    His destination was nearly 900 feet below the surface. On January 8th he descended into the water. About fifteen feet below the surface was a fissure in the bottom of the basin, barely wide enough to admit him. He slipped through the opening and disappeared from sight, leaving behind the world of light and life. Then, a second diver descended through the same crack in the stone. This was Don Shirley, Shaw's friend, and one of the few people in the world qualified to follow where Shaw was about to go. In the community of extreme diving, Don Shirley was a master among masters.Twenty-five minutes later, one of the men was dead. The other was in mortal peril, and would spend the next 10 hours struggling to survive, existing literally from breath to breath. What happened that day is the stuff of nightmarish drama, but it’s also a compelling human story of friendship, heroism, ambition, and of coming to terms with loss and tragedy.

    He set records, he developed the techniques, and he maintained the highest standards of excellence.Sheck lived a life of adventure, danger, and excitement of a degree that few people can ever dream of, or, if they do, those dreams are nightmares. Cave diving is the world's most dangerous sport. If you participate on the highest level, you know that some of your best friends are going to die. If you continue to push yourself and your equipment to the limits--if you persist in being a world class diver as Sheck was--the chances are very high that you, too, will die.This book may terrify you, but it will unquestionably fascinate you, and in the end, Sheck Exley will convince you that his death came to him in the midst of the incredibly intense joy he took in diving into the depths of the earth.

    In 1969 we even walked on the moon. And yet as late as 2000, the earth’s deepest cave—the supercave—remained undiscovered. This is the story of the men and women who risked everything to find it, earning their place in history beside the likes of Peary, Amundsen, Hillary, and Armstrong. In 2004, two great scientist-explorers are attempting to find the bottom of the world. Bold, heroic American Bill Stone is committed to the vast Cheve Cave, located in southern Mexico and deadly even by supercave standards. On the other side of the globe, legendary Ukrainian explorer Alexander Klimchouk—Stone’s polar opposite in temperament and style, but every bit his equal in scientific expertise, physical bravery, and sheer determination—has targeted Krubera, a freezing nightmare of a supercave in the Republic of Georgia, where underground dangers are compounded by the horrors of separatist war in this former Soviet republic.

    Blehm narrates this true account of the disappearance and search for Randy Morgenson, a National Park Service ranger who, one morning after 28 seasons on the job, failed to answer his radio call.The introverted Morgenson was more comfortable with the natural world than with people. A gifted photographer and a lyrical writer, he dropped out of college to begin a career that would send him into the remote parts of California's Sequoia and Kings Canyon National Parks. Passionate about the mountains, he excelled at his responsibilities, which ranged from clearing away garbage left by careless campers to rescuing injured hikers. Dedicated to keeping the wilderness undisturbed, he was proud of his ability to leave no trace of himself wherever he camped.That skill would prove costly when, at age 54, he went missing. Blehm seamlessly combines a detective story with a celebration of nature that calls to mind the works of classic American writers like Thoreau and Emerson. His gripping narrative will cause readers' hearts to ache at the disappearance of this undervalued soul. But their spirits will soar at the grandeur and mysticism of nature expertly captured in its most primal state.

    Gabrielle Walker, author, consultant to New Scientist and regular broadcaster with the BBC has written a book unlike any that has ever been written about the continent. Antarctica weaves all the significant threads into an intricate tapestry, made up of science, natural history, poetry, epic history, what it feels like to be there and why it draws so many different kinds of people back there again and again. It is only when all the parts come together that the underlying truths of the continent emerge. Antarctica is the most alien place on Earth, the only part of our planet where humans could never survive unaided. It is truly like walking on another planet. And yet, in its silence, its agelessness and its mysteries lie the secrets of our past, and of our future.

    A week later, Lincoln Hall, a seasoned Australian climber, was left for dead near the same spot. Hall's death was reported around the world, but the next day he was found alive after spending the night on the upper mountain with no food and no shelter.If David Sharp's death was shocking, it was hardly singular: despite unusually good weather, ten others died attempting to reach the summit that year. In this meticulous inquiry into what went wrong, Nick Heil tells the full story of the deadliest year on Everest since the infamous season of 1996. He introduces Russell Brice, the commercial operator who has done more than anyone to provide access to the summit via the mountain's north side—and who some believe was partly accountable for Sharp's death. As more climbers attempt the summit each year, Heil shows how increasingly risky expeditions and unscrupulous outfitters threaten to turn Everest into a deadly circus.Written by an experienced climber and outdoor writer, Dark Summit is both a riveting account of a notorious climbing season and a troubling investigation into whether the pursuit of the ultimate mountaineering prize has spiraled out of control.

    This man was a freediver, and his amphibious abilities inspired Nestor to seek out the secrets of this little-known discipline. In Deep, Nestor embeds with a gang of extreme athletes and renegade researchers who are transforming not only our knowledge of the planet and its creatures, but also our understanding of the human body and mind. Along the way, he takes us from the surface to the Atlantic’s greatest depths, some 28,000 feet below sea level. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and seals who dive to depths below 2,400 feet for up to eighty minutes—deeper and longer than scientists ever thought possible. As strange as these phenomena are, they are reflections of our own species’ remarkable, and often hidden, potential—including echolocation, directional sense, and the profound physiological changes we undergo when underwater. Most illuminating of all, Nestor unlocks his own freediving skills as he communes with the pioneers who are expanding our definition of what is possible in the natural world, and in ourselves.

