Subject: Anthracites

Aspect: North, North East, South

Elevation: 10000-11400

Avalanches: 1-3″ storm slabs breaking on N/NE terrain >35°. Did not appear to be breaking into previous day’s snowfall.

Weather: Snowing s1 with short periods of s2. Ridge top winds out of S/SW. Wind was moving enough snow to cover parts of skin track on the ridge in-between laps.

Snowpack: HST ~6cm today before 2pm. South facing slopes had thin 1cm zipper crust from yesterday under new snow. Thicker ~2cm crust was present ~15cm below yesterday’s crust. Cracking was observed in today’s storm snow, on North facing terrain and did move as small sloughs/storm slabs in steeper terrain. Storm snow instabilities seemed to be limited to today’s snowfall.
