Impossible Crack

The crux is definitely the transfer into and out of the offwidth crack. Some may find it useful to use a headjam and it is definitely a route you'll need some energy for.

Head to the Wisconsin strip and use the usual scramble decent, head past inside corner about 20 ft. If you look up to your left you'll see an offwidth crack slightly overhanging and this is the route.

A few medium cams for the bottom. A #5 and an optional #6 C4 for the offwidth section.
