I was told this happened on Thursday 1/10/19, there was 1 snowmobile track entering the Avalanche. Submitting because I didn’t find a report for this slide. I am guessing on the pin drop, but the slope was SE aspect around 9,400’ around Duschesne Ridge. Lots of tracks around this slide, but this is the only one I saw today. The slide broke 20-30’ above the sled while they were sidehilling on the slope. I would guess this problem still exists throughout the range where wind loading occurred.
