Allow yourself to be taken back into deep geologic time when strange creatures roamed the Earth and Western North America looked completely unlike the modern landscape. Volcanic islands stretched from Mexico to Alaska, most of the Pacific Rim didn’t exist yet, at least not as widespread dry land; terranes drifted from across the Pacific to dock on Western Americas’ shores creating mountains and more volcanic activity. Landscapes were transposed north or south by thousands of kilometers along huge fault systems. Follow these events through paleogeographic maps that look like satellite views of ancient Earth. Accompanying text takes the reader into the science behind these maps and the geologic history that they portray. The maps and text unfold the complex geologic history of the region as never seen before. Winner of the 2021 John D. Haun Landmark Publication Award, AAPG-Rocky Mountain Section

Imagine seeing the varied landscapes of the earth as they used to look throughout hundreds of millions of years of earth history. Tropical seas lap on the shores of an Arizona beach. Immense sand dunes shift and swirl in Sahara-like deserts in Utah and New Mexico. Ancient rivers spill from a mountain range in Colorado that was a precursor to the modern Rockies. Such flights of geologic fancy are now tangible through the thought-provoking and beautiful paleogeographic maps, reminiscent of the maps in world atlases we all paged through as children, of Ancient Landscapes of the Colorado Plateau.Ron Blakey of Northern Arizona University is one of the world's foremost authorities on the geologic history of the Colorado Plateau. For more than fifteen years, he has meticulously created maps that show how numerous past landscapes gave rise to the region's stunning geologic formations. Ancient Landscapes of the Colorado Plateau is the first book to showcase Blakey's remarkable work. His maps are accompanied by text by Wayne Ranney, geologist and award-winning author of Carving Grand Canyon. Ranney takes readers on a fascinating tour of the many landscapes depicted in the maps, and Blakey and Ranney's fruitful collaboration brings the past alive like never before.Features: More than 70 state-of-the-art paleogeographic maps of the region and of the world, developed over many years of geologic research Detailed yet accessible text that covers the geology of the plateau in a way nongeologists can appreciate More than 100 full-color photographs, diagrams, and illustrations A detailed guide of where to go to see the spectacular rocks of the region

The incredible story of the creation of a continent—our continent— from the acclaimed author of The Last Volcano and Mask of the Sun. 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, John Dvorak's How the Mountains Grew will fill readers with a newfound appreciation for the wonders of the land we live on.

This 2004 book provides a concise, accessible account of the geology and landscape of Southwest USA, for students and amateurs.

This textbook explains how mountains are formed and why there are old and young mountains. It provides a reconstruction of the Earths paleogeography and shows why the shapes of South America and Africa fit so well together. Furthermore, it explains why the Pacific is surrounded by a ring of volcanos and earthquake-prone areas while the edges of the Atlantic are relatively peaceful. This thoroughly revised textbook edition addresses all these questions and more through the presentation and explanation of the geodynamic processes upon which the theory of continental drift is based and which have led to the concept of plate tectonics. It is a source of information for students of geology, geophysics, geography, geosciences in general, general natural sciences, as well as professionals, and interested layman.

Carving Grand Canyon provides a synopsis of the intriguing ideas and innovative theories that geologists have developed over time. This story of a fascinating landscape is told in an engaging style that nonscientists will find inviting. The story's end, however, remains a mystery yet to be solved.

This volume, aimed at the general reader, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies. Grazing, predation, and multi-tiered ecosystems with animals living in, on, or above the sea floor became common. The cascade of interaction led to an ever-increasing diversification of animal body types. By the end of the period, the ancestors of sponges, corals, jellyfish, worms, mollusks, brachiopods, arthropods, echinoderms, and vertebrates were all in place. The evidence of this Cambrian "explosion" is preserved in rocks all over the world, including North America, where the seemingly strange animals of the period are preserved in exquisite detail in deposits such as the Burgess Shale in British Columbia. Cambrian Ocean World tells the story of what is, for us, the most important period in our planet's long history.
