Snowpack continues to weaken, widespread surface hoar growth found up to about 7,500' along drainage. Old snow from October at the base of the snowpack kept me out of terrain holding this snow. This snowpack will not hold up well to a loading event.
Afternoon weather obs: Inversion persisting throughout the day. Calm wind. Band of stratus ~20 miles to the west, clear locally.

Intense faceting and SH growth at lower and middle elevations, below the inversion. Less pronounced but still obvious up high. Dug on NE at 7,800' trying to put a lower bound on October snow. HS=80cm. No October snow found here but lower 2-4cm of snowpack trending towards DH, which was moist where I dug. 11/17 presented as 1F crust with facets underneath. Probably some faceting going on above the crust too but less obvious than underneath. 1-2mm SH buried at 11/25 interface, down 7cm. ECTN 5 on 11/25 (down 7cm) and ECTN 17 on 11/17 (down 40cm).
Did not directly encounter avalanche problems. Avoided terrain where October snow was buried at the base of the snowpack. Skiers on NE side of Copper had entered this terrain with no obvious results.
