“Heart-stopping and relentlessly gripping. Tabor takes us on an odyssey into unfathomable worlds beneath us, and into the hearts of rare explorers who will do anything to get there first.”—Robert Kurson, author of  ShadowDivers In 2004, two great scientist-explorers attempted to find the bottom of the world. American Bill Stone took on the vast, deadly Cheve Cave in southern Mexico. Ukrainian Alexander Klimchouk targeted Krubera, a freezing nightmare of a supercave in the war-torn former Soviet republic of Georgia.  Both men spent months almost two vertical miles deep, contending with thousand-foot drops, raging whitewater rivers, monstrous waterfalls, mile-long belly crawls, and the psychological horrors produced by weeks in absolute darkness, beyond all hope of rescue.  Based on his unprecedented access to logs and journals as well as hours of personal interviews, James Tabor has crafted a thrilling exploration of man’s timeless urge to discover—and of two extraordinary men whose pursuit of greatness led them to the heights of triumph and the depths of tragedy.  Blind Descent  is an unforgettable addition to the classic literature of true-life adventure, and a testament to human survival and endurance. “Holds the reader to his seat, containing dangers aplenty with deadly falls, killer microbes, sudden burial, asphyxiation, claustrophobia, anxiety, and hallucinations far underneath the ground in a lightless world. Using a pulse-pounding narrative, this is tense real-life adventure pitting two master cavers mirroring the cold war with very uncommonly high stakes.”— Publishers Weekly  (starred review) “A fascinating and informative introduction to the sport of cave diving, as well as a dramatic portrayal of a significant man-vs.-nature conflict. . . . What counts is Tabor’s knack for maximizing dramatic potential, while also managing to be informative and attentive to the major personalities associated with the most important cave explorations of the last two decades.”— Kirkus Reviews Includes a 16-pg black and white insert "Heart-stopping and relentlessly gripping.

Chapter One STOP. We have a fatality. BILL STONE, HALF A MILE DEEP and three miles from the entrance in a Mexican supercave called Cheve, did stop. Red-and-white plastic survey tape hung across the narrow passage he had been ascending. The message, scrawled on notebook paper, was affixed to the tape at chest level, where it could not be missed. Afloat in the cave’s absolute darkness, the white paper burned so brightly in the beam of Stone’s headlamp that it almost hurt his eyes. The time was shortly before midnight on Friday, March 1, 1991, though that made no particular difference—it was always midnight in a cave. Stone, a hard-driving man with a doctorate in structural engineering, stood six feet, four inches tall and weighed two hundred hard-muscled pounds. He was one of the leaders (two veteran cavers, Matt Oliphant and Don Coons, were the others) of an expedition trying to make the last great terrestrial discovery by proving that Cheve (pronounced CHAY-vay) was the deepest cave on earth. He had brown hair, a long hatchet face, a strong neck, intense blue eyes, and a prow of a nose angling out between them. Stone was not classically handsome, but it was a striking, unsubtle face men and women alike looked at twice. Not just n
