The Knox Mine Disaster: The Day the River Came In
Near Scranton, Pennsylvania
On January twenty-second, nineteen fifty-nine, a hole opened in the floor of the Susquehanna River.
The Knox Coal Company had been mining anthracite beneath the river in Jenkins Township, just south of Scranton near Pittston, pushing tunnels ever closer to the surface in order to chase thin remaining coal seams. Mine maps were not being updated accurately. Company officials knew the rock ceiling above the workings was dangerously thin, perhaps as little as six to eight feet between the miners and the river bottom. They kept digging.
That January morning, the ceiling gave way. A hole estimated at one hundred fifty feet across opened in the riverbed, and ten billion gallons of water and ice began pouring into the mine gallery. Workers felt the rush of water and ran. Some made it out. Twelve did not.
The torrent spread through miles of interconnected tunnels beneath the Wyoming Valley, a vast underground network connecting mines across the region. It took three days to plug the hole, accomplished by dumping railroad cars, mine cars, coal waste, and debris into the whirlpool that had formed above the breach.
A note on the legal aftermath: the Knox disaster was investigated and prosecutions were brought against company officials for negligence and falsification of mine maps. The manslaughter charges against company officials were initially met with convictions, but those convictions were overturned on appeal. Separate convictions on bribery and tax evasion charges tied to the disaster did stand, and some officials served jail time. The precise details of the sentencing records are documented in court filings but some specifics remain difficult to independently verify across sources.
Within months of the disaster, major coal companies began withdrawing from anthracite mining in the region. By the nineteen seventies, underground anthracite mining in the northern field had effectively ended. The Knox disaster did not single-handedly kill the industry. But it put a catastrophic period on the sentence.
