The Prow and the North Wall are on the West side of the canyon. Just before the road dead ends, there is a pullout on the right. A short trail takes you through the willows and across the creek via a couple of foot bridges. After crossing the creek, the trail branches. The right fork takes you uphill to The Prow and the North Wall. The left fork follows the creek down canyon to more climbing.
Climbers can minimize impact by staying on the established approach trail, as indicated by the topo.

There is a new route to the right of Natural Born Drilla. Does anyone know what it is rated or who put it up? Very fun line.
