Experienced Calgary mountaineer dies in climbing accident on B.C.'s Mount Robson

VANCOUVER - A Calgary man has been identified as the climber killed during a recent expedition on Mount Robson.

The B.C. Coroners Service says 35-year-old Bradley Charles Joyce died Aug. 20 while climbing the challenging back side of the mountain.

The peak is the highest, and one of the most difficult in the Canadian Rockies, about 100 kilometres west of Jasper.

Rescuers say Joyce, an experienced mountaineer, was crossing a snow bridge when it collapsed, hurling him into a crevasse where he was covered by a small avalanche.

Joyce's climbing partner called for help, but teams could not reach the victim in time.

The coroner says the death remains under investigation.
