At 8:30 a.m. on March 8, 1924, an explosion in the Castle Gate No. 2 Mine, about one-half mile southeast of this site, instantly killed 171 miners. Rescue teams from surrounding mines rushed to Castle Gate and, wearing oxygen breathing apparatus, first explored the main haulage road but found no bodies. Crews then began repairs on the caved haulage road portal because gas was issuing from that point. During one of these exploration trips, George Wilson, age 29, married, captain of the Standardville No. 1 Rescue Team, was killed by inhaling carbon monoxide after removing his nose clip on the breathing apparatus. Most of the miners who died were immigrants. Fifty-seven were single and 115 were married, leaving 417 dependents, including 241 children and 25 expectant mothers. Nearly all of the miners were buried in the Price City Cemetery.
