Compared to Saturday the winds have really hammered the area on all aspects and in open areas below treeline. We found one west aspect that had ok wind-sifted snow on it. The wind storm resulted in a size 2 to ground and 1.5 slab avalanche from beneath Mt. Tyrwitt that could have been triggered by cornice falls(marked in red). Are snow pit at 2350m on a west aspect had HS 73cm, the October crust was present but not very reactive, and the new 10cm hard wind slab was bonding poorly.
Snow conditions were: Crusty, Hard, Wind affected. Weather conditions were: Windy, Warm, Sunny. We rode: Alpine slopes, Sunny slopes. We avoided: Convex slopes. Riding quality was ok.
Avalache Conditions: Slab avalanches today or yesterday.
