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

Partly cloudy. Light breeze throughout the day. Temps are slightly above freezing all day.

Snow surface

5-10cm of new snow on top of a harder faceted layer- and in some locations MF crust.


All of us had reactivity between the new snow interface with the faceted layer beneath roughly 5-10 cm down from the snow surface. We also had reactivity on the basal facets. One instructor's pit results were CT13SP (on the new snow and facet layer), CT23SP and ECTP27 (on the basal facets) with a snow height of 65 cm.
