Soft slab avalanche debris from this past storm cycle. 2/22-3/23. Debris pile wind effected and partially buried by new snow drifts. From Main Gully north, the gully tops were scoured or very heavily wind effected. Below this we found smooth slabs . . .
Natural large hard slab avalanche that likely occurred late Saturday. HS-N-R4-D3-S. A true “Bowlalanche”, this crown is connected from Lower Sluice through Center Bowl and all the way to Chute. We think a soft or wind storm slab avalanched on Friday . . .
We ascended from Hermit Lake toward the Bowl via the Little Headwall. Using the looker’s right fork of the Little Headwall as our route, we remotely triggered a soft slab that released about 30 ft from us. SS-ASr-R1-D1-S. Upon arrival at Hermit Lake . . .
Warm day with occasional high thin clouds and a light wind. 34F on the summit when this picture was taken. Felt much warmer in the ravine. Top 8 to 10 cm of snowpack moist/wet, roller ball activity increased through the afternoon on south, south east . . .
Huntington was in full sun all day today.
Roller balls began being observed after 12pm – the two skiers were in ski track below Yale when the slide started (originating in Yale) gave them a pretty good scare- we heard it before we saw it.
Slab was firm pencil to knife hardness first run at 930am . Snow intensified to 1”/hr. Roughly 2” accumulation + wind deposit. Sluffing off of the ice below crux resulted in 20-30cm pockets. Second hiker on third run triggered a small R2, D1 slide . . .
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 . . .
