Dec. 21, 2017, 10:30 a.m. PST

Weather: Sky BRK; no ppt, T=-10; Wind=calm (and did pick up to gusting in the afternoon; Blow snow; none (but previous above 4500ft); HST 10cm; ski pen 30cm; boot pen 50+. HS 120cm

Snowpack: Average HS=120cm. We observed a right side up snowpack in the storm snow on top of the 12/15 crust 40cm down. Inter-storm layers are losing sensitivity in till tests. CTH-SP down 40cm below the crust 12/15 crust was the most consistent result (x4) in tests. One test resulted just below the T-day crust 60cm lower density rounds.

Area Description: BTL-Glades near the HwY 20 below the Delancy Ridge. Weather Obs in flat terrain on below S-facing aspect; el. 3590ft. Pit tests performed 1000ft higher on S-aspect rib @ 4600ft
