"The Grand Canyon is one of the most iconic tourist destinations in America and a testament to the power of nature. At its bottom, the Colorado River weaves its way through Arizona. The canyon is 277 miles long, 18 miles wide, and more than a mile deep. Native Americans have inhabited the walls of the canyon and the area around it for thousands of years, making it a location rich in human history as well as geological history. In this young reader s book, the author lays out the history of the Grand Canyon in its many facets. He includes geological and volcanic history, ecological history, human history, and its history as an attraction. By weaving these all together, the author allows the reader to better understand the mile-deep canyon weaving its way through the Southwest."--Provided by publisher.

Rivers wind through earth, cutting down and eroding the soil for millions of years, creating a cavity in the ground 277 miles long, 18 miles wide, and more than a mile deep known as the Grand Canyon. Home to an astonishing variety of plants and animals that have lived and evolved within its walls for millennia, the Grand Canyon is much more than just a hole in the ground. Follow a father and daughter as they make their way through the cavernous wonder, discovering life both present and past. Weave in and out of time as perfectly placed die cuts show you that a fossil today was a creature much long ago, perhaps in a completely different environment. Complete with a spectacular double gatefold, an intricate map and extensive back matter.

The majesty of the Grand Canyon is celebrated from the Colorado River as it continues to carve America's natural wonder from a mile below the rim. As one of the Wonders of the World and the most iconic national park in America, the Grand Canyon enthralls six million visitors each year. Only a small fraction of those people, however, have the privilege of experiencing the canyon by rafting down the Colorado River. The Grand Canyon captures and evokes the power of that journey from the drama of the rapids and the immeasurable scale of the canyon walls to the subtle rock patterns and varied life forms. What started as an exceptional opportunity for Tom Blagden to raft through The Canyon in 2006 with Rod Nash at the oars has evolved into a passionate photographic pursuit that still continues. The route--the River--is the same every time but the experience constantly variable and deeply profound. Rafters never tire of it and, if anything, feel more in awe of the Canyon's magnificence with each trip. Tom Blagden's images and Rod Nash's essay reveal the canyon from a different perspective portraying what it's like to be on the river and immersed a mile deep, surrounded by rock almost half the age of the earth. On the centennial of Grand Canyon National Park it seems only fitting that we journey together to this unique place through the pages of this astonishing book. The book weaves a wondrous adventure that will bring readers along on a journey while raising questions about the significance of a national park and an iconic American river and how to sustain them for generations to follow.

There are canyons all over the planet, and the Grand Canyon in Arizona is not the biggest. Yet because of the spectacular colors in the rock layers and fascinating formations of boulders, buttes, and mesas, it is known as one of the Seven Natural Wonders of the World. Starting with a brief overview of how national parks came into being, this book covers all aspects of the canyon--how it formed, which early native people lived there, and what varied wildlife can be found there now. A history of the canyon's end-to-end exploration in the late 1860s and how the Grand Canyon became such a popular vacation spot (5 million tourists visit every year) round out this informative, easy-to-read account.

Illustrations and simple rhyming text present a child who is hiking with a group into the Grand Canyon, enjoying the wonders of nature--whether a lizard, a picture on the stone, or a glimpse of the moon from the bottom.

Photographs made in Grand Canyon a century ago may provide us today with a sense of history; photographs made a century later from the same vantage points give us a more precise picture of change in this seemingly timeless place. Between 1889 and 1890, Robert Brewster Stanton made photographs every 1-2 miles through the river corridor for the purpose of planning a water-level railroad route and produced the largest collection of photographs of the Colorado River at one point in time. Robert Webb, a USGS hydrologist conducting research on debris flows in the Canyon, obtained the photographs and from 1989 to 1995 replicated all 445 of the views captured by Stanton, matching as closely as possible the original camera positions and lighting conditions. Grand Canyon, a Century of Change assembles the most dramatic of these paired photographs to demonstrate both the persistence of nature and the presence of humanity. Unexpected longevity of some plant species, effects of animal grazing, and expansion of cacti are all captured by the replicate photographs. More telling is evidence of the impact of Glen Canyon Dam: increased riparian vegetation, new marshes, aggraded debris fans, and eroded sand bars. In the accompanying text, Webb provides a thorough analysis of what each pair of photographs shows and places the project in its historical context. Complementing his narrative are six sidebar articles by authorities on Canyon natural history that further attest to a century of change. The level of detail obtained from the photographs represents one of the most extensive long-term monitoring efforts ever conducted in a national park; it is the most detailed documentation effort ever performed using repeat photography. Much more than simply a picture book, Grand Canyon, a Century of Change is an environmental history of the river corridor, a fascinating book that clearly shows the impact of human influence on Grand Canyon and warns us that its future is very much in our hands.