    From one of the top cave divers working today—and one of the very few women in her field—Into the Planet blends science, adventure, and memoir to bring readers face-to-face with the terror and beauty of earth’s remaining unknowns and the extremes of human capability.Jill Heinerth—the first person in history to dive deep into an Antarctic iceberg and leader of a team that discovered the ancient watery remains of Mayan civilizations—has descended farther into the inner depths of our planet than any other woman. She takes us into the harrowing split-second decisions that determine whether a diver makes it back to safety, the prejudices that prevent women from pursuing careers underwater, and her endeavor to recover a fallen friend’s body from the confines of a cave. But there’s beauty beyond the danger of diving, and while Heinerth swims beneath our feet in the lifeblood of our planet, she works with biologists discovering new species, physicists tracking climate change, and hydrogeologists examining our finite freshwater reserves. Written with hair-raising intensity, Into the Planet is the first book to deliver an intimate account of cave diving, transporting readers deep into inner space, where fear must be reconciled and a mission’s success balances between knowing one’s limits and pushing the envelope of human endurance.

    From the moment the Andrea Doria settled on the sea floor in 240 feet of water, skilled sport divers have risked their lives to simply touch the "Mount Everest of wreck diving." Not all returned alive. Peter Hunt crewed on five Andrea Doria expeditions during the early 1980s before becoming a Navy pilot and settling in Washington State. Nearly twenty years after first exploring the Andrea Doria - and following twelve months of training in the sport's amazing advances in equipment and techniques - Hunt hugged his wife and children goodbye and returned to New York to dive the Andrea Doria once again. The experience transformed him forever. Setting the Hook explores the Andrea Doria through an introspective odyssey of memory, heart-pounding adventure, and history as thirty years of extreme diving and enduring friendships merge in a personal tale of learning to accept life's oldest challenge.

    Testing themselves against treacherous currents, braving depths that induced hallucinatory effects, navigating through wreckage as perilous as a minefield, they pushed themselves to their limits and beyond, brushing against death more than once in the rusting hulks of sunken ships.But in the fall of 1991, not even these courageous divers were prepared for what they found 230 feet below the surface, in the frigid Atlantic waters sixty miles off the coast of New Jersey: a World War II German U-boat, its ruined interior a macabre wasteland of twisted metal, tangled wires, and human bones–all buried under decades of accumulated sediment.No identifying marks were visible on the submarine or the few artifacts brought to the surface. No historian, expert, or government had a clue as to which U-boat the men had found. In fact, the official records all agreed that there simply could not be a sunken U-boat and crew at that location.Over the next six years, an elite team of divers embarked on a quest to solve the mystery. Some of them would not live to see its end. Chatterton and Kohler, at first bitter rivals, would be drawn into a friendship that deepened to an almost mystical sense of brotherhood with each other and with the drowned U-boat sailors–former enemies of their country. As the men’s marriages frayed under the pressure of a shared obsession, their dives grew more daring, and each realized that he was hunting more than the identities of a lost U-boat and its nameless crew.Author Robert Kurson’s account of this quest is at once thrilling and emotionally complex, and it is written with a vivid sense of what divers actually experience when they meet the dangers of the ocean’s underworld. The story of Shadow Divers often seems too amazing to be true, but it all happened, two hundred thirty feet down, in the deep blue sea.

    Everest disaster vanished into thin air, one man had the courage to bring them down alive... On May 10, 1996, two commercial expeditions headed by expert leaders attempted to scale the world's largest peak. But things went terribly wrong. Crowded conditions, bad judgement, and a bitter storm stopped many climbers in their tracks. Others were left for dead, or stranded on the frigid mountain. Anatoli Boukreev, head climbing guide for the Mountain Madness expedition, stepped into the heart of the storm and brought three of his clients down alive. Here is his amazing story-of an expedition fated for disaster, of the blind ambition that drives people to attempt such dangerous ventures, and of a modern-day hero, who risked his own life to save others..

    He’s been bitten by twenty-six venomous snakes, been stung by three stingrays, and survived a near-fatal scorpion sting while deep in the Amazon jungle. He’s received more than four hundred stitches and broken twenty-three bones, including breaking his back in three places, and had to learn how to walk again. But when you research only the venom you yourself have collected, the adventures—and danger—never stop.Imagine a three-week-long first date in Siberia catching venomous water shrews with the daughter of a Russian war hero; a wedding attended by Eastern European prime ministers and their machine-gun-wielding bodyguards and snakes; or leading a team to Antarctica that results in the discovery of four new species of venomous octopi. Bryan’s discoveries have radically reshaped views on venom evolution and contributed to the creation of venom-based life-saving medications. In pursuit of venom, he has traveled the world collecting samples from Indonesia to Mexico, Germany, and Brazil. He’s encountered venomous creatures of all kinds, including the Malaysian king cobra, the Komodo dragon, and the brush-footed trapdoor spider. Bryan recounts his lifelong passion for studying the world’s most venomous creatures in this outlandish, captivating memoir, where he and danger are never far apart.

    In this engrossing narrative of the Far North, enriched by her own adventurous sojourns in the Arctic, Andrea Pitzer brings Barents' three harrowing expeditions to vivid life--while giving us fascinating insights into one of history's most intrepid navigators.

    Sir Douglas Mawson is remembered as the young Australian who would not go to the South Pole with Robert Scott in 1911, choosing instead to lead his own expedition on the less glamorous mission of charting nearly 1,500 miles of Antarctic coastline and claiming its resources for the British Crown. His party of three set out through the mountains across glaciers in 60-mile-per-hour winds. Six weeks and 320 miles out, one man fell into a crevasse, along with the tent, most of the equipment, all of the dogs' food, and all except a week's supply of the men's provisions.Mawson's Will is the unforgettable story of one man's ingenious practicality and unbreakable spirit and how he continued his meticulous scientific observations even in the face of death. When the expedition was over, Mawson had added more territory to the Antarctic map than anyone else of his time. Thanks to Bickel's moving account, Mawson can be remembered for the vision and dedication that make him one of the world's great explorers.
