Strange day. At and below 2050m the snow was extremely reactive but above that elevation and in wind affected areas the snow was non-reactive and skiable. Smart terrain choices were critical and we dug 3 different pits for observation.
Snow conditions were: Deep powder, Wind affected, Powder. Weather conditions were: Cold, Cloudy, Sunny. We rode: Mellow slopes, Open trees. We avoided: Alpine slopes, Steep slopes, Convex slopes. Riding quality was amazing.
Avalache Conditions: 30cm + of new snow, or significant drifitng, or rain in the last 48 hours. Slab avalanches today or yesterday. Whumpfing or drum-like sounds or shooting cracks.
CTE 1 SP 70 cm down on facets. The new snow is not binding well to the lower layers at tree line and below. On the way up in dense flat trees we witnessed around 30 different whumpfs. Once we reached treeline the whumpfs disappeared. Two highly different snowpacks between below treeline and above treeline.
We observed a 1.5 triggered before we arrived to the area that triggered on the convexity near a creek.
