Left Infirmary Slab Rock Climbing
BETA PHOTO: From the Road. Hamburger goes through the middle o...
Left Infirmary Slab has two 5.8 trad/slab routes that are really only notable if you've already made the hike to Upper Infirmary Slab and want to get some more routes in. They're longer routes, but the cruxes are at the start and the rest of the climbing is really easy. Scramble down the right side of the formation to descend.
As for Upper and Lower Infirmary Slabs, drive 5.1 miles up the canyon, and park at the pullout on the left (best to drive a little further and turn around at the turn off to the Forest Service Ranger cabins). Either hike up the trail to Upper Infirmary Slab and rockhop/bushwack 100 yards west (climber's left) and slightly down to the base of the slab OR hike up the road part way back to the cabins and the lower angle rockfall area and hike up the hillside trending up and right straight to the base.

This is the bolted fin of rock approximately 75 feet East of the route "Wax 'n Wane". Start at the base and begin by passing 4 bolts to a large, horizontal crack. From here, the angle eases off, and it is a fun and easy climb past 3 more bolts to the anchor. Overall, it is a fun slab climb with a definitive crux at the second bolt. It has 7 bolts to a 2 bolt anchor with chains. ...[more] Browse More Classics in CO

If you are there, it also contains a short, fun 5.10 crack to a small tree. It is between the other routes.
