An observation outside the party involved and photograph supports the theory that this avalanche failed in the basal facets.
Models indicate that temperatures will be rising this week, possibly reaching 35-37 deg F at 3000'. These temperatures will allow the new storm snow to settle and become more cohesive. Expect the new snow to become more reactive to human triggers, on slopes 35 deg and steeper, and for avalanches to increase their propagation potential and size. Also note that in isolated areas new snow avalanches may be able to step down into deep, hard slabs, over very weak, basal facets near the ground, compounding the consequences of an avalanche.
