Comments
The natural avalanche off the Long Mountain Ridge west of Millville Peak was most likely triggered by a cornice fall... An interesting mid-slope step-down occurred when debris from the avalanche overran the open slope below the trees. The 3+' deep step-down occurred on a 33 degree north-northwest facing slope at around 8400'.
Comments
At least at the step-down crown, the slide failed on 4F sugary or faceted snow a few inches above the still prominent MLK ice-crust.
