Snow Profile Comments
Moist new snow layer on top of heavier, stronger layer that was mostly hard and icy, but starting to melt a little bit.
It began with a width of only 4-5 feet. The Avalanche was loose and slow moving and ran for about 60 feet, entraining a gradually wider path as it descended.
It ended near a big tree, with a final width of about 20 feet. At its deepest, the debris pile was not more than 8-10”.
I triggered it while skiing down, but I was not caught in it. It seemed to start slowly, after I passed that spot. I was several turns further down, when I heard a sliding sound and looked back to see it. There was no whompfff sound, just a sliding sound, and it seemed to slide pretty slowly.
