Avalanche Details

This was a 2-3' deep slab avalanche that was triggered by a snowmachiner on the slope when they had just pivoted around to come back down the slope and came off their machine. The slab broke and drug both the rider and machine down to where the debris stopped. The rider was fully buried. The snowmachine was visible in the debris.

Rescue events

The two other riders in the group made their way quickly to the machine in the debris and began digging with their hands. There were two others in a different group who observed the slide and quickly were on scene to assist. They began a beacon search and did not find a signal. At that point they took their shovels out and helped the other two dig near the machine where a boot was seen. Within a minute the riders helmet was located and they were able to clear the snow around their head and mouth. The rider was breathing and alert. It took another 5 or so minutes to free the rider. They were uninjured and able to ride their machine after the incident.
