That tantalizing swirl of dye confirmed speculations that were to tempt more than 650 cavers over half a century with the thrill of being the first to make human passage of the cave connection. Roger Brucker and Richard Watson tell not only of their own twenty-year effort to complete the link but the stories of many others who worked their way through mud-choked crawlways less than a foot high only to find impenetrable blockages.
Floyd Collins died a grisly death in nearby Sand Cave in 1925, after being trapped there for 15 days. The wide press coverage of the rescue efforts stirred the imagination of the public and his body was on macabre display in a glass-topped coffin in Crystal Cave into the 1940s. Agents of a rival cave owner once even stole his corpse, which was recovered and still is in a coffin in the cave. Modern cavers still have a word with Floyd as they start their downward treks.
Brucker and Watson joined the parade of cavers who propelled themselves by wiggling kneecaps, elbows, and toes through quarter-mile long crawlways, clinging by fingertips and boot toes across mud-slick walls, over bottomless pits, into gurgling streams beneath stone ceilings that descend to water level, down crumbling crevices and up mountainous rockfalls, into wondrous domed halls, and straight ahead into a blackness intensified rather than dispelled by the carbide lamps on their helmets.
Over two decades they explored the passages with others who sought the final connection as vigorously as themselves. Pat Crowther, a young mother of two, joined them and because of her thinness became the member of the crew to go first into places no human had ever gone before. In that role, in July 1972, she wiggled her way through the Tight Spot and found the route that would link the Flint Ridge and Mammoth Cave systems into one cave extending 144.4 miles through the Kentucky limestone.
In a new afterword to this edition the authors summarize the subsequent explorations that have more than doubled the established length of the cave system. Based upon geological evidence, the authors predict that new discoveries will add another 200 miles to the length of the world’ s longest cave, making it over 500 miles long.
This P.S. edition features an extra 16 pages of insights into the book, including author interviews, recommended reading, and more.

Uranium is a common element in the earth's crust and the only naturally occurring mineral with the power to end all life on the planet. After World War II, it reshaped the global order-whoever could master uranium could master the world.
Marie Curie gave us hope that uranium would be a miracle panacea, but the Manhattan Project gave us reason to believe that civilization would end with apocalypse. Slave labor camps in Africa and Eastern Europe were built around mine shafts and America would knowingly send more than six hundred uranium miners to their graves in the name of national security.
Fortunes have been made from this yellow dirt; massive energy grids have been run from it. Fear of it panicked the American people into supporting a questionable war with Iraq and its specter threatens to create another conflict in Iran. Now, some are hoping it can help avoid a global warming catastrophe.
In Uranium, Tom Zoellner takes readers around the globe in this intriguing look at the mineral that can sustain life or destroy it.

The book deals with the practical and theoretical sides of gemmology. Tracing the background and science of gemmology, the book covers the gem material, geological formation, and occurrence of gemstones on the earth. The composition of gemstones from the atoms, elements, molecules, and compounds comprising them is analyzed, and the relationship between chemical composition and durability of the stone is explained. The basics of crystallography is mentioned as a tool toward understanding gemmology after which cleavage, parting, and fracture are done. A gemstone's durability and hardness and how the latter influences engineering tests and the mining techniques are compared. An important test technique to identify unmounted stones is the measure of specific gravity using displacement measurement methods and hydrostatic methods. After more descriptive details are given in identification of gemstones, whether these are synthetic or simulants, through a comprehensive explanation of the materials found in these other gemstones, the fashioning, through shaping or polishing, of gemstones is explained. Emphasis is given on the critical angle in which light rays pass in different rock densities, and then the cutting styles, gemstone polishing, and grading are discussed.
Students studying for the Gemmological Association's Preliminary and Diploma examinations, jewelers, lapidarists, and diamond cutters, as well as those engaged in the hobby of gemmology, will find this book helpful and full of information toward their endeavors and hobbies.

Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it might have been dark matter that killed the dinosaurs.
Working through the background and consequences of this proposal, Randall shares with us the latest findings—established and speculative—regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos’ history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things.
Twenty years ago, when John McPhee began his journeys back and forth across the United States, he planned to describe a cross section of North America at about the fortieth parallel and, in the process, come to an understanding not only of the science but of the style of the geologists he traveled with. The structure of the book never changed, but its breadth caused him to complete it in stages, under the overall title Annals of the Former World.
Like the terrain it covers, Annals of the Former World tells a multilayered tale, and the reader may choose one of many paths through it. As clearly and succinctly written as it is profoundly informed, this is our finest popular survey of geology and a masterpiece of modern nonfiction.
Annals of the Former World is the winner of the 1999 Pulitzer Prize for Nonfiction.
Interweaving physics, astronomy, chemistry, geology, and biology, this sweeping account tells Earth’s complete story, from the synthesis of chemical elements in stars, to the formation of the Solar System, to the evolution of a habitable climate on Earth, to the origin of life and humankind. The book also addresses the search for other habitable worlds in the Milky Way and contemplates whether Earth will remain habitable as our influence on global climate grows. It concludes by considering the ways in which humankind can sustain Earth’s habitability and perhaps even participate in further planetary evolution.
Like no other book, How to Build a Habitable Planet provides an understanding of Earth in its broadest context, as well as a greater appreciation of its possibly rare ability to sustain life over geologic time.

With the same intense curiosity and narrative flair she displayed in her widely-praised book Color, Finlay journeys from the underground opal churches of outback Australia to the once pearl-rich rivers of Scotland; from the peridot mines on an Apache reservation in Arizona to the remote ruby mines in the mountains of northern Burma. She risks confronting scorpions to crawl through Cleopatra’s long-deserted emerald mines, tries her hand at gem cutting in the dusty Sri Lankan city where Marco Polo bartered for sapphires, and investigates a rumor that fifty years ago most of the world’s amber was mined by prisoners in a Soviet gulag.
Jewels is a unique and often exhilarating voyage through history, across cultures, deep into the earth’s mantle, and up to the glittering heights of fame, power, and wealth. From the fabled curse of the Hope Diamond, to the disturbing truths about how pearls are cultured, to the peasants who were once executed for carrying amber to the centuries-old quest by magicians and scientists to make a perfect diamond, Jewels tells dazzling stories with a wonderment and brilliance truly worthy of its subjects.
