12″+ loose snow wind slab with 2″ firm crust on top. Sitting on firm smooth layer that was observed to be exposed in the center of the chute.
Around 1pm, a skier triggered an avalanche on the steep skier’s right wall of Right Gully (HS-AS-R1-D1). This is a common spot for skiers to trigger avalanches in Right Gully because of the steep slope angle and the aspect of the slope changes from . . .
Wind slabs distributed widely through the terrain and mixed in with enough hard snow to complicate booting and skinning. Clean shears observed in the new 5″ thick wind slab formed over the past day or two led a party to bail in the approach to . . .
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 . . .
