Avalanche Location:
Triggered by our party with ski cuts, or in 1 case, triggered by another party. East-northeast facting slopes. Slabs soft and thin but propagated widely - full width of start zones. 5-7" thick. Seemed like maybe a thin layer of near-surface facets at the failure plane. All slides within 150 vertical feet of ridge or in wind-affected area near the notch. All on slopes > 35*.
