More than ten thousand known caves lie beneath the state of Tennessee according to the Tennessee Cave Survey, a nonprofit organization that catalogs and maps them. Thousands more riddle surrounding states. In Hidden Nature, Michael Ray Taylor tells the story of this vast underground wilderness. In addition to describing the sheer physical majesty of the region’s wild caverns and the concurrent joys and dangers of exploring them, he examines their rich natural history and scientific import, their relationship to clean water and a healthy surface environment, and their uncertain future.
As a longtime caver and the author of three popular books related to caving—Cave Passages, Dark Life, and Caves—Taylor enjoys (for a journalist) unusual access to this secretive world. He is personally acquainted with many of the region’s most accomplished cave explorers and scientists, and they in turn are familiar with his popular writing on caves in books; in magazines such as Audubon, Outside, and Sports Illustrated; and on websites such as those of the Discovery Channel and the PBS science series Nova.
Hidden Nature is structured as a comprehensive work of well-researched fact that reads like a personal narrative of the author’s long attraction to these caves and the people who dare enter their hidden chambers.

“Michael Ray Taylor’s Hidden Nature is destined to become to wild Southern caves what Bill Bryson’s A Walk in the Woods is to the Appalachian Trail: a book that reaches both beginners and experts, the merely curious and the passionately obsessed alike. Moving elegantly between personal experience, history, and science, it brings to vibrant life a secret world full of marvels and mysteries and, above all, beauty.”~Margaret Renkl
—Margaret Renkl, author of Late Migrations: A Natural History of Love and Loss
“Welcome to a whole new world you will not want to come up from. Thank goodness Michael Taylor has the writing chops to describe it all beautifully, and exactly, and with the suspense and tension necessary to any great read.”~Clyde Edgerton
—Clyde Edgerton, author of The Night Train and Papadaddy’s Book for New Fathers
“Part detective story, part memoir, part geological history—Michael Ray Taylor’s beautiful Hidden Nature is an unputdownable book. I expected bats and stalactites, sure—but his lifelong love and obsession dropped me beneath the earth I know, fascinated. For cavers and non-cavers, this is a must read, I promise.”~George Singleton
—George Singleton, author of You Want More: Selected Stories
“This captivating and insightful book captures the essence of American caving and speleology, from the author’s beginnings as a caver, to science, prominent explorers, the Golden Age of Cave Discovery, and more—lots more. I think it gives the best explanation yet of ‘the why.’”~Bill Steele
—Bill Steele, author of Yochib: The River Cave
“A riveting account of caves and the unique individuals who explore them. With one action-filled adventure after another, the reader learns not only about caves but also much about the human spirit and the hearts and minds of cavers—some of the most dedicated and eclectic of explorers.”~Chris Nicola

Several long caves reach this valley. I'm digging with hopes of breaking into a new one from a short, allegedly dead-end passage. The surrounding landscape is karst, a term derived from a German word describing the geology and topography of the Dinaric Alps, now applied to any limestone landscape featuring caves, sinkholes, and streams that vanish underground. I was sweating before I began this work because I could not find the entrance, hiking an unnecessary hour through boulders, chest-high thorns, and cow pies before giving up, driving up to the ridge for a cell signal, and calling the landowner for more detailed directions. Then I drove straight to it, thorns scratching at my rented SUV, boulders and stobs threatening to gouge the pan. I geared up and crawled over the rough cobbles of the entrance to begin digging in a smooth-walled rotunda at the end of the known space.
Barely two hundred feet long, this little cave has been known to local residents for over a century. Proof is written on the white limestone ceiling in the form of a half-dozen blackened signatures and dates, scrawled in candle smoke by rural visitors during the late 1800s and early 1900s. Elsewhere in this valley are caves explored by much earlier settlers from early in the nineteenth century all the way back to Native Americans who lit their way with cane torches thousands of years ago.
People have always been drawn underground. The oldest human remains have been discovered in the caves of Africa, Europe, and Asia-some of them older than our most ancient common ancestor. A spate of studies of human mitochondrial DNA has pushed forward the date when a small band of African humans began to populate the rest of the world. As recently as sixty thousand years ago, or fewer than two thousand human generations, our common ancestors may have journeyed outward. Traces of their lives persist: caves serve as repositories for the earliest known examples of art, basketry, shoes, and clothing.
Humanity's more recent spread through the American South is also chronicled below ground. Less than an hour's drive away from the spot where I lie digging, I once followed bare footprints in soft, damp cave mud, noting bits of ash and mineral samples dropped by three walkers. Protected from casual obliteration by colored plastic flagging and extreme secrecy, these prints were made by the lined, leathered feet of explorers who traversed the passage more than four thousand years before me, according to the carbon dating of bits of river cane that fell from their flickering torches.
A big-eared bat chirps nearby. Ruffling leathery wings with a drumming sound, he objects to my intrusion into his normally silent chamber. Over the past decade much of the bat population of the eastern United States has been decimated by white-nose syndrome, a deadly plague spread by fungal spores, but the few individuals I can see appear robust and healthy. Their annual hibernation period will soon approach. For now the weather outside remains warm enough that I know they will exit at sunset, each consuming hundreds of insects before returning at dawn.
Except for bats and a few cave crickets, I'm alone in a passage perhaps twenty feet wide and twelve feet high at the center. The old signatures are spread over a comfortable alcove where the ceiling height is about six feet. Farther from the center of the chamber, the roof slopes downward to meet the floor, giving the room the appearance of a lens. At the edge where I've worked for the past hour, the white limestone ceiling sits no more than twenty inches above the dried mud on which I recline. I reach with a garden hoe into a still smaller space, barely wider than the hoe's blade: the spot where all present-day drainage vanishes. Water is rare here. The entrance sits on the high side of a sinkhole so that it only comes in during the largest floods.
Following a list of clues over the past few months, I have found reason to believe that somewhere beyond the reach of my hoe unexplored passages and chambers await, perhaps connecting to a hidden borehole winding southward from the plateau. I can't say that I'm here merely in the hope of scientific discovery. Other cavers far more accomplished than me have also been poking into sinks in this area, seeking a back door into a known subterranean system many miles long. I deeply admire these explorers: I once wrote a glowing profile of their cantankerous patriarch, Marion O. Smith, in Sports Illustrated, a publication not normally known for caver stories. Smith is by far the world's most experienced caver, with well-documented trips to over eight thousand separate caves in his seventy-seven years. Each of these caves is meticulous documented in a shelf of journals going back over sixty years, yet he calls the "most experienced" title "hogwash."
