52″ Depth
Primary Problem: Persistent Weak Layer
Bottom Line: Avalanches that break 2-4 deep on weak snow near the bottom of the snowpack are possible for a person to trigger. Additionally, wind slab avalanches up to 1-2 feet deep can be triggered where recent snow was drifted into stiffer or thicker slabs. Choose slopes that are non-wind-loaded and with a relatively deep and more uniform snow depth, or stay on slopes less than 30 degrees to keep it simple.

While driving to and from West Yellowstone today, I noticed what is potentially a skier/snowboarder-triggered avalanche on the east side of HWY 191 on a West/Southwesterly aspect, directly across the highway from the Bacon Rind Area and Snowslide Creek.  There were numerous tracks through steep rocky chutes next to the road, one of which had avalanched perhaps 75' wide, 18-24" deep, and running nearly to the flats at the base of the slope.  Judging by the thin layer of fresh snow it potentially happened on Sunday or maybe Monday.  There were tracks through the cliffs above the slide and coming out of the slide.  

***Attached video is from a GNFAC field work at Bacon Rind unrelated to the avalanche, but likely on the same day***
