Pegasus Books How the Mountains Grew: A New Geological History of North America
The incredible story of the creation of a continent—our continent— from the acclaimed author of The Last Volcano and Mask of the Sun."Exuberant. Dvorak is a wonderful storyteller [and] challenges the conventional wisdom. This will enrich your everyday personal experiences.”—The Wall Street Journal The immense scale of geologic time is difficult to comprehend. Our lives—and the entirety of human history—are mere nanoseconds on this timescale. Yet we hugely influenced by the land we live on. From shales and fossil fuels, from lake beds to soil composition, from elevation to fault lines, what could be more relevant that the history of the ground beneath our feet?For most of modern history, geologists could say little more about why mountains grew than the obvious: there were forces acting inside the Earth that caused mountains to rise. But what were those forces? And why did they act in some places of the planet and not at others? When the theory of plate tectonics was proposed, our concept of how the Earth worked experienced a momentous shift. As the Andes continue to rise, the Atlantic Ocean steadily widens, and Honolulu creeps ever closer to Tokyo, this seemingly imperceptible creep of the Earth is revealed in the landscape all around us. But tectonics cannot—and do not—explain everything about the wonders of the North American landscape. What about the Black Hills? Or the walls of chalk that stand amongst the rolling hills of west Kansas? Or the fact that the states of Washington and Oregon are slowly rotating clockwise, and there a diamond mine in Arizona?It all points to the geologic secrets hidden inside the 2-billion-year-old-continental masses. A whopping ten times older than the rocky floors of the ocean, continents hold the clues to the long history of our planet.With a sprightly narrative that vividly brings this science to life, this revised edition of John Dvorak's monumental How the Mountains Grew will fill readers with a newfound appreciation for the wonders of the land we live on.

What do Emily Dickinson, slave revolts, Babylonian Kings, and Monticello all have in common? A solar eclipse. Whether it was deciding on the location of a grand home (or castle), inspiring poetry, timing battles and revolts, or planning expeditions, eclipses have inspired fear and fascination. Solar eclipses allowed Ptolemy to determine the length of the Mediterranean and helped Einstein establish his General Theory of Relativity. Preliterate societies recorded eclipses on turtle shells found in The Wastes of Yin and on the Mayan Dresden Codex. Eclipses were later instrumental in the creation of longitude and allowed Hubble to understand the expansion of the Universe (and disprove another theory of Einstein''s in the process). John Dvorak, the acclaimed author of Earthquake Storms and The Last Volcano, examines this amazing phenomena and reveals the humanism behind the science. With insightful detail and vividly accessible prose, he provides explanations as to how and why eclipses occu
