Powderhouse Peak is the subpeak to the west of the main Waterhouse. Many skiers chose to ascend and ski Powderhouse. In that case, park a half mile to the west of the forest service sign, and follow tracks up. Be sure to return to the meadow, and if visibility is poor, check your compass. Going too far to the west is easy and forces you to ski annoying flat terrain with a stream crossing, then you have to hike back uphill to the car.
