The Scofield Mine disaster kills over 200 men in Scofield, Utah in what is to date the fifth-worst mining accident in United States history.

The Scofield Mine disaster is one of the deadliest mining accidents in American history. It occurred on May 1, 1900, at the Winter Quarters coal mine near Scofield, Utah. The disaster was caused by a massive explosion believed to have been triggered by an overcharged mine blast igniting coal dust or methane gas.

The explosion was so powerful that it reportedly ejected debris from the mine entrance and could be felt up to 18 miles away. Approximately 200 men were working in the mine at the time of the explosion, and about 200 of them died as a result of the blast or from suffocation due to the afterdamp, a toxic mixture of gases left in a mine following an explosion.

The majority of the miners were immigrants from various countries, including Italy, Finland, and Greece, which added to the tragedy as many families lost their primary breadwinners. The disaster had a significant impact on mining safety regulations and led to changes in laws governing mine safety.

The Scofield Mine disaster remains a poignant reminder of the dangers of mining during the early 20th century and the need for stringent safety measures in industrial operations.
