Mainly sport routes on a south facing slab. Nice location during cooler months. Several bolted face routes, Ratings in the climbing guides are way SANDBAGGED. Routes can be top roped or sport lead.
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 Be careful of poison ivy as it is plentiful up here.
Just uphill the first level above the lower slabs, on the left side between two big blocks is a 12' finger crack that is short but sweet. It goes at 5.9- "Short but Sweet" done 7/21 by Bill Morris and Pebby Johns. To get to the crack, simply follow the trial around the left side of the slab and scramble up and to the left and you should see it.
I spent a while hiking through the rocky slops by the "cabins" looking for the Infirmary Slabs with very little to reference where I was. The so-called "ranger cabins" are these obscure, abandoned buildings hidden in some brush behind a large fenced area that is on someone's private property just off the north side of the road before the pullout at 5.1 miles. These cabins are often referred to by guidebooks and others, but beware, there are no signs or anything to tell you those are the ranger cabins. So, set the gauge on your car. The mile post 28 pullout on the south side of the road is the best reference for the Infirmary area.
