Spent the day up near ski hill with West Yellowstone Avalanche Fundamentals course.
Our group observed a large collapse below ski hill.
We dug various pits @ 8000' below ski hill and found HS 85-55cm on NW-NE aspects.
The snowpack structure there had weak snow at the ground capped by a stout ice crust with faceted snow over the crust beneath the recent snow.
We recorded ECTP4, ECTP11, ECT20 & a few more propagating results on facets above the crust.
There was widespread intact surface hoar.
