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

~35F at the road, cooling to around 25F at 3800ft. Winds around 10mph from the West.

Snow surface

Many wind slabs on west aspect slopes, less than 30cm in depth, pencil hard on loose faceted snow near the ground, about 10cm in depth. Drainages were filled in with wind deposited snow and old settled snow, varying between 70-110cm in depth.


Dug two pits at 3200ft on a WSW aspect in a deeper wind loaded area.

Pit 1: Snow depth - 70cm, ECTN 21, collapse 30cm from top on wind/old snow interface, 20cm wide. After hammering shovel beyond ECT, propagated on faceted snow 10cm from ground.

Pit 2: Snow depth - 110cm, ECTN 21, collapse 40cm from top on wind/old snow interface, 30cm wide, propagated after heavy prying behind ECT column on same layer as pit 1.
