Conrow Fire

The Conrow Fire was started by a lightning strike on August 24, 2017, on private land seven miles northeast of Whitehall, Montana.^[2] By August 27, the fire had grown to 2,727 acres (11 km²) and had moved onto Bureau of Land Management and United States Forest Service land in Jefferson County. The fire threatened 25 structures, including cellphone towers, mining areas, homes and cattle ranches along the Highway 69 corridor.^[3]

By the next day, the fire threatened one more structure, totaling 26 and structure assessments began in the Antelope Lane area.^[4] On August 28, a containment date of September 2 was set and two Chinook helicopters joined the firefight, dropping water on the fire.^[5] The fire began to dramatically impact air quality, with the help of other fires burning in the area, including creating the worst air quality day in two years in Butte.^[6] On August 30 the fire was declared 65% contained at 2,727 acres (11 km²).^[7][8] Crews changed the full containment date from September 1 to September 6.^[7]

As of September 5, the fire expanded to 2,741 acres (11 km²) and was 97% contained, with fire lines successfully holding the fire, despite the fire's close proximity to unburned fuels.^[9]
