Whiteout

Blackout

Sit start with your left hand on a decent crimp and your right hand on a higher, slopey hold. Make a crux first move, and then cruise the topout.

Sit start matched on the decent crimp, and traverse left into the problem Whiteout.

Stand start the steep arête/face, head straight up, and top out.

Abyss Boulders are a group of about 5-6 good-sized blocks.
