Beau, where in the park was this photo taken?
Pebble Creek. East, southeast facing, around 8,800'.
Beau, wow that Crowned on top of that wind slab!Looks like the wind slabs and the drifts in Eastern Montana right now, but smaller... yeah I said smaller. Imagine cows and antelope buried in that with just their snouts sticking out of the snow. BC
Two things concern me about that photo, the dead whitebark (I've got to investigate this ridge), and the fact that the Av. was remotely triggered. I figured various slabs/cross-loads could break underfoot, but what layer in the snowpack allowed energy transport for this sympathetic release? YOF
Small grained facets over a m/f crust. (primarily)
The double terrace of the crown on lookers left is fascinating. Ostensibly a fat wind slab that collapsed and then stepped down to the m/f crust you mentioned and then propagated out upon that layer?
