Comments
This seemed to have run 3/6 during AM high PI. Dimensions and other characteristics estimated but it was spectacularly well connected across the very steep rock slabs in the Icebox headwall (“Bluebell” as Athey would tell you). Heather posited that it could have failed on buried surface hoar that formed on Tuesday evening which seems plausible in this zone and may corroborate the connectedness. There were some other interesting new snow slides in the zone failing a little down off the ridges on slopes lee to the pre frontal wind direction. Pardon the heavy breathing in the vid.
