On a freezing morning in January 1959, residents of Pittston, Pennsylvania, looked out at the Susquehanna River and saw something that looked like a scene from a disaster movie: a massive, 150-foot-wide whirlpool had opened in the middle of the ice-choked water, violently sucking the river into the earth.
This wasn’t a natural phenomenon. It was the beginning of the Knox Mine Disaster, a catastrophic event that would not only claim lives but effectively kill the deep-mining industry in Pennsylvania forever.
The “Illegal” Dig Under the Riverbed
The disaster was born from corporate greed. Miners at the Knox Coal Company had been ordered to dig “River Slope” tunnels dangerously close to the bottom of the Susquehanna River. State law required a 50-foot “roof” of rock between the mine and the riverbed, but the company—seeking easier access to a rich coal seam—had ignored the maps.
On January 22, 1959, the roof finally gave way. The riverbed collapsed, and 10 billion gallons of icy water began thundering into the maze of tunnels below.
The “Train Car” Solution
In a desperate, frantic attempt to plug the breach, rescue teams didn’t just use sandbags—they used train cars.
Bystanders watched in disbelief as railroad cars and heavy mine equipment were pushed into the swirling vortex. The massive steel cars were reportedly sucked down into the abyss and “crushed like tin cans” by the sheer pressure of the water. In total, it took three days and dozens of cars to finally seal the hole.
The Human Cost and the “Eagle Shaft” Escape
Eighty-one miners were underground when the river broke through. While most escaped immediately, 33 men were trapped by the rising tide. In an act of incredible bravery, a miner named Amedeo Pancotti led his coworkers through a long-abandoned, 50-foot vertical air shaft to the surface, saving dozens of lives.
Tragically, 12 miners were lost. Despite massive efforts to pump out the water, their bodies were never recovered and remain entombed in the flooded depths of the mine to this day.
A Legacy Still Visible Today
The disaster triggered one of the largest grand jury investigations in the state’s history, uncovering deep-seated corruption between coal companies and union officials.
Today, the site is marked by a memorial, but for those who know where to look, a more haunting reminder remains. When the Susquehanna River level drops during a dry summer, the rusted remains of the train cars used to plug the hole can still be seen peeking out from the riverbed—a silent, metallic tombstone for the era of deep anthracite mining.
