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."
