Several territories in northern Canada are experiencing active fire seasons in 2004. This image of parts of the Northwest Territories (top), Saskatchewan (bottom left), and Manitoba (bottom right) on July 25, 2004, shows smoke billowing from multiple large fires southeast of Lake Athabasca, which straddles the border between Saskatchewan and Alberta (thin strip along left edge of image). The river of smoke flowing into this scene from the northwest comes from additional fires burning in the Northwest Territoreis, southeast of Great Slave Lake.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image along with active fire detections. Areas where MODIS detected fires are outlined in red. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.
