1. A natural wind slab avalanche broke beneath a cornice on Henderson Mountain, near Cooke City. It appears to have broken at the new-old interface, 2-3 ft deep and ~300 ft wide. Likely ran overnight on Monday 2/22/21 or early morning Tuesday 2/23/21.
2. Another smaller wind slab also broke further down the path.
4. Photo attached. I saw this SS-N-R1D2 on an E aspect at 9,000’ on the east side of republic mountain into Republic creek. I’m guessing it involved the HN plus some wind loading on old facets on a steep rocky face.
5. Southeast ridge of Mt Abundance broke under the wind-loads. It propagated a few hundred feet.
