What a Tennessee Miner Found 900 Feet Underground

In the winter of 1947, Tennessee coal miner Amos Rainer descended into an abandoned shaft beneath the Cumberland Plateau carrying a carbide lamp, a hand auger, and a folded survey map that an old foreman warned him never to show anyone above ground.

Thirteen hours later, rescue crews pulled him back to the surface with blood running through his glove, streaks of white in his hair, and a story so strange that most people dismissed it as mountain superstition.

According to Amos, the deepest timber beams beneath Hollow Number Nine were older than the mine itself.

And somebody was still maintaining them.

This documentary investigates one of the strangest underground legends ever connected to the Appalachian coal fields:
forgotten shafts beneath Tennessee,
warm tunnels buried deep below documented excavation levels,
engineered black stone corridors,
withdrawn geological surveys,
and the mysterious “last beam” miners were warned never to cross.

If even part of Amos Rainer’s account was true, then something beneath the Cumberland Plateau may still exist far below the abandoned mines.

And it may still be active.
