I remotely triggered this avalanche in West Monitor a little after 1pm, I was walking up the ridgeline felt a collapse and watched a cornice release into the bowl triggering this fairly large avalanche. I put persistent weak layer because I’m fairly sure it broke into old snow by the size of the debris pile, some snapped trees and a big powder cloud. The slope has avalanched multiple times this year and was being heavily wind loaded throughout the day, I would classify it as a repeater. The crown was 2ft at its deepest point and the debris had more of the characteristics of a hard slab than a soft slab. It ran full track and quite a ways out on the flats.
