I found new debris in the bottom of Gully #1 and Gully #2. There was none in the south snowfield and I did not travel in any area north of #2. Debris in both gullies was wind affected but with some chunky wind slab evident. Debris pile in #1 was . . .
4″ of new snow overnight, several hours of W-WNW wind @ 50-70 mph. Moderate results withstability tests in the new wind slab, but overall a mix including pockets of new wind slab and old bed surface. Frozen boot prints from before this recent snow . . .
Moderate wind last night had a strong effect on the 4″ of new snow that fell Sunday night into Monday. We encountered a stout skin of firm wind slab over soft snow in the Little Headwall that was reactive under ski, complete with shooting cracks and . . .
Some new slab development and small avalanche activity as of this morning, before the wind increase. Numerous D1 natural slab and loose dry slug releases, with the largest from the Northern gullies. We were able to initiate a small slab (~3” thick) . . .
Snow started off firm on bootpack up and softened as I made progress higher. On descent, was quite soft. Saw a few others bootpacking up and was questioning my next move and side slipped to skiers left when I saw a crack propagate. Yelled avalanche . . .
2 human triggered avalanches in the Headwall of Tuckerman Ravine this morning, both soft new wind slab. Chute: SS-ASu-R3-D1.5-I, Lip: SS-AFu-R3-D1.5-I. Both crown heights up to ~16”, mostly thinner. No one caught or carried.
~1″ of new snow overnight on WNW wind drifted to 3″ of soft snow in the GOS. Snow was light with almost enough density to keep skis from feeling the firm (P) bed surface below in most places, almost. Crampons necessary for the climb. Shiny bed . . .
New snow was reactive. Skier slough from first few turns triggered small wind slab that ran past ice bulge. 4-8″ crown, about 20ft wide. Perhaps R2 D1
Our trip to Ammo was rather interesting today, with a fair amount of surprises. As we skinned up, snow conditions in the bushes areas below varried from step to step. We left the main drainage and began skinning up the south basin of Ammo, which . . .
