A series of wildfires, started by lightning strikes the weekend of August 21–22, 2010, has burned over 300,000 acres of sage and grasses in the south-central region of Idaho. On August 23, the fire burned over 200,000 acres in a single day. Smoke from the fires has had a dramatic negative effect on air quality in a number of regional communities.
Landsat satellite imagery, acquired and processed by the U.S. Geological Survey and provided to the fire suppressant crews, marks the extent of the fires. The July 24 image shows burn marks from earlier, smaller fires; the August 25 image shows the dark tone of the large fire scar. Fire teams and regional vegetation management parties will use the imagery to track the fire and to plan rehabilitation of the areas affected.
