Lower down the snow was well bonded, but at around 5300feet we heard whumpfing and could feel the collapses in the trees where the trees opened on a small slope (48.70400° N, 121.03590° W). The photo attached was a pit where it sheared with no force. Very instable. We stayed left and went back into denser trees and kept digging pits. A bit higher up at 48.70140° N, 121.03580° W the localized slab we found was no longer visible and seemed well bonded. We continued to the top and observed no more whumpfing except on the ski down the same spot as we followed our skin track back down conservatively. The top near the peak had a wind slab of a few inches and was wind scoured but felt stable enough for us to reach the top.
