Weather
Moderate W/NW winds with strong gusts. Periods of moderate snow transport. Mostly cloudy with intermittent flurries (S-1) through the day. Cold temps.
Snowpack
2″ of storm snow evenly distributed across the terrain, over the Dec 13th near surface facet layer. Not enough for slab formation, except for below ridgelines and a few wind affected features, where winds had drifted the new snow into 3-6″ of a more cohesive slab. Anywhere that a slab had formed, it was very touchy underfoot.
Avalanche
Several human triggered and one natural loose avalanche that gouged into old snow and ran as much as 1,200 vertical feet. Debris piles 3-5′ deep. (L-AS/N-R1-D1/1.5-O). Also skier triggered several soft slabs below ridgelines that failed on the Dec 13th NSF, and ran far, gouging into older snow. Most of these were 30-40 feet wide, but one was almost 200 feet wide, and ran about 1,000 vertical. (SS-ASc-R1-D1/1.5-I)
