Snowmobilers gather at the scene of an avalanche shortly after it hit near Revelstoke, B.C.Steve Langevin
Saturday's avalanche in Revelstoke killed two and injured 30 as a wall of snow tore through an extreme-snowmobiling event. But the avalanche was not unexpected - explicit warnings were issued by the Canadian Avalanche Centre last week, advising that conditions across B.C.'s backcountry were unstable.
Is the answer education or regulation? How did the CAC manage to educate backcountry skiers about the risks - and will the same strategy work with snomobilers?
And what about the cost of rescuing those who go against advice and head into treacherous terrain? Should they be billed for search and rescue services? And why is it that extreme snowmobiling is banned completely from the federally run National Parks?
Karl Klassen is the CAC's Public Avalanche Bulletins Manager. He was joined by David Ebner, a Globe and Mail reporter and experienced backcountry skier, Tuesday to answer your questions. Read the earlier discussion here:
