A grade 16 variant to the crux pitch of Cornerstone; climbs the corner by the tree inside the gully. I wrote this up in the book on the summit.
Also 2 climbs on Bluff Pyramid: both on the arete facing Bluff Mountain, Osiris Arete (March 1978) and a route next to it last Easter. I think I wrote OA up years ago in an SRC newsletter. By the way Bluff Pyramid is not really a major cliff with major potential.
There is a nice direct crack variant available to the crux pitch of Ginsberg. Will go at 21+ I reckon which is too hard for me, but it straightens the line considerably (by avoiding the traverse way out right & back left again that is the crux pitch of this climb).
