It鈥檚 believed the hikers fell onto debris from an earlier avalanche after stepping out onto overhanging snow and ice that gave way.

Choi and the other victims were members of a hiking club and were carrying whistles and a GPS beacon, but not full avalanche gear.

鈥淩eally, for this mountain, for this time of year at that height, they should have had full avalanche gear,鈥� Search Manager Martin Colwell, of Lions Bay Search and Rescue told CTV News.

鈥淭hey should have had avalanche beacons, shovels, and probes, per our normal advice to the public.鈥�

In addition to Lions Bay Search and Rescue, groups from North Shore, Squamish, Coquitlam, Mission, and Chilliwack Search and Rescue organizations were involved, as well as the Squamish RCMP.

Avalanche Canada has a 鈥渃onsiderable鈥� danger rating for the region.
