Quick report

Fresh snow, beautiful weather, and the holiday break have done a great job of getting folks out on the hill at Hatcher Pass. At least half a dozen people were observed climbing every established skin track at the pass. Skiers and riders are out enjoying the road run and the Archangel lot is full of Nordic skiers. With an impressive number of tracks on Marmot, Eldorado, and Hatch, the most notable observation was the lack of skier-triggered or natural avalanche activity. We were most grateful to observe a lack of widespread wind effect from yesterday's forecasted strong winds. It appeared that the conditions never really materialized for these winds to mix in with the valley's stable weather and produce strong winds on the ground. We observed some interesting scouring and natural activity related to yesterday's wind on Frostbite and in the Government Peak Basin, but this was isolated in distribution and small in size.  

We were able to trigger one small loose sluff on a steep NW facing slope at about 4000 ft. A number of older skier-triggered sluffs and a limited amount of natural wind-triggered avalanches were also observed (see pictures).

Beautiful day. Cold and clear with light winds that often felt calm on the ridge near 4068. The most noticeable feature of the weather was the surprising lack of wind effect from yesterday's forecasted strong winds.

Snowpack

A few cold clear days have again driven faceting within the snowpack and a nice layer of loud-pow was observed on shady and sheltered slopes. Overall the snowpack structure remains unchanged with mostly faceted grains and variability with several distributed crusts to be found throughout the area. We dug on a NW aspect at 3700' and found the following: HS 60cm, no recent wind loading or new wind slab formation in this location, new faceting snow from 11/25-26 on the surface sitting on top of a firm wind slab, sitting on numerous large facets from Oct, on top of a couple facet/crust layers. We found no instabilities or failures in our pit today.  We did not observe any red flags on our tour.

Avalanche

Most notable was the impressive lack of avalanche activity, given the large number of recent ski tracks in the area. A few small loose-dry sluffs were observed from skiers that occurred in the previous several days. Some interesting scouring and natural activity was observed in gullies on exposed, wind affected east aspects of Frostbite and in Government Peak Basin (see pictures). All recent avalanches over the past week have been small, infrequent, and few compared to the number of tracks being laid down.
