The methlab is the most obvious formation in the area. Look for the huge overhanging prow which is visible from the road. The back side of this boulder (and its surrounding formations) hosts many classic routes including Octurnal.

Follow the main trail from the road for about 75 yards, turn left just before "the good". The first route that you will encounter approaching from this direction is "Leave it to Jesus", if you scramble around the tree to the right you will end up in the Octurnal sanctum where most of the other routes are located.
