This route ascends the arete that borders the light/shadow line in the primary image. There are a series of large huecos up high that could be used for gear/holds. The entire route overhangs some 50-100'.
Same as the other TH, but traversing along the south side underneath the rock.
Follow the scary arete to the top. Traverse east to the summit, descend NE gully route from bolted rap anchor.
Pitons? Varying gear? Not sure, although I have heard rumor that one of the climbing guide companies (San Juan Guides?) has guided people up this route.
