General Comments

75% of north facing West Bowl naturalled overnight Dec 30/31, perhaps later in the storm; other pieces likely earlier as they had some dirt/snow blown in onto the crowns. Seemed as if the western most terrain pulled out to the ground. Others 8-12" above the ground into the faceted snow.
