Possibly triggered by Snowmobiler. There was one sled track near that climbed part way up the apron. Could have also been remote trigger from us powsurfing around the corner from where it happened. It was not there in the early afternoon when I arrived but noticed it about 1:30.

Forecaster's note: I think you guys remote triggered this from around the corner as I saw the sled tracks in the slope and the rider on the lake prior to the avalanche. The most northerly pocket was closer to 2' deep and it barely hit the lake....

Crown looked to be about 12-16" possibly. I didn't get up super close to measure. Didn't run all the way to the lake in most sections as I would have expected.
