Numerous large and smoky fires were burning in northeastern Alberta and northwestern Saskatchewan on June 26, 2006, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite passed overhead and collected this image. Places where MODIS detected actively burning fires are marked in red. Fires surround Lake Athabasca and appear south of Reindeer Lake as well. Thick smoke has spread several hundred kilometers southeast toward Manitoba’s Lake Winnipeg.
