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

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.


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".
