Small slide in terrain trap. Looks to be old, likely from before the wind event that occurred mid last week. A snowmobile track leads into it with wind-drifted snow covering the track. Photo: L Welles

Above 9000’ winds were actively loading the snow and I got cracking and a very small slab to release on a small wind drifted roll over at 9500’ on a N aspect. Photo: E Heiman

Avalanche in Hourglass chute above Wolverine. It looked to be triggered by an intentional cornice drop, was around 12 inches deep at the crown, 100' wide and ran 850' vertical feet. It looked around three days old.

Toured up into the Blackmore area today and found a pretty interesting upper snowpack with everything below roughly 8500’ wet from yesterday’s green housing and up slope winds in the Hyalite area. From trailhead to our peak elevation at 9500’ the new snow from last night ranged from a dusting to about 3 inches and capped the wet snow. Above 9000’ winds were actively loading the snow and I got cracking and a very small slab to release on a small wind drifted roll over at 9500’ on a N aspect. Later in our tour we dropped a cornice on an E slope and there was no avalanche activity, albeit the snowpack below the cornice seemed to be very thin as the cornice pulled off most of the surface snow and exposed a lot of rock. Overall decent ski conditions above 8500’. 

We experienced several collapses and had propagation in multiple ECTs performed.  HS varies between 85-105cm. Photo from 9940
