Notes
From email 11/15/21: "east Henderson had a fresh slab avalanche- on a NE aspect around 10,000'. It appeared to have failed on a weak layer near the ground, and I'd guess it was about 2-3' deep and 300'+ wide. (photo attached)
Also noted some other natural slab avalanches on some northerly aspects of Miller Ridge. (steep rocky starting zones). And noted a couple big slab avalanches on NE erly aspects up Republic Creek too. Similar thing there: steep, rocky, wind loaded starting zones."
