Quick report

We spent the afternoon glassing and taking photos of recent avalanches, all occurring over the last week, including a skier-triggered slide above Dehlia Creek. Late in the day, I walked to the crown of both that skier-triggered slide and a nearby natural one. On the walk up slopes below 2500' were isothermic wet snow, barely supportable on skis in shallower areas. As I climbed in elevation, the snowpack remained moist-wet at all elevations and aspects I traversed. Both avalanches failed within the new snow on a thin layer of graupel and gouged down into the entire season's snowpack. The outlier being portions of the skier-triggered slide that failed on facets below a stiff melt freeze crust—these facets were large and moist.
