Scary example of Persistent Weak layers we've been talking about since early Feb. Exact weakness is unknown, but this one took out a significant amount of old snow. triggered in a thinner snowpack area near Ridge on an ENE facing slope that approached 40 degrees and averaged 35 degrees. Slab was 2-5 feet deep and appx. 600 YARDS wide. Slide ran about 1500 vertical feet. Thanks to Pat Lambrose for this observation.
