Scofield Mine Blows: 200 Lives Lost in Tragedy

The blast reached the surface as a column of flame and debris that shot from the mine entrance and scattered timbers across the mountainside. At 10:28 on the morning of May 1, 1900, an explosion ripped through Mine Number Four of the Winter Quarters complex in Scofield, Utah, killing over 200 miners in what remains one of the deadliest industrial disasters in American history. Scofield was a company town owned by the Pleasant Valley Coal Company, which supplied fuel to the Union Pacific Railroad. The mine employed virtually every working-age man in the community. Miners entered the tunnels at 10:24, just four minutes before the explosion. The blast was caused by coal dust ignited either by a blown-out blasting charge or an open flame, though the exact trigger was never determined. The explosion's force was so violent that it reversed airflow through connecting tunnels and killed miners in the adjacent Mine Number One, nearly half a mile away. Rescue teams found bodies in clusters, some still holding lunch pails. Many victims showed no burns or injuries; they had suffocated on afterdamp, the toxic mixture of carbon monoxide and carbon dioxide that fills mines after an explosion. Of the town's roughly 1,800 residents, 200 men and boys died. Some families lost every male member. The youngest victim was fourteen. Every household in Scofield was directly affected, and the funeral processions continued for days. The disaster left over a hundred widows and several hundred orphaned children in a community with no other economic base. The tragedy prompted Utah to create the State Mine Inspector's office and pass new ventilation requirements. Similar reforms followed in other mining states, though enforcement remained weak for decades. The Scofield cemetery, where victims are buried in long rows, is now a state memorial.
