This little avalanche path is a "frequent offender" as it crosses the Pleasant Creek road about once a year. I was a little surprised that it released during the last storm although we did experience strong wind which was no doubt a major contributing factor. I suspect this broke into a "persistent weak layer" of faceted sugar snow that formed in mid December. We did not get up to the fracture line so this is only conjecture but it certainly looks like this slide fits the pattern with everything else I've been seeing.

The debris on the road and below the road into the gully was 8 to perhaps 10 feet deep.
