Walk up Rattlesnake canyon for 30-45 minutes. Take a trail to the right near a three pronged tree and evade the copious amounts of poison oak invading the trail. walk up the other side of the canyon and at the first switchback you'll see a side drainage and up that the boulder.
Large overhanging face lurking back behind the trees when approaching on the trail. Climb the right arete using heel hooks and a useful face hold. A hidden right hand crimp allows you to jump for a jug at the very tip of the prow, proceed to mantle (spicy) on said jug and take it to the top! Perhaps climbed in the past...
Pads, moderately good landing
