Subject: 12/4 Natural Avalanches
Aspect: East
Elevation: ATL/NTL

Avalanches:

Several recent natural avalanches were noticed on Whetstone Mountain (North Ridge of the M Face), Mt. Richmond (ran during the day 12/4), Purple Ridge, East ice of Mt. Owen (photo attached) and Mineral Point.

Weather: Sunny and cold with temperatures in the single digits. Winds were light at lower elevations but obvious flagging was noted off most peaks above 12,000′
Snowpack: On S-SW slopes below treeline the persistent slab structure was intermittent and seemingly unreactive. A crust above the Thanksgiving snow was found in some areas, but not all.
