Obsidian Corner

Climb the corner and the arete to its left with increasing difficulty (crux) to its top where big flakes and holds appear. Chimney or bridge the slick flared corner up to the 4-foot ceiling and climb directly over the roof (second crux) then easier to the top.

This is the second black dihedral right of "Vulture Roof". Though it is only a few feet right of "Moment of Inertia" it is an entirely independent line all the way to the top. It shares the glassy slickness of "MoI" and is a step up in difficulty.

No bolts at top. Excellent top-rope anchors can be set along the grand traverse ledge and used to TR both this route and Moment of Inertia.
