No obvious signs of instability

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Valley fog w/ clearing skies above 1400 ft, calm to light winds, temps low of 6F @ T pass (1,000') and 14F at 2000ft

Snow surface

10-20 cm ski penetration, surface hoar 3-6mm all the way to ridge line and preserved on solar aspects. Excellent skiing w/ lots of groups out pushing into bigger, steeper avalanche terrain with no results in terms of skier-triggered avalanches.


Thanksgiving rain crust in the mid pack disappears near 2500ft. Below this layer the base of the snowpack remains moist. Above 2500ft our Sunburst group found inconsistent results in snowpack tests. Basically a poor snowpack structure with basal facets BUT good stability. The HS remains 40-85cm above 2500ft.
