This excellent route starts about 3 meters right of "Chiba Chiba" on Menses Prow. This route has been confused as being "Chiba Chiba" but is a separate route all together.
After getting thru the initial chossy start, the route trends up and right to a small roof. Get ready for some powerful moves to clear the roof. The climb ends shortly after this crux section. Rick Thompson gave it a rating of 12a/b and I feel it's closer to 12b.
