Environmental Impacts:

  • Fire season is winding down in western North America, but this false-color image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite reveals the season’s fire-scarred landscape.

  • Vegetation is in shades of green, while burned areas are red. Scars dot the Northern Rockies from Canada (roughly top half of image) to Montana (bottom right) and Idaho, to its west. Additional large scars are visible in the Coast Mountains (left) which stretch from British Columbia, Canada, southward into Washington. Clouds are white and light blue, lakes and rivers are dark blue, and snow is bright blue. Naturally bare ground (or extremely low vegetation), such as on the highest mountains ridges at top center, or in the Columbia River Basin (bottom center), is pinkish tan.

  • The worst forest fires in 50 years raged over a wide area of the Canadian provinces of Alberta and British Columbia after ravaging more than 54,000 hectares (133,000 acres) and destroying dozens of homes.
