Avalanche Details
On the way back to the Goldmint lot from the base or Arkose Peak, we toured up for a bonus lap near point 4226 on a W aspect. As the third skier on the slope, I triggered a small bit deep D1 soft slab avalanche that failed in a area where the snow pack was thin and over lieing a steep smooth rock slab. I was able to ski off the slab without being caught. The other two skies were in a safe zone and got blasted by a powder cloud. The avalanche ran an impressive distance, but the slab was small and isolated to the thin section over lieing the steep rock. Crown depth 2 feet. We did not perform a crown evaluation but I assume the rock slab allowed for basal facets to form in a thin section of snowpack.
