First big warming event since prior to the last storm cycle.
This small slide (D.5) slid on the rain/freeze layer. This is suspected to have initiated under a cornice forming on leeward terrain some time before noon. We do not think it was caused from cornice break.
ECTN 20 at the rain/freeze crust 20cm bellow surface. *This site experiences skier compaction, though the new snow fall from 1/6-7 had not yet seen skier traffic before this slid occurred.
My thoughts are that this wind slab was touchy in the am with cool overnight lows, then trended towards stable throughout the day with gradually warming temps.
