A skier in Cooke City noticed multiple avalanches around Mt. Horinday, Barronette Peak and Mt. Republic. Most avalanches appear to have failed within the new snow or at the interface between new and old snow. However, one of the slides on a steep, rocky convexity on Mt. Republic failed 3-4' deep on a persistent weak layer.
