An easy-to-read geological history of the amazing red rock landscapes in southeastern Utah.
Towering red buttes, plunging canyon walls, domes, pinnacles, spires, ten thousand strangely carved forms—what visitor hasn’t marveled at the land of rock in southeastern Utah that is Canyonlands Country?
Canyonlands Country offers a unique geological history of this awesome landscape, in language understandable by the non-geologist. The story is as strange and fascinating as the land itself. Each exposed rock layer has a different geologic history: one is a stream deposit, another is an ancient field of dunes, another was deposited by shallow tropic seas. The Green and Colorado Rivers began carving canyons thirty million years ago, but to understand such relatively recent events Canyonlands Country takes us on a journey of two billion years.
Tours include Arches National Park, Island in the Sky, Needles District, The Maze and Elaterite Basin, Labyrinth and Stillwater Canyons, Meander Canyon, and Cataract Canyon.
Where ancient creatures walked—science uncovers their lasting impressions.
The Steven C. Minkin (Union Chapel) Paleozoic Footprint Site ranks among the most important fossil sites in the world today, and Footprints in Stone recounts the accidental revelation of its existence and detailed findings about its fossil record.
Currently 2,500 miles from the equator and more than 250 miles north of the Gulf of Mexico, the Minkin site was a swampy tropical forest adjacent to a tidal flat during the Coal Age or Carboniferous Period more than 300 million years ago. That fecund strand of sand and mud at the ocean’s edge teemed with the earth’s earliest reptiles as well as amphibians, fish, horseshoe crabs, spiders, jumping insects, and other fascinating organisms. Unlike dinosaurs and other large animals whose sturdy bodies left hard fossil records, most of these small, soft-bodied creatures left no concrete remains. But they did leave something else. Preserved in the site’s coal beds along with insect wings and beautifully textured patterns of primeval plants are their footprints, fossilized animal tracks from which modern paleontologists can glean many valuable insights about their physical anatomies and behaviors.
The paleontological examination of fossil tracks is now the cutting-edge of contemporary scholarship, and the Minkin site is the first and largest site of its kind in eastern North America. Discovered by a local high school science teacher, the site provides both professional and amateur paleontologists around the world with a wealth of fossil track samples along with an inspirational story for amateur explorers and collectors.
Authoritative and extensively illustrated, Footprints in Stone brings together the contributions of many geologists and paleontologists who photographed, documented, and analyzed the Minkin site’s fossil trackways. An engrossing tale of its serendipitous discovery and a detailed study of its fossil records, Footprints in Stone is a landmark publication in the history of paleontology.
Northern Utah’s Wasatch Mountains are popular destinations for outdoor enthusiasts in every season. These mountains rise spectacularly from the relatively flat valley floor to thirteen peaks over 11,000 feet in elevation. An additional nineteen peaks rise more than 10,000 feet in elevation. Although many hiking guides exist for the Wasatch Mountains, there has been no guide book that focuses on the geologic features visible from the trails—until now.
Written by a recognized authority on the geology of the Wasatch Mountains, this guide is meant to enrich the experience of outdoor enthusiasts who want to understand the geological history and development of the Wasatch range. The first section of the book introduces the major geological time periods—the record of mountain building events from oldest to youngest, the effects of glaciation, and the development of the present topography. It then follows with a descriptive trail guide for each major trail system, including Mill Creek and Neffs Canyons, Mount Olympus, Little and Big Cottonwood Canyons, and Bells Canyon. Trail length, elevation gain, relative difficulty, and major geological features are outlined for each trail. Now you can hike these trails with the answers to all your geologic questions right at your fingertips.
The research in this volume derives from investigations conducted in connection with proposed widening and realignment of the Paulina-East Lake Highway, located within the caldera of Newberry Volcano. Formal evaluation of 13 localities and data recovers at four sites produced a wealth of information regarding human uses of the caldera and vicinity throughout the Holocene.
Originally published in 1882, Clarence Dutton’s Tertiary History of the Grand Cañon District has become one of the definitive books on the Grand Canyon. Commissioned as a study of the region’s geology and issued by the fledgling U.S. Geological Survey, it is as much admired today for its literary as its scientific merits. With its beautiful illustrations by Thomas Moran and William Henry Holmes, it is a seminal work on the Canyon that has never been surpassed for its eloquence and authority.
This new edition of Dutton’s magnum opus makes that work available once again. Visitors to the Canyon will gain a new appreciation of its majesty as Dutton takes readers on several excursions among its castellated and cathedral-like peaks and ridges. Along the way, he explains the peculiar characteristics of different rocks, the water-sculpturing process, volcanic cones and outflows, the extent of the river’s erosion, and other geological features.
Dutton’s Tertiary History remains arguably the most evocative and compelling geological writing ever done on the Grand Canyon region. As Stephen J. Pyne observes in his foreword, Dutton “recast a rocky peninsula into geo-poetry, reshaped an amorphous panorama of Time into narrative History, and transformed an American scene into a universal symbol.” No one who has thrilled to the majesty of the Grand Canyon will fail to be moved by this timeless work.
