The SW Butt of Flathead has several variations too. On our first attempt on MHE, we got baked and had to retreat. We had saved one gallon of water at the base of a tree about 100 feet down from the route. At about 5 pitches up Bruce dislodged a fist sized rock that bounced left, right, left, right, right, right Blewy. The water was gone. I almost got in on the 1st ascent of Marvin's wall too. But there were already three and it sounded like a waiting game.
