This awesome arete problem is tucked away in the heart of Boulder Natural. Start sitting and layback up the underside of the attractive overhanging corner, then flip your body to the slabby side of the arete and make a super fun and delicate smearing move to top out at the apex. If only it were longer! Pictures of this aesthetic problem have been featured far and wide.

The top out mantle crux is  very committing and can spit you off in a lot of different directions, make sure you have good pad coverage and multiple spotters at multiple angles

3+ Pads and multiple spotters at multiple angles, you can get spit off the mantle in several different directions
