A large brush fire in southern Washington state burned over 150,000 acres on June 28th and 29th, 2000. Ignited by a car crash, the fire was burning near the Hanford nuclear reservation, although it had not released any radioactivity by afternoon on the 29th.
The image above was aquired by a NOAA Geostationary Operational Environmental Satellite (GOES) at 4:30 PDT June 28, 2000. The smoke plume was relatively small and thin compared to a forest fire of the same size.
