Large to very large natural avalanche in the Swan Range, south of Swan Lake. Observed Saturday, 3/6, on ride in and out; likely ran 3/4 or 5. Crown near ridgeline. Possibly failed initially as dry slab, then entrained wet snow on its journey down hill.
Best guesses for size, aspect, and location based on image.
