A combination of lightning, drought and human activity caused fires to scorch more than one-third of Yellowstone National Park in the summer of 1988. Within a year, burn scars cast a sharp outline on the 793,880 acres affected by fire, distinguishing wide sections of recovering forest, meadows, grasslands and wetlands from unburned areas of the park. After more than two decades, satellite instruments can still detect these scars from space. In the time-lapse video below, a collection of false-color images collected by USGS-NASA Landsat satellites from 1987 to 2011 show the burning and gradual regeneration of Yellowstone following the 1988 fire season. Watch as burn scars (dark red) quickly replace large expanses of healthy green vegetation (dark green) by 1989. Notice how the scars slowly fade over time as new vegetation begins to grow and heal the landscape.

New burn scars (dark red) created by less severe fires over the years can be seen in addition to the scars left behind by the 1988 fire season.

NASA Landsat project scientist Jeff Masek talks about the recovery of Yellowstone and how Landsat satellites detect its burn scars from space.

This multi-colored animation shows the different fires that ignited, combined and spread throughout Yellowstone from Jun. 30 to Oct. 2, 1988.
