Columns of thick smoke unfurled from forest fires burning across Idaho, Montana, and Wyoming and spread eastward across the plains at the foothills of the Northern Rocky Mountain on13 August 2007. This image of area was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Aqua satellite at 2:00 p.m. local time (U.S. Mountain Daylight Time). Locations where the sensor detected active fire are outlined in red. Fires are especially active in the Frank Church River of No Return Wilderness Area south of Idahos Salmon River. Gray-brown smoke cuts a diagonal swath across the center of the image. Smoke from these fires has been crossing the United States off and on throughout August, degrading air quality as far away as the EastCoast.
