Skied off north aspect of Point six's east ridge, ascended Burgundy. Steep east aspect convexities in the ridge top were notably touchy, whoomphing and collapsing as a result of the stiff slap overlying weak low density snow transported by the westerly flow. Strict adherence to ridge top security was necessary.
Valley bottom, direct Ascent of Murphy on 1/5 had revealed numerous mid elevation stiff wind slabs along the route from Point 6. In addition, a small R2 D1.5 avalanche was seen at the very top of the central southern couloir, which is now filled in. Although not reactive 4 days ago, assumption is with the large load from the last storm these slabs are now providing a hair trigger in isolated areas when traveling in the upper elevations of Grant Creek.
