Grand Canyon is one of Earth's most recognizable landscapes. Though scientists have studied the canyon for more than 150 years, a definitive answer as to how and when the canyon formed eludes them. The one thing they do agree on is that the canyon was carved by the erosive power of the Colorado river, but the river itself carried away the evidence of its earlier history. Carving Grand Canyon examines the many intriguing ideas and innovative theories that geologists have developed over time about the formation of the canyon. In the last seven years since the publication of the first edition of Carving Grand Canyon, new theories have been brought forth, and this second edition of the book captures these fresh ideas and examines them in the light of other theories. This story of a fascinating landscape is told in an engaging style that is inviting to casual readers interested in the mystery of Grand Canyon's formation.
This concise and comprehensive text explains all the Grand Canyon essentials. With its wide range of topics, readers pick and choose what to read and learn: geology, including the main theories about the canyon’s process of creation, natural and human history, an abstract of the John Wesley Powell saga, a description of South Rim trails, and details about the canyon’s dimensions and varying ecozones from rim to river. Presented in three parts, the text is written in a forthright manner, whose literary style avoids extraneous details and embellished writing. Thus, The Everything Grand Canyon Book provides readers with a factual account, whose subject matter aligns with an interpretative account of subject matter, and not just a description. (Note: the standard book format page-count is 53 pages, while the ePublishing format may be 2 or 3 times as high.)
A nearly 1,000-page literary tour of 85 scenic icons based on an interpretive account of national parks, monuments, state parks, and archeological ruins. Focus on geology, human and natural history. Where applicable, additional matter is introduced (i.e., hiking trails, archeoastronomy, and desert ecology). Presented in the guise of an encyclopedia the text can be read from cover-to-cover or piecemeal. Reader decides which destinations to select. Information is layered from easy and essential to the more detailed. Reader also decides what to peruse. Additional Background inserts suffice as footnotes; therefore optional text. Contact information and directions also listed. Bitly URL’s embedded in destinations activate Google images, graphics, charts and illustrations. There are six addenda of subject matter relative to the scope of the text; also, bibliography.
This traveler's guidebook takes the reader on a virtual sightseeing and educational jaunt along the Grand Canyon’s South Rim. Thus, conveying all aspects of the canyon: geology, natural and human history, including six addenda on relevant subject matter (i.e., facts about the Colorado Plateau, things to do and see in Grand Canyon Village, and a lexicon of geologic terms. Using the South Rim's interpretive walking timeline trail as a means to disseminate information to the reader, this factual and informative text presents common details in an uncommon way. Specifically, a demotic writing style that changes the academics of geoscience, natural and human history into a casual parlance employed by educator-guides addressing clients, students and friends. Along The Trail Of Time, therefore, feigns its own tour, only in a literary sense, while explaining details without sermonizing. Standard book format: 193 pages
John Wesley Powell's Perilous Journey and His Vision for the American West
Author: John F. Ross
A timely, thrilling account of a man who, as an explorer, dared to lead the first successful expedition down the Colorado through the Grand Canyon--and, as an American visionary, waged a bitterly-contested campaign for environmental sustainability in the American West. When John Wesley Powell became the first person to navigate the entire Colorado River, through the Grand Canyon, he completed what Lewis and Clark had begun nearly 70 years earlier--the final exploration of continental America. The son of an abolitionist preacher, a Civil War hero (who lost an arm at Shiloh), and a passionate naturalist and geologist, in 1869 Powell tackled the vast and dangerous gorge carved by the Colorado River and known today (thanks to Powell) as the Grand Canyon. With The Promise of the Grand Canyon, John Ross recreates Powell's expedition in all its glory and terror, but his second (unheralded) career as a scientist, bureaucrat, and land-management pioneer concerns us today. Powell was the first to ask: how should the development of the west be shaped? How much could the land support? What was the role of the government and private industry in all of this? He began a national conversation about sustainable development when most everyone else still looked upon land as an inexhaustible resource. Though he supported irrigation and dams, his prescient warnings forecast the 1930s dustbowl and the growing water scarcities of today. Practical, yet visionary, Powell didn't have all the answers, but was first to ask the right questions.
A look into the life and passion of David D. Rust (1874-1963), a pioneer in adventurous backcountry guided tours of the Colorado Plateau province of Utah and Arizona, who led month-long pack trips through a mind-boggling variety of cliffs, mesas, mountaintop overlooks, and hidden desert canyons.
