23-24

From obs: "Towards the end of the day one of our riders remote triggered a massive avalanche on the North facing slope to the North of Yellow Mule cabin. The 3-4 ft crown propagated around 600 yards wide and slid on near ground facets to the bottom of the slope below depositing a very large debris pile well into the trees."

Observed cracking and whumping throughout the day. Towards the end of the day one of our riders remote triggered a massive avalanche on the North facing slope to the North of Yellow Mule cabin. The 3-4 ft crown propagated around 600 yards wide and slid on near ground facets to the bottom of the slope below depositing a very large debris pile well into the trees. 
 

No riders were caught and we inspected the debris pile after. Some of the touchiest avalanche conditions we’ve ever been out in. The meadows were riding nice, I would suggest sticking to them and well away from any steep slopes.
