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.
