This is the scar left by the horrible Waldo Canyon Fire that burned through 18,247 acres (74sqkm) in Pike National Forest. With 346 homes incinerated, two lives lost and hundreds of millions of dollars in damage, it was the most destructive fire in Colorado history.
This image was captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite on July 4, 2012. It's a false-colour image — the bright red means untouched forest, light brown means some burning, and dark brown indicates severely burnt areas. [Flickr]
