Very variable conditions. Highly aspect dependent; hiding from the wind produced superior riding conditions. ALP & ATL were near whiteout. BTLprovided some refuge and delivered the best conditions for riding, but not toolow where we experienced firm damp snow overlaid with recent storm snow. Recent storm coverage was not complete enough to provide consistent lines. Wind transported pockets were too touchy to ride confidently.

Snow conditions were: Wet, Wind affected, Powder. Weather conditions were: Stormy, Windy, Warm. We rode: Alpine slopes, Mellow slopes, Dense trees, Convex slopes, Steep slopes, Open trees. Riding quality was ok.

Avalache Conditions: 30cm + of new snow, or significant drifitng, or rain in the last 48 hours. Slab avalanches today or yesterday.


Sustained extreme wind. Intense blowing snow. Navigation >1900m was full on white out punctuated by brief periods of fair visibility. Travel BTL was manageable due to wind shelter.


SZ1 (barely) LS Sc ~1700-2100m on wind loaded pockets. Cakey 5-20cm isolated pockets over dens-er moist-er base were easy to peel off.
