The Great Fire of 1910 (also commonly referred to as the Big Blowup or the Big Burn) was a wildfire that burned about three million acres (12,000 km², approximately the size of Connecticut) in northeast Washington, northern Idaho (the panhandle), and western Montana. The area burned included parts of the Bitterroot, Cabinet, Clearwater, Coeur d'Alene, Flathead, Kaniksu, Kootenai, Lewis and Clark, Lolo, and St. Joe national forests. The firestorm burned over two days (August 20–21, 1910), and killed 87 people,[2] including 78 firefighters.[3] It is believed to be the largest, although not the deadliest, fire in recorded U.S. history.[4]
