Observations

We had 1 person unintentionally trigger a D1 wind slab in flat light, observed 1 natural avalanche (photo) that was recent (>12 hrs), and triggered 2 other different D1 wind slabs on small test slopes (see photo) in the Salmon moraine area. New small wind slabs were more sensitive and a bit deeper in that area than we expected. These are multiple observations from 3 separate avalanche professionals instructing a Level 1 course in the area. The weather was variable but seemed like more snow and continued throughout the day compared to forecast. Winds were mostly as forecasted. Blustery and whiteout conditions sent us further downhill into the near treeline zone. The hazard seemed in alignment with forecast, but some of the slabs were very soft but more sensitive to triggering than expected. Also was surprised by the natural avalanche we observed. We were able to manage hazard easily because of its small size and its isolated terrain locations; and intentionally avoided vicinity to any steep leeward slopes

Did several snowpack pit tests.
Pit 1: 5622' , NE aspect, HS = 85 cm over 2/22 rain crust
CT25 (Brk) down 10 cm
ECTP17 down 10 cm

Pit 2: 5635', S aspect, multiple P/K crusts in top 40 cm
CT4 (PC) down 10 cm
