Mission Impossible

Mission Impossible is a fun, thin corner on the extreme right of the Book. Hike up to the Book and continue rightwards past

J-Crack

and

Femp

. A long gully lies just right of Femp; to its right is a smooth slab with a clean crack (that doesn't reach the ground) on its left (

Endless Crack

), and a line of (currently) 1/4" bolts just right of that. Mission Impossible takes the corner system that borders the slab on the right. Start up into the LF corner, with a perfect 5.9 finger crack. The corner becomes very steep and thin; instead, take the flake to the left (crux, tricky gear) through blackwashed rock. Continue up a wider but easier crack to a rappel anchor. From here, a 60m rope will get you to some ledges just above the ground. Otherwise, continue up the moderate corner line until it is possible to walk off right and merge with the bottom part of the Book's 4th-class descent route.

Bring a double set of small stuff (include a few RPs), and a couple larger Friends for the top.
