Around 10am on September 6th, the Fourmile Canyon Fire started out just west of Boulder Colorado, and continues to burn hot.  NASA has released an image of the fire from their Terra satellite.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image of the fire at 12:15 p.m. local time (18:15 UTC) on September 6, 2010. The red outline corresponds with the unusually high surface temperatures associated with an active fire. A river of thick smoke flows eastward. Over the plains northeast of Denver, the smoke plume casts a shadow to the north.

Boulder County has issued a public health alert, and so far 12 homes and 3000 acres have burnt.
