Fast-moving forest fires raced through Glacier National Park in northwest Montana on July 25, 2003. The fires (marked in red) forced thousands of tourists and staff to evacuate the park (image center). This image of the fires was captured on July 25, 2003, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite.
