Bridger Range, 2021-01-08

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"

"Big shooting crack across the south facing path from the skin track so expected the east bowl to remotely trigger and it did from 25m away on the ridge. R3D2 slide. Confirms all previous regional reports and the concerns of the day, typical in this specific area early season. Obsessive terrain management is the only way just now." Photo: Anon
