Comments
Not sure where on the slope this slide was triggered from, possibly low on the slope and from a thin spot where the weak snow collapsed and propagated up slope. The second photo shows how you would not want to get caught in this terrain trap, where a small slide like this could bury a person quite deeply.
Comments
The slide looks to have failed on the early January facets, then stepped down into weaker snow near the ground. This side of the range typically has a shallow snow pack and much weaker snow than terrain further to the west of the trailhead.
