Blowing at Bullmoose

North Rockies

It was sure blowing today at Bullmoose! Strong southwest winds were loading massive amount of loose snow onto lee features.We avoided freshly loaded slopes, and stuck to sheltered areas around treeline where we found some pretty good skiing. We saw signs of several smaller avalanches that had come out of steep cross loaded terrain and one larger avalanche that ripped out most of an alpine bowl. All this wind slab activity is forming over a persistent weak layer down 110cm in the Bullmoose zone. Thats a pretty deep, firm slab! This layer is made up of surface hoar buried at the start of February and is still showing concerning test results in our snow profiles. This problem is most concerning where the reactive wind slabs may step down creating very large avalanches. Both of these problems may become amplified as the next warmup hits later this week.

Snow conditions were: Hard, Powder, Wind affected. Weather conditions were: Windy. We rode: Open trees. We avoided: Alpine slopes, Steep slopes. Riding quality was ok.

Avalache Conditions: Slab avalanches today or yesterday. 30cm + of new snow, or significant drifitng, or rain in the last 48 hours. Whumpfing or drum-like sounds or shooting cracks.
