Comments:

Visual obs from the air, hard to tell crown depth guessing 60cm. This was a series of 3 slides that could have occurred independently or released sympathetically - Largest slide ran around 900' vertical from steep terrain that was wind-loaded at the top but had a secondary component break out lower down in protected trees. Second slide could was limited do to terrain size but looked to break out in cross loaded, rocky feature.
