up there a few days later and not to be found. If you happened to pick it up I would love to get it back thanks!
