Weak snow formed in November is buried beneath 2 to 5 feet of snow at the base of our snowpack. The chance of triggering an avalanche that fails on this layer is slim, but not out of the question. We still see poor snowpack structure in snowpits, and this type of avalanche problem can lurk around for some time. Very steep, rocky, previously wind affected terrain is most suspect, as trigger points may be closer to the surface. Carefully assess slopes with these characteristics.

This was the last reported persistent slab avalanche that resulted in a partial burial.
