NASA | Satellites See Smoke Plume from Fourmile Canyon Fire

On the morning of September 6, 2010, a wildfire known as the Fourmile Canyon Fire broke out just west of Boulder, Colorado. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra and Aqua satellites captured these images of the Fourmile Canyon Fire and its resulting smoke plume on September 7th and 8th. The red outline corresponds with the unusually high surface temperatures associated with an active fire.
