Purple Stripe

Climb up the set-back to the ledge, or climb a crack on the right and hand-traverse left to the ledge (more contrived, but more fun moves). Step up on a decent foothold out on the face, and work your way through a serious of strenuous small holds up the seam to the top. Clever footwork pays dividends here.

The main portion of White Wall hosts a couple of 12's, and "Purple Stripe." On the left side of this sweep of rock is a square cut set-back with a ledge/alcove on its right.

Gear to 2" for the lower part. Gear from 1/8 - 1/2" at the crux. It's actually possible to get 3-4 pieces in, if you have enough small gear and the patience to hang out and place it.

Although there is gear, it requires precision to place it well, so I'd still call this route PG13.
