From obs: "the whumpf I had heard previously remotely triggered a series of 7-8 large cracks that ranged from 30-100 feet wide. ... As I carefully descended the meadow, I saw many more cracks throughout the slope from the same remote trigger event. Additionally, I triggered two more significant whumpfs with shooting cracks 10-40 feet wide. We determined our remote trigger was at least 300 feet away from where the snow collapsed and cracked"
