Knox Mine Disaster
Near Scranton, Pennsylvania
On January twenty-second, nineteen fifty-nine, twelve men died when the Susquehanna River broke through the ceiling of the River Slope Mine near this site. The Knox Coal Company had illegally excavated tunnels directly beneath the riverbed, leaving a dangerously thin layer of rock between the miners and the ice-laden winter current above.
When that barrier gave way, more than ten billion gallons of water roared through this mine and connected workings throughout the Wyoming Valley. The disaster was not an act of nature but of deliberate lawbreaking, driven by pressure to extract every possible ton of coal regardless of the risk. The Knox Mine Disaster effectively ended deep-shaft anthracite mining across much of the Wyoming Valley, closing out an era that had defined this region for over a century. Twelve families were left to grieve what corporate negligence had taken.
