Quick report

All things considered, the recent storm systems have provided a massive jump start to the winter season. Coverage on the south side of Mount Shasta is excellent, with little to no ground showing below 6,000 feet. At the moment, soft snow is still preserved at high elevations and shaded aspects. As the days continue to warm, a solar crust will develop across most aspects. 

No significant instabilities were observed.

A small avalanche was found in Old Ski Bowl. On the upper mountain, above 10,000 feet, wind textured surfaces could be seen across the majority of exposed slopes.

A beautifully clear day with calm wind and direct sunlight. A morning valley inversion kept temperatures colder than expected in town. By midday, however, temperatures climbed well above freezing.

Snowpack

Snow depths vary based on elevation. At 9,800 feet in Old Ski Bowl, the snowpack is 195 cm deep. At 7,800 feet, the snowpack is 150 cm deep. For the most part, the snowpack appears strong, and dense, with a series of crusts and soft snow. In the coming days, the surface snow will surely develop another solar crust as temperatures climb.

A small, D1 slab avalanche was found on a SE aspect of Green Butte, releasing into Old Ski Bowl. This was likely a lingering wind slab from the most recent storm event.
