Anthracites

Date of Observation: 12/12/2021
Name: Zach Kinler

Zone: Northwest Mountains
Route Description: Anthracites, standard up-track to the ridge

Observed avalanche activity: Yes
Avalanches: The slide lookers left in 7 bowls is quite impressive, propagating very widely on a slope that typically gets more scouring than loading. Debris was deep across the typical egress from 7 and blasted into the trees hitting the standard uptrack as well. Very active in the Playground area with most activity on these N and NE aspects breaking early in the cycle. Bed surfaces have largely filled back in and debris buffed smooth.
Weather: Perfect winter day, cold temps but abundant sunshine and little wind near and below treeline.
Snowpack: HS in Anthracites around 150 cm, we got a couple of collapses but overall somewhat quiet breaking trail on shady aspects below treeline. Many slopes 35 or greater have avalanched or shattered. On a SE aspect at 11,200, there was no old snow found with around 70 cm of settled storm snow on dirt. The surface was slightly moist while S aspects had a moist upper couple inches of snow. Small surface hoar and near-surface facets were noted in the shade.
