Thought this avalanche might be of interests even though it’s across the state line. We came across this avalanche skiing yesterday (03/03), looked recent to me. I included a few photos and a kmz file of the location.
Dug a pit at about a 10-15 degree angle, attempted my first isolated column with a ski edge, column slide during the isolation process. More carefully attempted a second isolated column this time the column didn’t slide until the second elbow tap. The shear layer appeared to be caused by a hoar frost layer about an inch thick (approximately at a 30” depth). The Slide appeared to be on not much more then a 25 degree angle, NE aspect, with no signs of human triggering. I was amazed this slope went.
