Ribbons of smoke from fires in Alaska and northern Canada swirl over the Gulf of Alaska (lower left) and British Columbia (lower right) on August 15, 2004. The image is a combination of three Moderate Resolution Imaging Spectroradiometer (MODIS) images on that day: two from MODIS on the Aqua satellite, and one from the MODIS on the Terra satellite. Actively burning fires have been marked with red dots in the image.
