Notes

Big Sky Ski Patrol reported two natural avalanches seen today (12/15) in closed terrain. 

From email on 12/16: "Further investigation of the avalanche yesterday showed goat tracks leading into the crown area of the avalanche. At the debris pile, it was obvious that a goat had taken the full ride in the slide that it triggered. There was a depression in the debris pile where the critter had come to rest at the surface, and obvious hoof prints trailing away from the debris pile, and then upslope for the long walk back up to rejoin the heard. There was no blood, and the tracks looked usual, with no obvious sign of broken leg(s). It is unknown if the goat was wearing an airbag or if it was deployed in the avalanche. It was a significant ride, 1K’ vt., 1⁄4 mile linear, likely of high speed, through 2nd Dictator transition, which was taken down to mostly bare ground."
