According to the U.S. Department of Agriculture Forest Services Active Fire Mapping Program, roughly 40 wildfires greater than 2,500 hectares burned in Canada on 11 September 2006. Most of those fires were in western Canada. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Aqua satellite took this picture on 9 September. Although just two hotspots (readings of anomalously warm surface temperatures, indicated in red) appear in this image, a thick plume of smoke streaks its way up through Alberta into the Northwest Territories. The smoke plume is thickest in the center, gradually thinning out on either side.
