Snowpack

We were able to pop out small wind slabs on several test slopes, 4-16" slabs sitting on hard bed surface with facets/surface hoar in between. After small slabs popped out you could see the sparkling facets/surface hoar on bed surface. We did not see any evidence of large avalanches. In a pit we got CT15RP and ECTN15 on the faceted layer down roughly 30cm. See photos for profile.
