California Wildfire Burn Scar Spotted from Space

The Bagley fire, which charred 72 square miles (186 square kilometers) of the Shasta-Trinity National Forest near Big Bend, Calif., this summer, left quite a mark on the landscape.

NASA's Earth Observing-1 (EO-1) satellite took these images — one in natural color and one in false-color — of the scar on Sept. 11. The natural color image shows burned areas as bare brown spots of exposed earth. These appear red in the false-color image. Clear-cutting created the checkered pattern in the forests that can be seen in the lower-right of each image.

It's been a bad year for wildfires in the United States, partially due to the intense drought gripping much of the country.

The size and frequency of wildfires has increased significantly in the western United States over the last few decades due to climate change and changing forestry practices, according to NASA. Climate change has decreased winter snow cover, quickened the arrival of spring and intensified heat waves in the region — all of which add to fire risk.

Decades of fire suppression have also left denser forests and abundant fuel on the ground that cause fires to spread easily.

There are currently 27 large fires burning across seven states, according to the National Interagency Fire Center. As of today, fires have chewed through 13,094 square miles (33.913 square km). That's above the 10-year average for this date, which is 10,119 square miles (26,207 square km).
