From IG: Very touchy on Hollywood wall this morning. All slopes easily propagated 4-6” deep on a firm bed surface. Most were less than 50’ wide with the exception of the slide in the couloir which propagated down the entire couloir, maybe 500’ wide, and ran through the exits into the main bowl.
Today, we rode north of Cooke City through Abundance Basin around Scotch Bonnet ending at the East Henderson bench. We found anywhere from 4-12" of new snow that fell in the last 24-48 hours. Strong winds have transported this new snow into thick drifts even in more sheltered terrain. We did not see any recent notable avalanches but saw many crowns and debris piles from two weeks ago.
On the East Henderson bench, we dug a snowpit and found 235cm (almost 8') of snow. We found moist faceted snow 6' below the surface near the bottom of the snowpack. At the top of our snowpit was 12" of new snow above a stiff crust. Our stability test showed ECTN15 results on this interface.
Snow continued off and on through the day with little to no accumulation. Many slopes had signs of either wind-loading or had been scoured by recent wind resulting in thinner areas.
On our drive home we saw, what I assume were, natural wind-slab avalanches on Quarter Saddle (looked like a cornicecollapse) and in Argentina Bowl. Bridger Peak was obscured by heavy wind-loading. There was a small wind-slab release out of Gibbs (I think), I suspect skier triggered, but I could make out a track.
