General Comments

The slide we triggered was in shallow rotten snow at the ridge top at 8,800 feet. While skinning, a massive collapse preceded the slide, 20 feet wide, running 80 linear feet, to the ground on depth hoar (~2 feet deep). It stopped on the flat terrain immeadiatly below. Minimal windloading here too. Previous collapses had been heard as well near the ridge. It was slow moving ,as the slope was barely over 30 degrees.
