We observed this slide running off Seattle Ridge at 1:57pm. Shortly thereafter a snowmachine was spotted on the ridge above the slide. So, we think this could have been remotely triggered.

Broken to partly cloudy skies. Wind transport at ridgetops in AM, but fairly quickly went away. Warm day with air temps on routes near freezing. Calm winds at all locations on route.
Melt freeze crust to 1700', then soft new snow above 1700'. Near surface faceting on crust as well as in higher elevations.
Storm snow is settling, however our layer of concern (New Year's Eve buried surface hoar) had easy test results (CT9 Q2, ECTP11, PST 45/100 End). The depth of the New Year's eve buried surface hoar ranged from 50cm to 115cm at treeline.
