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.

The Pulitzer Prize-winning view of the continent, across the fortieth parallel and down through 4.6 billion years 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.

Todos somos habitantes de la Tierra, pero muchos desconocemos los procesos que modifican y a veces sacuden su superficie.Este libro es una completa introducción a la naturaleza y la historia de la Tierra: trata de los volcanes y de los fosiles, de los problemas de vivir bajo la amenaza de un terremoto y de las limitaciones de los recursos naturales.Con la ayuda de fotografias a color y dibujos ilustrativos explica, de manera clara y amena:- el origen y la evolucion de la Tierra,- los tipos de rocas, minerales y fosiles,- los procesos geologicos clave para nuestro planeta,- los terremotos y volcanes,- la geologia de otros planetas,- como realizar un trabajo de campo.
