We got a good look at the Wellsvilles this morning in the morning light. Most drainages have some degree of slab activity from the weekend. Most of those slabs only involve the 12 inches of new snow. However, one exceptionis in Hell's canyon where it appears a cornice fall caused a slab avalanche involving the top foot of new snow and that stepped down to an old persistent weak layer several feet deep. Still some old dragons out there to be concerned about.
