Observer Comments
Several D1.5 and one D2 wind slab in steep terrain in Lynx Creek and west side of Captain's Chair. Shooting cracks easy to initiate in small wind loaded test slopes, up to 30' long.
Weather
NW winds gusting to 20s. Temps in the 20s mph. Clearing trend throughout the day.
Snow surface
Wind affect above ~ 1500' and anywhere out of the trees. In trees, still finding soft snow 6-10" deep on supportable slab.
Snowpack
Dug snowpits at ~ 2,000' in Lynx Creek.
HS: 240cm
East aspect
ECTN12, 22 down 20cm on density change. No propagation in snowpits and no failure deeper in the snowpack. This was pretty consistent with what we were seeing on test slopes and in the recent natural wind slabs. Small test slopes were easy to initiate shooting cracks. Most only ~10' long and breaking in the top 6-10".
D2 Natural wind slab at ~2500'. SW aspect, Captain's Chair. 02.27.2021
