Like Sonic Youth in Clear Creek Canyon, the Sonic Crack is a pretty unique feature. It is different in the sense that it is an overhung dihedral/crack on an arete. SDS on two good holds and move up using the crack only. Bust out of the dihedral to a large bucket and bulbous feature. Hand/foot match on the bulb and slap up top for the slopey top-out. I would say best warm-up or beginner problem in the park, and would easily be worth 4 stars if it wasn't for the boulder right behind the problem. GET ON THIS!
