We started at the unnamed creek north of Slaughterhouse Creek (took CR LL56/FS 861 from Villa Grove; 2WD is fine) and ascended northwest until we were on a shallow rib. We did not descend back down the western side of this rib but continued up towards 12er Sheep Mountain then curved around under it. There was a snowfield crossing or two but nothing major and the snow was mostly supprtive; no postholing. We then ascended directly up Antora from the Antora/Sheep saddle which was steep and on dinner plated trash. Kind of irritating but could definitely be worse. Instead of descending the way we came we went over Sheep Mountain and Sheep Mountain's northeast summit, avoiding all snow. We descended back to the Sheep/Sheep Northeast saddle then down towards Mosquito Lake on steep, hummocky dirt, then found an old disused road that we followed back to our cars.
