The Dollar Mountain Fire was one of the earliest large scale wildfires in Ferry County, Washington, United States.

Starting on August 4, 1929, and burning an estimated 98,000–142,000 acres (400–570 km2) of Colville National Forest land in the Kettle River Range, east of Republic, Washington, the conflagration was contained by mid-September, but only finally extinguished due to weather changes late in the year.

Fire crews came from across the region, including Portland, Oregon, Seattle, and Spokane, Washington, and across British Columbia.

[2] The fire season of 1920 saw the largest acreage losses to that point in the Colville National Forest lands, with four large conflagrations.

1929 saw abnormally dry conditions across the region, the daily high winds blowing from the south exacerbating the 6% to 10% ambient humidity.

Further investigation pinned the start on careless campers who had been in the area at the time,[4] possibly either a smoker's or a blackberry pickers fire.

[5] In addition to the windy, hot, and dry conditions, the fire's behavior was unpredictable, with the forest service noting that single day "runs" of 5–6 mi (8.0–9.7 km) were not uncommon and that already burned areas were frequently reigniting.

A number of additional fire lookouts were approved and built along the backbone of the Kettles, which were seasonally or continuously manned until their eventual decommission.

Stations inaccessible to wheeled vehicles had the lumber and building material packed in by men and tandem-horse teams in custom made harnesses.

[2] Originally established in 1927 with 17,000 acres (6,900 ha) of national forest, the San Poil State Game Reserve was expanded after the Dollar Mountain Fire.

[12] In 1938 Civilian Conservation Corps workers living at Camp Growden were tasked with fire hazard mitigation and other cleanup work in the surrounding Dollar Mountain Burn.
