Comments: 
Saw this on my way out today. It happened within the past 2 days, based on the current wind transport in the area. There were several larger slides on bald mountain and dry mountain that happened early in the week. They are mostly filled back in with new windblown snow. This slide is lower elevation but the wind is still blowing and it's not filled. The trigger is unknown and the slope angle doesn't appear to be more than 26 degrees. There is a new crust that formed last weekend, Darce sent in an OB with that. We had 2" new light density snow on Wednesday with a short burst of graupel. Winds continued to blow today and it stayed cold. The snowmobilers are getting on some steeper slopes for the first time this season. Wind slabs on top of the new crust could become a problem.
