The National Park Service recorded audio of flames spreading at the heel, or the back side, of the Maple Fire August 8, 2016 in Yellowstone National Park. Recorded from about 15 feet away, the fire activity was not extremely intense, but at about 14 seconds, you’ll hear a small clump of lodgepole pine trees burst into flames, or “torch.” In listening to the 60-second audio file below, you might want to turn up the volume.
The Maple Fire burned over 40,000 acres northeast of West Yellowstone, Montana.
