Turns out, the Devil’s Quarry is planted 333 feet below Cardwell Mountain in Tennessee — where cavers are summoned from far and wide.
And it’s no wonder why these brave adventurers travel to make this trek. Because even though the risks involve high-ladder climbs and a gaping hole in the center of the Earth, the reward is spectacular — and magnificently rare.
Tenacious cavers on The Crucible will scale underground canyons, cross Devil’s Quarry, and climb a high winding route to The Monument Pillar — a formation known by many but witnessed by few.
