Black Cat Bone

Start with a difficult crack bolder problem to the right of the obvious flake start to Twelve Gauge IQ. Climb part of that route and step over to a finger crack on the right face. Getting started in the crack is the crux. One can traverse left at the top into the sport climb Twelve Gauge IQ, or, I believe, head right to another anchor. I can't remember if this other anchor currently exists, however.

A 60m rope lowers from either anchor. This and the aforementioned Twelve Gauge IQ are located on the far left side of the Blues Cliff, to the right of Accidental Discharge.

Finger-size cams and stoppers with maybe a couple of hand-size pieces. This climb used to have bolts next to the crack, but as per Chris's comment below they've been removed. Fixed anchors.
