During the summer of 1988, wildfires burned about 1.4 million acres in and around Yellowstone National Park. Spurred by the driest summer in park history, the fires started in early July and lasted until early October. The worst day was August 20, when tremendous winds pushed the fires to burn over 150,000 acres. Although the scars from these fires are still visible in Landsat imagery from space over ten years later, the patchwork nature of the fire footprint left many unburned areas from which plant species have regenerated very successfully. This animation shows how the fires progressed in the period from June 30 though October 2, 1988, by which time the fall rain and snow had stopped the fire growth. These maps are based on daily ground observations by fire lookouts in the park and by infrared imaging cameras flown over the park at night. These observations are considered accurate to within about 100 meters.
This animation shows the progression of the fires in and around Yellowstone National Park during the summer of 1988, overlayed on a false-color image from Landsat 7. Independent fires are shown in different colors, and the most recently burned areas are shown in a brighter color.
