Drought conditions also have helped spawn forest fires.  In 1894 the Great Hinckley Fire destroyed Hinckley killing an estimated 459 people, and in 1918 a forest fire killed 453 people in the vicinity of Cloquet. More recently, in 2006, the Cavity Lake Fire burned 31,830 acres (129&nbsp;km2) in the Boundary Waters Canoe Area Wilderness.
