Climb the arete to the R side of the obvious black water runnel. You can either stay on the arete (straight up the bolt line) or stem up the corner by climbing L of the bolts (much easier) or some combination of both. The crux is pulling the roof at the top; it's a little awkward with the holds being less positive than you would like. Mantle out and trot up the remaining slab to the chains. One of the longest routes on the wall. Rock on the arete is still a little loose. My belayer drilled me with a nice cobble so watch yourself.
