Difficult to determine previous snowfall amount and current rate due to strong winds and redistribution. Currently about S4, extensive drifting and most surfaces were low density and had a high possibility of more transport (Ski pen was approx 20cm).
Two avalanches were seen on small road cuts just below Heather Meadows- likely occurring when the bottom was undercut with a plow. Failure depths were about 20cm.
Was unable to cause avalanches on test slopes due to small, supported nature (cracking occurred), but was able to trigger one D1.5 avalanche on a larger, unsupported slope with a hard push from the top. The cracking and avalanches occurred in wind-loaded areas.
Poor visibility made it difficult to see if any natural avalanches had occurred.
An obvious weakness was present in a storm layer change about 20cm down from the surface. This was surprisingly consistent considering the extensive wind transport past and current. Cracking easily occurred on wind lips and on skin track tests (see photo). Several hand shears revealed the same weakness, several times failing on isolation.
A pit on Austin Pass yielded a 270cm snowpack. The only stability test result yielded the same failures as what we'd been seeing in the surface layers while traveling- CT11RP 20cm down. The Solstice Crust was 120cm down from the surface, and was a thin (1cm) P+ crust, which we could not get a result on in a deep tap test. ECTX.
Layer Depth/Date: 20cm
Comments: Travel was limited but suspect similarities at all other aspects and elevations. Failures occurred or were suspect in all areas we traveled on steep, unsupported wind-loaded slopes. Appears to be rapidly strengthening.
