Comments
Observed avalanche from Brohm Ridge. Start zone was obscured but rumbling lasted over twenty seconds. Dry, suspect triggered by active wind loading. Not associated with yesterday's wet loose cycle below 1600m. Wind slab with entrained storm snow.
Powder cloud approx 200m high. Estimate debris as 80-110m wide, 500m long.
