According to the July 23 report from the Canadian Forest Service, fire activity in the third week of July 2008 was near average. The number of fires was “typical,” and the area burned was just slightly above average. Nevertheless, fire danger was extreme in parts of the country, including across a swath of land stretching northeast from southern British Columbia to the Great Slave Lake region in the Northwest Territories.
