A day late

Well seems like we were a bit late to the party. Traveled through a good portion of Allen creek today. We began our day with little trust in the snowpack. Lots of reports of natural and sled triggered avalanche activity over the last few days. I’m here to confirm those reports. We observed numerous natural slides on almost all North to East aspects with a slope angle greater than 30 degrees. They ranged in size from 1 all the way up to the full path release in avalanche alley (sz3) leaving over 3m of debris across the trail. Based on the reports as well as the amount of new snow sitting over the debris we suspect these events probably occurred at least two days ago. The failure plane was a preserved surface hoar layer down 30-70 cm deep depending on the amount of wind loading above it. We also spent a good chunk of time testing small slopes with our sled and we’re only able to get the one failure(see photo).
Snow conditions were: Deep powder, Wind affected. Weather conditions were: Stormy, Cloudy. We rode: Alpine slopes, Mellow slopes, Dense trees, Convex slopes, Open trees. We avoided: Steep slopes, Convex slopes. Riding quality was amazing.
Avalache Conditions: 30cm + of new snow, or significant drifitng, or rain in the last 48 hours.
