Back up Avalanche Crest for a lap. A lot of new snow, with no wind effect 30 to 50cm on top of the Nov 17 crust and 100+ on the Nov 5th crust. Evidence of large avalanche during storm cycle on the SW facing moraines on the way up, very large propagation, suspect on Nov 5th crust. (See photos.) We had a couple of un-supported pillows pop off on both the Nov 17th and Nov 5 (see Photo). Had a large settlement on a big planer slope dropping into Avalanche Crest proper, on the Nov 17th crust, with shooting cracks. Skiing was great but felt a bit spooky out there.
Snow conditions were: Deep powder. Weather conditions were: Stormy, Foggy, Cloudy. We rode: Open trees. We avoided: Alpine slopes, Convex slopes. Riding quality was amazing.
Avalache Conditions: 30cm + of new snow, or significant drifitng, or rain in the last 48 hours. Whumpfing or drum-like sounds or shooting cracks.
Large propagation on moraine feature above the skin track up to avalanche crest. Supect on Nov 5th Crust, during the warm up on Nov 17.
