Drawing on scholarly research and archaeological evidence, the author examines the accomplishments of the Anasazi people of the American Southwest and speculates on why the culture vanished by the 13th century.

    Lakes are changing rapidly, not because we are separate from nature but because we are so much a part of it. While many of our effects on the natural world today are new, from climate change to nuclear fallout, our connections to it are ancient, as core samples from lake beds reveal. In Still Waters, Curt Stager introduces us to the secret worlds hidden beneath the surfaces of our most remarkable lakes, leading us on a journey from the pristine waters of the Adirondack Mountains to the wilds of Siberia, from Thoreau’s cherished pond to the Sea of Galilee.Through decades of firsthand investigations, Stager examines the significance of our impacts on some of the world’s most iconic inland waters. Along the way he discovers the stories these lakes contain about us, including our loftiest philosophical ambitions and our deepest myths. For him, lakes are not only mirrors reflecting our place in the natural world but also windows into our history, culture, and the primal connections we share with all life.Beautifully observed and eloquently written, Stager’s narrative is filled with strange and enchanting details about these submerged worlds—diving insects chirping underwater like crickets, African crater lakes that explode, and the growing threats to some of our most precious bodies of water. Modern science has demonstrated that humanity is an integral part of nature on this planet, so intertwined with it that we have also become an increasingly powerful force of nature in our own right. Still Waters reminds us how beautiful, complex, and vulnerable our lakes are, and how, more than ever, it is essential to protect them.

     Where do clouds come from? Why do they look the way they do? And why have they captured the imagination of timeless artists, Romantic poets, and every kid who's ever held a crayon? Journalist and lifelong sky watcher Gavin Pretor-Pinney reveals everything there is to know about clouds, from history and science to art and pop culture. Cumulus, nimbostratus, and the dramatic and seemingly surfable Morning Glory cloud are just a few of the varieties explored in this smart, witty, and eclectic tour through the skies. Generously illustrated with striking photographs and line drawings featuring everything from classical paintings to lava lamps, children's drawings, and Roman coins, The Cloudspotter's Guide will have science and history buffs, weather watchers, and the just plain curious floating on cloud nine.

    A bold foray into the heart of the American West’s final frontier, the expedition was achieved without benefit of modern river-running equipment, supplies, or a firm sense of the region’s perilous topography and the attitudes of the native inhabitants towards whites.For more than seventy years, Penguin has been the leading publisher of classic literature in the English-speaking world.

    The news is full of archaeology: treasures found (British king under parking lot) and treasures lost (looters, bulldozers, natural disaster, and war). Archaeological research tantalizes us with possibilities (are modern humans really part Neandertal?). Where are the archaeologists behind these stories? What kind of work do they actually do, and why does it matter?Marilyn Johnson’s Lives in Ruins is an absorbing and entertaining look at the lives of contemporary archaeologists as they sweat under the sun for clues to the puzzle of our past. Johnson digs and drinks alongside archaeologists, chases them through the Mediterranean, the Caribbean, and even Machu Picchu, and excavates their lives. Her subjects share stories we rarely read in history books, about slaves and Ice Age hunters, ordinary soldiers of the American Revolution, children of the first century, Chinese woman warriors, sunken fleets, mummies.What drives these archaeologists is not the money (meager) or the jobs (scarce) or the working conditions (dangerous), but their passion for the stories that would otherwise be buried and lost.

    Deliberately hiding from the outside world, they are the unconquered, the last survivors of an ancient culture that predates the arrival of Columbus in the New World.  In this gripping first-person account of adventure and survival, author Scott Wallace chronicles an expedition into the Amazon’s uncharted depths, discovering the rainforest’s secrets while moving ever closer to a possible encounter with one such tribe—the mysterious flecheiros, or “People of the Arrow,” seldom-glimpsed warriors known to repulse all intruders with showers of deadly arrows. On assignment for National Geographic, Wallace joins Brazilian explorer Sydney Possuelo at the head of a thirty-four-man team that ventures deep into the unknown in search of the tribe. Possuelo’s mission is to protect the Arrow People. But the information he needs to do so can only be gleaned by entering a world of permanent twilight beneath the forest canopy.Danger lurks at every step as the expedition seeks out the Arrow People even while trying to avoid them. Along the way, Wallace uncovers clues as to who the Arrow People might be, how they have managed to endure as one of the last unconquered tribes, and why so much about them must remain shrouded in mystery if they are to survive. Laced with lessons from anthropology and the Amazon’s own convulsed history, and boasting a Conradian cast of unforgettable characters—all driven by a passion to preserve the wild, but also wracked by fear, suspicion, and the desperate need to make it home alive—The Unconquered reveals this critical battleground in the fight to save the planet as it has rarely been seen, wrapped in a page-turning tale of adventure.

    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.

    But what are the rules for facing a moose up close? Do you run from a coyote or curl up and play dead? How deadly, really, are black widow spiders, rattlesnakes, and jellyfish? Packed with expert tips, fascinating animal facts, and harrowing true tales, Look Big is a must-have survival guide for hikers, campers, and owners of skunk-sprayed suburban pets everywhere.

    But how many of us get to make a living at it, spending days observing nature from the canopies of stunning forests all around the world? As a wildlife cameraman for the BBC and National Geographic, James Aldred spends his working life high up in trees, poised to capture key moments in the lives of wild animals and birds. Aldred’s climbs take him to the most incredible and majestic trees in existence. In Borneo, home to the tallest tropical rain forest on the planet, just getting a rope up into the 250-foot-tall trees is a challenge. In Venezuela, even body armor isn’t guaranteed protection against the razor-sharp talons of a nesting Harpy Eagle. In Australia, the peace of being lulled to sleep in a hammock twenty-five stories above the ground— after a grueling day of climbing and filming—is broken by a midnight storm that threatens to topple the tree.   In this vivid account of memorable trees he has climbed (“Goliath,” “Apollo,” “Roaring Meg”), Aldred blends incredible stories of his adventures in the branches with a fascination for the majesty of trees to show us the joy of rising—literally—above the daily grind, up into the canopy of the forest.

    Olson explores the haunting appeal of the wilderness.

    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.
