Notes
Loose snow avalanches were triggered easily from the ridgeline. These avalanches would start from new and wind-drifted snow but entrain larger amounts of snow from facet weak snow below. This resulted in gouging sluffs that were deeper than just new snow.

From Obs: "Loose snow avalanches were still sensitive to triggers. These avalanches would start in the new snow but entrain the weak faceted snow below resulting in larger avalanches than what recent storm snow could produce on its own." Photo: GNFAC
