Accident and Rescue Summary

Details are still being sifted through, but what we know is this- a father and his three sons left the Bear River Service trailhead and rode their snowmobiles towards the Moffit Basin and ultimately landed near Yamaha Hill.

Hayden Ellingford waited at the bottom of the slope as one of the riders from the group took a bite low on the slope above him, triggering a large avalanche.

An organized outside rescue party found the man at approx. 17:54. He was not wearing a beacon nor did any members in his party have rescue equipment.
