2000 continues to be the worst fire season in the United States in decades. By August 8, 2000, fires in Montana and Idaho had burned more than 250,000 acres. Resources were stretched so thin that Army and Marine soldiers were recruited to help fight the fires. President Clinton visited Payette National Forest to lend moral support to the firefighters.Dense smoke from Idaho and western Montana is visible stretching all the way to North and South Dakota in this image from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS). The image was taken on August 7, 2000. Although the primary mission of SeaWiFS is to measure the biology of the ocean, it also provides stunning color imagery of the Earth's surface.For more information about fires in the U.S., visit the <a HREF="http://www.nifc.gov/" TARGET="outlink">National Interagency Fire Center.</a>To learn more about using satellites to monitor fires, visit <a HREF="/Library/GlobalFire/">Global Fire Monitoring</a> and <a HREF="/Study/Fire/">New Technology for Monitoring Fires from Space</a> in the Earth Observatory.
