The Castle Gate mine disaster occurred on March 8, 1924, in a coal mine near the town of Castle Gate, Utah (now dismantled), located approximately 90 miles (140 km) southeast of Salt Lake City. All of the 171 men working in the mine were killed in the series of three violent explosions. One worker, the leader of the rescue crew, died from carbon monoxide inhalation while attempting to reach the victims shortly after the explosion.
At least 24 out of the mine's 25 mules died in the explosion, along with an unknown number of horses and canaries. Additionally, rescuers commandeered about 20 of the community's pet birds to use as poison gas level detectors during the rescue and recovery efforts. They had an additional 30 canaries shipped in overnight. About 16 canaries died in the process.
