Observer Comments

Had some settlement on flat areas at ridge line. Believe it was due to windslabs collapsing.

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

Comfortable on the ridgeline in the sun. Cold in the lower bowls which were shaded.

Snow surface

Faceted snow surface. Could feel a crust below the surface on a west aspect. A thin breakable crust on a lower east aspect.


CT20SP. ECTP14SP. Both collapsed and slid out 40 cm below the surface, 40degree slope, southwest facing with some possible old wind loading. Height of snow was 112cm, about 3,000 elevation. Looked for the BSH but wasn't as obvious compared to past pits. Maybe a reactive windslab instead.
