One air tank, no lifeline, and a plunge into total darkness-read this book to experience the daring discovery that rewrote science and made survival uncertain with every breath.

Into the Absolute Darkness is the true account of Glenn Thompson's early, adventure-filled life and the events that culminated in his daring underwater exploration of Blanchard Springs Caverns. This story is about: 1) human survival in extraordinary situations that often end in tragedy, 2) the discovery of vast new underground chambers with beautiful, unique cave formations accessible only by scuba diving, and 3) scientific discoveries about the Arkansas climate during the Great Ice Age and its effect on the cavern system's development.

In the rugged Ozark Mountains of Arkansas, two Memphis State geology students set out to solve a baffling mystery: why did green dye injected where the stream disappeared inside the massive Blanchard Springs Caverns take 24 hours to emerge at Blanchard Spring, barely a mile away? Cave experts calculated it should arrive in only 3 hours. Where did the water go, and what was it doing for the other 21 hours?

Denied access to the cavern system by U.S. Forest Service officials, Glenn hatched an audacious plan: scuba dive directly into the spring and gain access to the main cavern through the uncharted watercourse. The exploration revealed extraordinary discoveries and nearly cost them their lives.

With minimal gear, a single shared air tank, and a Kodak Instamatic camera sealed inside a mayonnaise jar, Glenn and his friend Bob Langford descended into a world of total darkness where no human had ever been. Battling violent currents and inching through claustrophobic tunnels, they advanced through the labyrinth on sheer grit and instinct. Every foot forward was a victory. Every breath could have been their last.

Expecting a reprimand upon reporting their findings, they were stunned when the U.S. Forest Service recognized the magnitude of their discovery and funded further exploration. That unexpected twist launched them into a subterranean adventure that reshaped their futures-and the scientific understanding of Blanchard Springs.

Told by Glenn Thompson himself, and featuring 84 color images, this gripping true story of risk, resilience, and the thrill of discovery plunges readers into the claustrophobic darkness of the Ozarks' underground frontier, following two unlikely pioneers as they uncover secrets only the courageous dare to seek.

He received his BS in geology from the University of Rhode Island and his master's in geology from Memphis State University. While at Memphis State, Glenn and his friend Bob Langford decided to investigate the underwater cave that fed Blanchard Spring, near the town of Fifty-Six, in the Ozark Mountains of Arkansas. Their cave-diving escapade unfolded into a life-changing event that reshaped scientific knowledge about the area. His work on uranium series dating was published in Geochemica et Cosmochemica in 1975. Glenn earned his PhD at Indiana University and taught hydrogeology at the University of Arizona for seven years before founding his own company, Tracer Research Corporation. Glenn is now retired and lives in Tucson, Arizona, with his wife, Martha. Having spent several decades exploring the Sea of Cortez (Gulf of California), Glenn turned his focus to raising awareness of endangered species through his website https: //glennsphotos.com.Correa, Kimberlin: - Kimberlin Correa has been a technical and marketing communications writer since the 1990s.
