This avalanche was observed about an hour after it occurred. It was likely snowmobile triggered. A party that observed the avalanche did a beacon search just in case. This a a classic Logan area slide path that harbors weak snow and wind loads heavily due to its elevation and exposure. There have been two fatalities, one full burial accident and a few close calls in this same path over the past ten years.
