A group of five snowmobilers was riding in Antoine Basin near Reco Mountain. Late in the day one of the five triggered and was caught in an avalanche. The other members of the party were located in a safe spot at the side of the slope and were not affected by the avalanche.
The slide ran 150-200m downslope onto a flat bench that acted as a terrain trap resulting in a burial depth of over 300cm. The unaffected group members carried out a companion rescue but unfortunately the person caught in the avalanche did not survive.
