“His death became one of the most famous tragedies in American cave exploration”

Mammoth Cave is so large that even after generations of exploration, people are still discovering where it goes. Passageways stretch for hundreds of miles beneath the hills of south-central Kentucky, opening into enormous chambers, narrow crawls, underground rivers, pits, and places where complete darkness begins only a few steps beyond the lights. People have been entering these caves for thousands of years, and with that much history underground, it probably isn’t surprising that some visitors believe not everyone who entered Mammoth Cave ever completely left.

Native Americans explored the cave thousands of years before European settlers arrived in Kentucky. They traveled surprisingly deep underground using cane torches for light, mining minerals and leaving behind artifacts that remain preserved in the dry passages. European American settlers arrived in the Green River valley during the late 1700s, and by the early nineteenth century, Mammoth Cave was being mined for saltpeter used to manufacture gunpowder. Much of that dangerous work was performed by enslaved African Americans who spent long hours underground in smoke, cold, and darkness.

When saltpeter mining declined after the War of 1812, Mammoth Cave found another purpose. People wanted to see it. Tourists began arriving to explore the underground passages, and some of the people who knew those passages best were enslaved Black guides. Among them was a teenager named Stephen Bishop.

Bishop arrived at Mammoth Cave in 1838 when he was about seventeen years old. He quickly became far more than someone leading visitors along an established path. He explored portions of the cave that had never been mapped, crossed dangerous areas other people were reluctant to attempt, helped discover miles of passages, and eventually produced one of the important early maps of Mammoth Cave. Visitors wrote about him, and his knowledge of the cave became famous. He spent nearly twenty years leading people through a place where getting lost could mean never finding your way back out.

Bishop gained his freedom near the end of his life and died in 1857. He was buried in the Old Guide’s Cemetery above the Historic Entrance to Mammoth Cave, but stories eventually placed him back underground. Visitors and guides have reported seeing a shadowy male figure in the passages, sometimes described as wearing nineteenth-century clothing. Footsteps have been heard when no one appears to be walking nearby, and people have described voices, whispers, unexplained touches, and the feeling that someone is following them through the cave.

For a man who spent so much of his life guiding people through Mammoth Cave, the idea that Bishop might still be doing it became one of the cave’s most enduring ghost stories. Some visitors believe the figure they see in the darkness isn’t trying to frighten anyone at all. He’s simply still walking the passages he knew better than almost anyone alive.

But Stephen Bishop isn’t the only person whose story has become connected to the darkness beneath Mammoth Cave National Park. In 1925, a Kentucky cave explorer named Floyd Collins entered Sand Cave looking for a new cave that could be developed for tourism. This was during the Kentucky Cave Wars, when cave owners throughout the region competed for tourists and the money they brought with them. Collins had already discovered Crystal Cave in 1917 and spent years exploring the underground world around Mammoth Cave.

On January 30, Collins crawled into Sand Cave carrying a single kerosene lantern. The passage became so tight that he had to crawl on his stomach with one arm stretched ahead of him. On his way back out, his foot dislodged a twenty-seven-pound rock. It fell onto his ankle and pinned him in place about sixty feet underground. He couldn’t move forward. He couldn’t back out.

The rescue became national news. Workers dug, crawled, and eventually attempted to reach Collins by sinking a shaft from above. Crowds gathered outside Sand Cave while newspapers across the country followed what was happening underground. For more than two weeks, rescuers tried to reach him. They finally did on February 16, but Floyd Collins was already dead.

His death became one of the most famous tragedies in American cave exploration, and before long, Floyd became part of the ghost stories too. People have reported hearing unexplained voices and footsteps around places associated with Collins, and stories developed that the explorer who spent so much of his life searching for new passages was still somewhere underground.

Mammoth Cave had plenty of death associated with it even before Collins. In 1842, Dr. John Croghan established an experimental tuberculosis hospital inside the cave. At the time, tuberculosis had no reliable cure, and Croghan believed the cave’s constant temperature and air might help patients suffering from the disease. Small stone structures were built underground where desperately ill people lived inside the cave. The experiment failed, and the remains of those structures can still be seen today.

With thousands of years of human history underground, stories of strange experiences have accumulated throughout Mammoth Cave. Visitors have described cold air where there doesn’t seem to be a draft, footsteps following tour groups, voices coming from empty passages, lights appearing where no one should be standing, and the uncomfortable feeling of being watched from somewhere beyond the illuminated trail. Others have reported feeling a tap on the shoulder or a touch on the arm, only to turn around and find nobody close enough to have done it.

Some of those experiences have obvious possibilities underground. Mammoth Cave carries sound in strange ways. Air moves through passages connecting places visitors can’t see, and darkness can make distances difficult to judge. A voice from another part of the cave can travel much farther than expected.

But Mammoth Cave is also more than four hundred miles of explored darkness filled with the traces of people who came before us. Native Americans carried burning cane torches through its passages thousands of years ago. Enslaved men worked underground mining saltpeter and later guided tourists through passages they helped discover. Tuberculosis patients lived inside the cave hoping its air might save their lives. Explorers crawled into places where no one knew what waited on the other side.

Stephen Bishop spent almost twenty years walking those passages with a light in his hand, leading strangers safely through the darkness. Maybe that is why, of all the ghosts connected to Mammoth Cave, his is the one I like best.

If you’re going to meet someone in more than four hundred miles of darkness, a guide isn’t the worst person to find.
