On September 6, 2003, dozens of large fires were burning in the northern Rockies of British Columbia (top), Montana (bottom right), Idaho (bottom center), and Washington (bottom left). In Montana, a line of fires stretches southward from the U.S.-Canada border for 190 kilometers (118 miles), creating a wall of smoke that hangs over the Lewis Range Mountains east of Flathead Lake. This image of the fires (marked in red) was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite on September 6.
