The BC Coroners Service says Steven Burke Hall of Birchcliff was among a party of six snowmobilers.
Three of them stopped for lunch while Hall and two others continued to ride uphill before the slide struck.
The avalanche came within hours of the Canadian Avalanche Centre issuing a warning that weak layers of snow presented a danger of large slides across much of southern B.C.
Friday's fatality is the second avalanche-related death in B.C. inside of a week.
A 44-year-old man from Squamish died last Tuesday after he and four other snowmobilers got caught in a snowslide near Whistler.
