Color photos of the Escalante and the Paria river canyons and the adjacent plateau into which these rivers, with the help of rain & wind, have sculpted surreal, brightly colored galleries. The text by Charles Bowden deals with Mormon heroes, the Hole-in-the-Rock migration, and with John D. Lee, infamous for his part in the Mountain Meadows Massacre.

An overview of the Colorado Plateau's fossil remains of organisms that lived millions of years ago, featuring numerous illustrations and photographs.

* Expanded to include Grand Staircase/Escalante, Vermilion Cliffs, Canyons of the Ancients, Dinosaur, and Hovenweep National Monuments * Color photo insert * Many sights accessible by car From the sheer-walled magnificence of Zion to the breathtaking intricacy of Bryce Canyon's sculptured turrets; from the "Grand Staircase" of the Vermilion Cliffs, and Pink Cliffs in southern Utah to the volcanic lavas of Sunset Crater: two geologists describe the star attractions of 24 national parks and monuments. New sidebars provide closer looks at specific details such as the large numbers of dinosaur footprints in and around Arches National Park and geology's profound effect on ancient Pueblo peoples and how they lived. Geologist Halka Chronic is the author of several books on geology. Geologist Lucy Chronic has served as a park interpreter at Bandelier National Monument in Los Alamos, New Mexico. Grand Staircase, Escalante, Vermilion Cliffs, Canyons of the Ancients, Dinosaur, Hovenweep National Monuments, Zion, Bryce Canyon, Grand Staircase of the Vermilion Cliffs, Pink Cliffs in southern Utah, volcanic lavas of Sunset Crater, geologists, dinosaur footprints in and around Arches National Park

Written with the general reader in mind, this is the updated edition of the classic on the geology of the red rock and canyon country of the Fours Corners region of Utah, Colorado, Arizona, and New Mexico.

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

Sunrise illuminates Colorado Plateau’s canyon country. In the early morning light, cliffs radiate a rich red glow, and a sculptured panorama of sandstone is revealed in a rich palette of crimson, vermilion, orange, salmon, peach, pink, gold, yellow, and white. Nearby are black, spherical rock marbles (iron concretions) collecting in small depressions, like puddles of ball bearings. These natural spherical balls have been called various names such as iron nodules, iron sandstone balls, or moki marbles. However, we use the name “iron concretion” to describe both the composition (iron oxide that is the dark mineral which cements the sandstone grains) and the formed shape (concretion). What paints the sandstone such rich colors? Why is red a dominant color? Where do the black marbles come from? How did the black marbles form? Is there a relationship between sandstone colors and the marbles? This booklet explores the answers to these questions and poses other questions yet unanswered.
