A sit start 1 m right of The Mission. Sit start on the foot rail directly below a diagonal undercut just left of the arete. Move into this undercut to gain holds left of the arete, where high feet and a long reach gains the crescent crimp. The arete is out.
Originally claimed as a sit start to The Mission but confusion over the correct starting point for The Mission shows this to be an independent problem just left of the arete.
