Route & General Observations

Up the general uptrack from the gate behind the lake. Had reached the first flat spot of the ridge. South side was absolutely wind hammered and headed around to the north side to see if the trees were worth skiing.

Observer Comments

Started to skin across the north side. Not positive of the exact altitude but there were still trees around me. I was going to check it out to see if it was worth coming over to or if we should just ski the ridge down.
I got to a point about 200 yards from the where I crossed the ridge, heading southeast, and realized it was a waste of time. I was about to turn around and there was a giant whumph under my feet and I looked behind me and the slope was sliding above and behind me, but didn't slide where i was. One in the group slid for about 30 feet but not buried. Not exactly sure how wide the slide was but I would say about 100 yards or larger and it ran down into the trees so you couldn't tell how far it went. I estimated the slope to be between 30-32 degrees from past experience and others input. The crown varied due to snow drifts around trees but id say an average of 18 inches to 2 feet. It was a hard wind slab. It didn't give any red flags, no shooting cracks and no whumphing until the actual event. I didn't do any more investigating or take good pictures because we were working on getting off the slope.
