Snowpack Observations
Details
In the Garfield Peak area between 6400-8000ft, the height of the snowpack ranged from 80-130cm. The height of new snow by the end of the day measured 40-50cm. Natural dry loose sluffs were observed in steep north facing terrain dropping down to Crater Lake. Evidence of wind loading was easy to find near ridgelines. Stability tests found a density break within the new snow that produced resistant planar fractures and no propagation. Plenty of rocks and sticks were exposed and the overall snow coverage felt thin. The skiing was good on open low angle slopes with smooth ground cover.

Snowpack Observations
Details
Coverage above the gate on the Everett Memorial Highway is getting thin. A few patches of bare road were exposed today. Two trees have also fallen down, but are easily passible. A good trail made for an easy ride to the base of the west face of Grey Butte, where the height of snow ranged from 40-60cm. Above 9k in the Old Ski Bowl, snow height ranged from 80-100cm. Our snowpack is an isothermal mass that has refrozen solid. It is comprised almost entirely of melt forms - clustered rounded grains and melt freeze crusts. These dominate the snow surface form as well. Wind eroded snow can also be found at the snow surface. Very firm and supportable snow surfaces were widespread throughout the terrain. Snowpack stability was very good today. Southerly slopes below 10K softened with direct sunlight. The corn riding was pretty good by December drought standards.

12-17-17 General Conditions & Climbing Information
Submitted by akiefer on Sun, 12/17/2017 - 10:18am
General Message:
Hello, and thank you for visiting. You have arrived at the best place on the internet for avalanche, climbing and weather information for Mt. Shasta.
General Conditions
Winter conditions exist on Mount Shasta, and the Climbing Ranger program has switched focus to the Avalanche Center. Avalanche advisories have begun and these daily reports will be the best resource for current conditions on the mountain.

It was possible to drive to the intersection of the Brewer Creek Road and Military Pass Road today. The riding on the Brewer Creek road to the trailhead was easy going. Coverage is very thin below 6,000ft, though. The height of snow ranged from 30-100cm between 6,500-9,500ft on the Brewer Creek road up to the base of the Hotlum-Wintun Snowfield.
Between 6,5000-7,800ft on north and east aspects, 20-25cm of low-density snow (the December 3rd and December 20th storms) sits on top of the Thanksgiving rain crust. These specific areas are shady, cold, and wind-protected and have preserved the December snow, and have kept it light and dry. Below treeline on north and east aspects, the top 20-25cm of the snowpack has also started to facet. This recycled powder made for fun turns in the trees.
The Thanksgiving rain crust is rockhard, and has locked up the lower snowpack. Near and above treeline, this rain crust is the most widespread snow surface and is very firm and icy. Skiing and riding conditions were very poor above treeline today.
No signs of instability were observed.
