Ravensdale was originally called "Leary", after the Leary Coal Company, in turn named for John Leary, a Seattle coal speculator. The later name came from the flocks of ravens that fed on grain spilled from the boxcars on the Northern Pacific Railroad tracks that ran through the town. Underground coal mining commenced around 1899 by the Seattle and San Francisco Railway and Navigation Company, although coal had been mined in nearby Danville and Landsburg a few years earlier. The coal mines were later acquired by the Northwest Improvement Company (NWI), a subsidiary of Northern Pacific. In 1907, Ravensdale was a coal mining town with a population of about 1,000 residents, most of whom worked for the mining company. Ravensdale was officially incorporated on August 15, 1913. On November 16, 1915, at 1:25 p.m. an explosion occurred at the mine, killing 31 men, one of the worst coal mining accidents in Washington state history. The NWI mine was closed permanently and many of the immigrant miners left town seeking work elsewhere. A number of coal miners from Ravensdale moved to Ray, Arizona, to mine copper. The town was disincorporated in the 1920s.
Over the decades, coal mining continued to fuel Ravensdale's economy as new mines were developed operating on the Danville, Landsburg, and McKay coal seams. The Dale Coal Company became one of the more successful from about 1924-1941, followed by the Continental Coal Company from 1942–1944, the Anderson Coal Company from 1943–1948; and Palmer Coking Coal Company from 1937-1975. On January 29, 1955, four miners were lost in the Landsburg mine when a cave-in filled the mine with water, mud and debris. On December 17, 1975, at 2:30 p.m., the Rogers No. 3 mine was dynamited shut by Palmer Coking Coal Company. This was the last underground coal mine in the state of Washington.
