On the Yellow Dihedral.


This is a fun and aesthetic line up the beautiful yellow dihedral. It is the most striking line on the Northwest Slabs and the climbing on the second pitch is stellar.

P1: Start up the dirty crack just right of two bolt protected single pitch routes (Turbo Pup and Flabby Little Girly Man). Move right and then up towards the base of the Yellow Dihedral and belay on the ledge.

P2: Head up the dihedral and enjoy! Move left in a hand crack onto the arete as the slab terminates near the end of the dihedral. Rail left and up towards a great belay ledge below the final bulge and belay.

P3: Head up and over the steep bulge and onto easier ground above. Walk left, skirt the pond, and regain the Greyrock trail to descend.


Hike towards the Northwest slabs and follow the cairns to the route's base below the obvious yellow dihedral. There are two single pitch bolted routes on the slab a few meters left of the start.


Standard Greyrock rack (pack light).

Perhaps I was off route, but I doubt it, but there are significant run-outs on the first and second pitches.

I climbed Yellow Dihedral with my girlfriend on April 4th, 2015 and she was unable to free two of our nuts at the first belay station just under the dihedral itself. One was a brass offset. If anyone is able to retrieve them, I would offer a six pack of your choosing. OH! and I thought that this was a worthy climb. I wonder if there is an easier descent than walk down the Greyrock trail, because that can take upwards of 30 minutes to get back to your stuff at the base of the climb. This climb is fun, though, DO IT!
