Snow conditions were: Deep powder, Wind affected, Powder. Weather conditions were: Windy, Cloudy. We rode: Mellow slopes, Open trees. We avoided: Alpine slopes, Steep slopes. Riding quality was good.
Avalache Conditions: 30cm + of new snow, or significant drifitng, or rain in the last 48 hours.
Compression test at 2450m west facing. 30cm storm snow was forming a soft slab and gave a sudden collapse at CT11. Another collapse at 40 at CT13. Collapse with two tests at 15 on November crust and at 17 (7th elbow tap) failed to ground. We were expecting a cleaner and easier sheer in the November crust...it seems to be starting decomposing at this elevation bit certainly still there with facets above. Great turns but moderate to strong winds from 2100-2550m.
