Avalanche that appeared to involve 3 snowmobiles, but no one appeared to be hurt. One machine had to be towed back to the guard road parking. Occurred on the up track near the ridge by one rider. Possibly avalanching his buddy. Took an hour to get machines running and out of the situation but being obscured by trees made it difficult to see. Hopefully a better incident report from those involved but possibly not because of being on private property.
