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??"
