Jack Knife is the prominent cleft in the large boulder at the top of the purple climber’s trail, just left of Orient Express. It is undoubtedly one of the best 5.5s in the park and provides the most direct access to Cave Crack on the wall above. Climb a short face to a low angle, right-angling hand/fist crack. The crack is a lot of fun, protects well, and has positive hand and fist jams all the way to the top. The crux is a slightly steeper section about two-thirds of the way to the top. Two rappel bolts are located at the top of the rock on a small summit block.


Light rack with a couple of medium sized cams.

Easiest and fastest appraoch to "Cave Crack" Also protects easily. There is a 5.9 sport slab route that shares the base of this climb for a little variety in the same general area.
