Avalanche Summary
A couple of large cornice failures were observed last week in high alpine north-facing terrain. These loads notably did not propagate any weak layers on the slopes below.
Snowpack Summary
A dusting of new snow falls over widespread crusty surfaces on all but high north-facing alpine terrain, where snow is dry and likely wind affected. There are no deeper concerns at this time.
