Natural avalanche (bison trigger?) in YNP near Cooke

From obs: 3/6/21: "Observed several smallish avalanches in Yellowstone National Park today. The interesting thing about this one is the bison track that goes into the slide. No telling if the avalanche was triggered by the bison, but the shallow snowpack is about 1/2 faceted, so maybe it was remotely triggered. Resulting in a grizzly springtime snack??"
