The Granite Mountain/Speculator Mine Disaster of June 8, 1917 is one of the most momentous events in US mining history. In the depths of Butte, Montana's copper mine, tragedy unfolded that day as a fiery inferno engulfed the tunnels and filled them with searing smoke. The miners had been toiling away at full production to support America in World War I and were pushing for better working conditions. Little did they know that their efforts would be in vain, as 168 of them died that day due to suffocation from the fire consuming their oxygen supply. It was a devastating blow to Butte, Montana and the nation and stands today as one of the worst underground hard rock mining disasters in US history. Mining will never be the same.

A hundred years have passed since that fateful day, but its memory still lingers in Butte, and its legacy lives on as a reminder of the danger and sacrifice of mining. The Granite Mountain/Speculator Mine Disaster forever stands as a testament to those brave miners who gave their lives in service to their nation.
