About 300 feet down from the top of the couloir the 2nd skier of a group of 4 on a ski cut released a R2.5, D2 slide that went wall to wall in the main shoot of the couloir and ran for most of the path stopping midway in the runout zone. Crown height varied from 4" to 16" inches and averaged around 8" and debris in the toe was an estimated 3-4 feet deep. Failed on the new/old snow interface. Hard 1-2" windslab was the bed surface and we kicked off a few very small hardslab pockets when skiing the bed surface post main slide. Good anchor points and skiing 1 at a time led to no injuries and fortunately no one being caught in the slide.
Poor visablilty that cleared about 20 minutes post slide, cold north upslope light to moderate wind.
