2nd avalanche victim identified

The skier killed in an avalanche near Revelstoke, B.C., has been identified as Ronald Greg Sheardown, 45, an Ontario native who had been working in Dubai, RCMP said Sunday.

Sheardown, who was from Stouffville, was on a heli-skiing excursion with 10 other skiers and a guide from Canadian Mountain Holidays when the avalanche struck Friday afternoon.

RCMP have said a skier triggered the avalanche as the group came down the Selkirk range, about 35 kilometres southeast of Revelstoke. Three of the four skiers who were buried escaped, but Sheardown was not responsive by the time he was reached and died later in hospital.

The B.C. Coroner's Service is investigating, with help from the Revelstoke RCMP. An autopsy is scheduled to be performed on Tuesday, according to Sheardown's mother, Patricia Naccarato.

Described as dedicated father

Sheardown's wife, Cindy, and their three sons are flying in from Dubai to attend a funeral, to be held Friday or Saturday in Bolton, Ont., according to family members.

Michelle Sheardown-Tanzos, his sister, told CBC News her brother was an avid golfer and had been on the ski trip with his friends and colleagues. She said it wasn't his first heli-skiing excursion.

Sheardown was described as a "wonderful" and supportive father who spoke with his children several times a day no matter where he was in the world.

Sheardown was the second back-country skier to be killed by an avalanche this week. Duncan MacKenzie, 30, died after being injured in an avalanche and trapped in the mountains for much of the night near Pemberton, B.C.
