Steamboat

Just left of the pillow-sloper arete look low for the long edge rail that runs just above the low undercut roof at the boulders base/corner.

Star matched on the rail. Reach up to an edge and then up to the juggy ledge. Continue up the face until standing and reach out to the nearest arete sloper. Continue up the face to the top arete sloper and top out. Continue up slab with iron edges and chicken heads.
