A river of thick smoke poured across central Canada on July 14, 2010. This image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite shows parts of northern Alberta (left), Saskatchewan (right), and the Northwest Territories (top) shrouded in yellowish gray smoke. East of Lake Athabasca, the actively burning locations of a large wildfire are outlined in red. Additional fires were burning in Alberta south of the area shown in this image.
