(NIOSH). On February 27, 1943, at approximately 9:37 a.m., an explosion ripped through Smith Mine No. 3, a coal mine located between the towns of Bearcreek and Washoe. Since it was a Saturday, there was a short crew in the mine. Of the 77 men working that day, only three got out of the mine alive, and one of the rescue workers died soon afterward.

gas in the mine. The explosion was deep underground, and was not heard at the mouth of the mine, despite having enough power to knock a 20-ton locomotive off its tracks 0.25 mile (0.4 km) from the blast origin. All of the bodies were removed from the mine. There is a highway plaque near the mouth of the mine, which was never reopened, and there are memorials in the cemeteries in Bearcreek and nearby Red Lodge, the county seat for Carbon County. The explosion was attributed to a build-up of methane gas in the mine. The cause of detonation is unknown, but various reports note that men were allowed to smoke in the mine, and that fuses for blasting were lit with matches. The site of the disaster is included in the Smith Mine Historic District, listed on the
