This problem ascends the overhanging face right of the southeast arete of the Amphitheatre boulder, using the arete. Start left hand on arete, right hand on a low sidepull crimp. Using your choice of sequence, bump your left hand up the arete to a good hold about 8 feet up, walk your feet up on small edges, and pop your right hand to the triangle shaped incut sidepull above. Once you establish on these two handholds, the crux is over. Continue up and eventually go left around the arete onto the slabby south face and top out.
