Comments
Dropped a small, cornice, which remotely triggered two slides on Scott’s Bluff, the cornice did not trigger the area of the slope that it hit but remotely triggered a slide off the peak a couple hundred feet away then remotely triggered another avalanche at least 50 feet from the cornice drop. I’m going with persistent weak layer because it instantly stepped down to the facets at the ground. I only inspected the slide lower on the slope and it initially started in a thin rocky steep area where the crown was only a foot deep, but it pulled out to the ground leaving a 2 foot crown in the deepest part. The new snow cleaned out and ran a good ways on the flats but it left the 5 to 8 inches of faceted snow in the bed surface. Conditions were full on at this point and I didn’t inspect the slide off the peak. No one was in the area, and only took a small disturbance on the slope to produce remotely triggered avalanches
