Ted and I visited the site today and found a relatively shallow snowpack for early March. Witness reported it was the 4th time up the slope. Sledder triggered slide mid-slope where the terrain gets slightly steeper. Snowmobiler was able to outrun the avalanche.

Looking up at the crown which was 3'-4' deep and approx 75 wide, running 250' vertically.
Overview from the bottom up. Curious that adjacent slopes with similar terrain characteristics didn't avalanche.
