From the lowest point or toe of the butress, climb strait up a 30' slab (no gear). Climb over some loose flakes (thought provoking) to your first gear. Follow features to a crack past a fixed pin (unnecessary) to the bushy overlap. Belay here off gear at a decent stance (5.6+ 120'). Pitch two: Climb strait up, following fun face climbing past 2 fixed pins (unnecessary) to the top. Belay on top, off gear (5.6 100' or so).
Start at toe of the buttress. Climb up. To descend, follow your nose from the top, strait back to a gully. Turn left and follow the gully/chimney to the base.
