Observer Comments

debris was extremely hard with many small layers that were appeared to be from heavy/rapid wind loading. Appeared to be a natural trigger, but could have been remotely triggered by a snow machine as there were tracks to skiers left and below the ridge line where this occurred. (This was right off the road)
