Slapjack

This is an interesting line that runs up the arete just to the right of penumbra. The sit start is hard enough to be interesting. After gaining the obvious jug hold on the arete you can either mantle and step up and right or continue up the arete. The step up and right continues to the top on lower angle but balancy VERY high moves. This is the only line I've topped out. The proud line follows the arete all the way to the top - which can be top roped (hard - 5.12?) but can't be exited due to massive vegetation.

bat cave boulder to the right of penumbra

pad at the bottom and then gravitron to avoid falling from the higher slab.
