This has several 3 star sport and trad routes. The rock and routes are similar to Yosemite. These slabs face south, and this area is nice in the cooler months. It is best to rappel routes from 2 bolt anchors at the top of each route or from trees. "Panic in the Grey Room" (5.10a) is a definite must do route, along with "Emergency Entrance" (5.6).
Go 5.1 miles up the canyon, use pullout on the left (best to drive a little further and turn around at the turn off to the Forest Service Ranger cabins). Infirmary Slabs (Upper and Lower) are on the north side of the road. Hike up the steep trail to the right and work your way up and past the Lower Infirmary Slabs, and continue hiking and scrambling west and north. Be careful of poison ivy as it is plentiful up here.

Yes, several climbs have been established above Upper Infirmary Slabs. There's a leaning slab (with obvious leaning crack, 5.7) above and right (about 150') from the top of Emergency Entrance's right hand finish. Above that is a small dome with a nice 5.9 crack on its right side (short pitch, and followed by another short pitch up a thin crack). There's a larger block above that with at least one route on it: look for some shiny chains above a left-leaning crack on the east side (an old 5.9 route that had a fixed #9 hex for a rap anchor when we did it; we added a modern rappel station). Walk east a short distance from the base of the "#9 hex crack" and you come to a drop off -- the cliff below has two routes on it. Left route is a neat hand jam behind a flake (5.10), and the right one begins with an overhaning fist crack leading into a chimney. Bolt rap station on top of the wide crack allows access from above (rope up to approach the bolt station from above, or risk a 50 foot fall to an untimely death amongst boulders). The wide crack has yet to be free climbed in good style. Probably 5.12a fists at the bottom, and a 5.11 crux at the top.
It wouldn't surprise me at all to learn there have been other climbs established on that upper band of rocks above Upper Infirmary, but these are the ones I'm aware of.

I noticed a set of shuts high on the buttress between the left and right slabs. Probably 20' above the tree for Emergency Entrance but you can't see it except from the shuts above Panic in the Grey Room. I don't see any other bolts up the buttress, but it looks like an interesting (and hard) line. Unless my heat-dazzled eyes are playing tricks on me... Jul 11, 2005
