Utah Avalanche Center

Avalanche likely triggered by cornice fall, but snowbike and sled tracks in the area and some tracks taken out by the slide.

Crown of skier triggered slide on 3/8/2017. Obvious hard wind slab from downslope winds resting in softer snow. Bed surface was at 315cm. What was remarkable was the width of this slide. It was 250-300 feet wide and ran maybe 350 feet slope distance. The weak layer was primarily decomposing stellars, but they may have gotten just a touch faceted. I couldn't tell. Even on such a relatively hot day today, as the sun disappeared behind Mt. Superior, the temps started dropping quickly.

Just above Snotel site. Did not dig to ground. ECT - no results

Periods of very heavy snow. This pit near area where I triggered a storm slab on Monday that ran on the 2/10 rain-crust. Facets now 90 cm deep, rounding, and layer is much better bonded

I intentionally triggered a small storm slab on a very steep slope at 8300'. It failed on small faceted grains and ran on the thick 2/10 rain-crust.
