New avalanche danger scale for 2010/11

In the past, skiers and boarders have had concerns about the ambiguity of the avalanche danger scale for Canada and the United States. Hopefully those concerns will be put to rest this coming season, as backcountry avalanche centers across North America will be using a new scale for 2010/11. The new scale provides more definitive travel advice for backcountry enthusiasts, incorporates risk by referring to typical avalanche sizes expected, and uses icons that have recently been adapted by European countries.

“It was especially encouraging to work closely with our Canadian colleagues to come up with a unified scale," said Grant Statham, project leader and Avalanche Risk Specialist for Parks Canada. "This will only help in our efforts to promote avalanche forecasting consistency and to improve safety for the many people who recreate in the backcountry in both countries.”

This danger scale is the first time that the two countries have used the same scale, and is the result of a multi-year effort by the Canadian Avalanche Centre, Parks Canada, the USDA Forest Service, and the Colorado Avalanche Information Center.
