Today two of us skinned up a NE facing aspect and felt no instabilities besides ~10-12in of storm snow that easily sluffed off a slightly firm layer. It was fairly windy and high teens/low twenties Fahrenheit temp outside. After we rode down we noticed a large crown spanning ~800ft across the adjacent SE facing slope and ran about 1100ft. We saw two skiers come down from that run and leave on their snowmobiles. After ending our run we decided to skin up the skin track we saw leading up to the slide to inspect it. The track was covered at the base of the slide and it was apparent that the two skiers we saw leaving had recently triggered the slide and rode around the debris. The slide appears to have been triggered on the Jan 13 persistent weak layer.
