I skied the B-P Cleaver to Boulder HW in April. We didn't climb the Park HW because we didn't want to ski it. The approach is casual, an hour's hike through flat forest, then you go up until you hit the ridge coming down off the cleaver. The cleaver is spectacular, very pretty side of the mountain. At the top of the cleaver, the HW is dead ahead, either climb that, or contour climber's left towards the crater, then up the final bit of the Boulder to the summit.
Take skis, the cleaver is fantastic. Watch out for cracks at the top of the cleaver, they were opening up when we were there.
Here is my TR.
