Such a great crack....if only it was a full rope l...


This is the corner above the right side of Wiessner slab. Either climb the slab, set your belay, and contemplate leading this climb in 1934 with ancient gear or start the corner from the ground on the inside of the chimney. By starting in the chimney(5.6+) it is easy to do in one pitch.

This is a stiff but protectable lead that takes a variety of gear. You can protect just about anywhere if you can hang in there. I've seen some serious falls on this when the leader decided to just go for it.

Hassler Whitney is famous for the Whitney-Gilman ridge on Cannon, put up earlier in 1929.


Standard traprock rack. Wires, some cams.

Yes, climb the hole. It's rather spelunk-ish.

In Summer/Fall start in the cave/chimney! The change from enclosure to exposure adds to the fun.

In the Spring, there's usually an occupied bird's nest right on the back side of the slab near the opening. Climb the slab then.
