The Castle Gate mine disaster occurred on March 8, 1924, in a coal mine near the town of Castle Gate, Utah, 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.
Castle Gate is a ghost town in the western United States, located in Carbon County in eastern Utah. A mining town approximately ninety miles (140 km) southeast of Salt Lake City, its name was derived from a rock formation near the mouth of Price Canyon. This formation features two sheer sandstone walls on either side of the Price River, which appear to open like a giant gate as travelers approach this narrow section of the canyon.
