Snow conditions were: Wind affected. Weather conditions were: Cold, Windy. We rode: Alpine slopes, Mellow slopes, Sunny slopes, Open trees. We avoided: Steep slopes, Convex slopes. Riding quality was ok.
Avalache Conditions: Slab avalanches today or yesterday. Whumpfing or drum-like sounds or shooting cracks.
Local W aspect roll on overall S aspect. Strong NE’ly winds created hard slab along moraine roll. Significant area cracked and moved (100m x 10m) but transport was limited (<10m). Overall slope angles were fairly shallow (~10-15 degrees), likely why transport was limited and relatively (!) slow. Attention getting, and would have been significant on steeper, less supported terrain.
