This Route is on the W/SW face of the Sibling, essentially on what would be considered it's back side. The best approach to this is either up to the North side and then up around to the West, or going West until parallel with the top of the rock and slightly above, then dropping down into the West face from the South.
This climb starts from near the Northwest Arete. Step right (South) onto the center of the West face and diagonal up and right a few feet to a crack and corner system. Follow a right-facing corner up to a roof formed by a huge chockstone. Protect on good gear, and stem up and through the roof to more good crack- climb that to reach the tree at the top of the ridge, and the fixed anchor in place there.To descend, rap from the the fixed anchor.

[Hide Comment] Fun, short, little route with great views of The Matron and an unpleasant approach. Do not approach from the gully to the south unless you really enjoy kick-stepping into loose duff and rock. The tree was clean of any anchor on 10/14/2022, so we left some cord and a couple biners. Based on lack of traffic to this area, one should come prepared to replace what we left behind.

[Hide Comment] Today we failed to heed Holly's warning and kicked steps from the south, only to audibly laugh when I realized how short this pitch is. We added another pass of cord to the tree anchor on top.
