On August 1, 2003, dozens of large fires were burning across western North America in Canada (top half of image) and the United States (bottom half). Huge plumes of smoke were streaming northeastward from massive fires in Canada’s British Columbia (left) and Alberta (right) provinces, while across the international border, fires were burning in (left to right) Washington, Idaho, and Montana. This image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite.
