"Very large and destructive deep slab just north of emigrant peak on a east-facing aspect. The debris likely ran over 1000 vertical feet and stopped towards the bottom right of the image. We think the smaller slide on the far right was triggered as a secondary slide as a result." Photo: T. Papritz

A skier near Paradise Valley "... noted some recent dry slab (I'd wager within the last 3 days/warm-up) activity above Green and Blue gullies up Pine Creek." Photo: G. Antonioli

The deepest part of the crown was estimated to be 10-12' deep. It was a steep and heavily wind-loaded with a rocky starting zone.  Photo: GNFAC

The avalanche was powerful and put debris far down the slope along the flat bench. Photo: GNFAC

These 4 avalanches seem to have run at the same time (estimated 15 or 16 February) although the crown does not connect them, but the weak layer of depth hoar surely does. Slides 1 and 2 merged into the huge debris field. Photo: GNFAC

I measured the Alpha Angle (angle from crown to toe of debris) at 16 degrees. This is a very low angle that signifies the avalanche ran about as far as it ever could based on the size of the path. I took 5 measurements using 2 inclinometers to make sure this was correct. Photo: GNFAC
