Cornerstone Boulder Rock Climbing
Going for the lip on Cornerstone Lefthand.
This small boulder lies west from Borson's Wall
next to the path on the inside of the bend.
It has some pleasant, although all too short problems, but its definitely worth stopping at.
Park at the San Andreas / Glenwood parking area. Head up the paved road passed the gate. Follow the road / path as it winds its way up the hill. The road heads North, then South and finally swings back North near the crest of the hill. Follow the road until you come to a small bridge. Drop down to the path below and follow this path East / North East. As the road swings left the boulder is on your left.
Weather station 3.3 miles from here

I hadn't visited this area in decades until recently. The route I was taught was not to use the arete, only the small crimps on each face while smearing, then dyno to the top and mantle out. Good times for such a small piece of granite!
