3,000 acres (1,200 ha) in ten minutes

The Mann Gulch fire was a wildfire reported on August 5, 1949, in a gulch located along the upper Missouri River in the Gates of the Mountains Wilderness, Helena National Forest, in the state of Montana in the United States. A team of 15 US Forest Service smokejumpers parachuted into the area on the afternoon of August 5, 1949, to fight a 50–60 acres (20–24 ha) lightning-caused blaze, assisted by a local recreation guard. As the team approached the fire, an unexpected change in wind direction caused the fire to ignite heavy fuels, creating a \"blowup\" and cutting off the men's escape route to the Missouri River. The crew was forced to retreat uphill into a lightly timbered area with a dense groundcover of extremely flammable grass and brush. The fire moved rapidly up the slope, burning 3,000 acres (1,200 ha) in ten minutes and claiming the lives of 13 firefighters, including 12 of the smokejumpers. Only three of the smokejumpers survived. The fire would continue for five more days before being controlled.
