Natural Avalanches near Miller Mountain

Activity
Snowmobiling

Around 4 or 5 pm today we rode out of Sheep Creek into the Miller Mountain area. When we looked at Miller there was a large avalanche that appeared to have occurred naturally (to our knowledge). It looked like the crown was 12-24'' and a few hundred feet wide. The debris looked fresh and must have occurred today. Given the depth we assumed it was windslab that had built up sometime in the last few days; however, hard to tell from so far away. We also observed another smaller natural avalanche on an exposed ridge below Miller Mtn, this looks to have been about 12in deep and probably occurred on the same layer as the larger avalanche. Both were on N or NNW facing slopes in areas with heavy wind deposition.
