This route is amazing. The crux is on the second pitch. For 5.8 it is very exposed but well worth the hike and effort. I can't say that there is anything bad about this route. To find the route look for the "tallest and most prominent clean rib/buttress on formation." There are two sets of double cracks that divide the west face of this rib. P1. (5.6) Climb right through the middle of the buttress along a beautiful 2' wide groove ending on an ample ledge. Build own anchor (50'). P2. In this superb pitch, follow the righthand set of double cracks past two small overhangs (crux) then end at the top of the rib (150').
Location
Sparerib is its own formation. Descent: Walkoff either side of the buttress.
