Start compressing the arete with your left on a good crimp and your right in a slopey dish/pinch. Lunge for a right crimp, then bring your left across to a good sloper. Reset your feet, and find a way to get your left out wide. Crunch your feet up so you can stand up to higher crimps and top out.

The fun of this problem is the footwork; the feet are either tenuous or not there till you can get high enough to stand on the face.

This problem is on the south-facing prow of the Stock Exchange Boulder.

A pad and maybe a spotter. The problem is low to the ground, and the landing is flat, so pretty much no chance of injury if you pop off.
