Likely triggered by cornice fall Thursday. mid-morning as Mark White walked through the area earlier that morning and saw no avalanche in the terrain noted here. Facets the culprit beneath 12-18" of storm snow. 1" pencil wind slab sits just above the faceted grains. Cornice piece noted adjacent to the slide. Below Wyatt Couloir
Of note, found full propagation adjacent to the crown 10cm down within the faceted snow. Faceted snow .5mm and damp. Probed length of the crown and found average 200cm depth snowpack there - not a thin weak spot trigger. Dug at lower Cardiac Bowl rollover and saw similar structure....though slab was 50cm, facets not as weak - ECTN
Ski and snowboard tracks litter representative terrain with completely different results....
This avalanche NOT one as reported from yesterday (or as I relay via the video....) New slide - Thursday midday cornice fall triggered natural -
