Adding to other min on skier remote trigger above hanging lake. 2 large size 1s observed on unsupported slopes occurred between 12 and 1:30 both seemingly remote trigger. The first was a large ~1m thick crown triggered on a convex slope above a cliff with the debris running 100m down a 25-30° slope(not very deep). 2 photos below show this with on highlighting the crown and debris. The 2nd was around the same crown thickness with the debris running 15m and piling up again a tree on the flat bench below.
Triggered a few size 0.5s in the trees, again only on unsupported slopes. Very hard to trigger on anything less than 35°
