Two days after an avalanche claimed the lives of two snowmobilers and injured several others in dangerous conditions near Revelstoke in British Columbia, Canada, the head of the B.C. Snowmobile Federation said stronger regulations are not needed.

"Right now it's a personal choice," Les Austin, the group's executive director, told the Vancouver Sun. "I don't believe there needs to be greater regulation. We need greater education and stuff like that so people can make better-informed decisions. That doesn't happen overnight."

The incident itself, unfortunately, should serve as a reminder for snowmobilers, whose heavy machinery can trigger avalanches when danger is present, to heed avalanche warnings.

The danger was clearly present when the group took to the slopes of Boulder Mountain for a controversial extreme snowmobiling event after heavy snowfall.

The avalanche was massive and hurled some of the snowmobiles more than 500 feet, prompting a large-scale rescue effort.

While some are callIng for more regulations, Austin implied it should be up to individuals to assess risk and act accordingly.

"Every one of them made that personal choice," he said. "These are personal decisions people made to go to something like that. The warnings were definitely up.

"If I go riding with my friends I make sure they've got the [avalanche rescue] equipment and know how to use it. It's my decision if I climb the hill or do whatever. It's their personal decision to do the same."
