A map of the 2004 fire season's effect on Alaska and the Yukon.
Graphs record the area burned and number of wildfires in Alaska from 1956 to 2004.
The 2004 Alaska fire season was the worst on record in terms of area burned by wildfires in the U.S. state of Alaska. Though there were fewer fires than in 1989 when almost 1,000 were recorded, more than 6,600,000 acres (27,000 km2) were burned by approximately 700 fires. The largest of these fires was the Taylor Complex Fire, which encompassed 1,700,000 acres (6,900 km2) and was the largest fire in the United States from 1997 to 2007. The Boundary Fire, Wolf Creek Fire, Chatanika Fire, and a fire that enveloped the Trans-Alaska Pipeline also received notable attention from firefighting services and the media. 426 fires were started by humans and 215 by lightning.
