Noted this crown in Hell's Canyon today. Unsure when it released, but no tracks into it, so presumably natural trigger. While it doesn't really show in the photo, it was quite a crisp looking crown from a distance, so I imagine it failed late in the storm cycle--otherwise it would have been more filled in. Best guess is 16 or 17 February.
Ran almost the full track with debris at least 1000ft below. Crown appeared a couple feet tall and a couple hundred across, certainly D2. Clearly in the start zone; lidar slope shading has it pegged between 35 and 45 degree slope angle. Did not scour to ground, so storm interface seems likely.
