This deeply personal collection of essays paints a progressive view of the American West as seen by a geologist. The author traces her twenty years of living and conducting research in the natural landscapes of the West as she investigates the conflict between environmental history and widely held romanticized views of the region.

Coretta Scott King - John Steptoe Award winner In this “taut, eloquent first novel” (Booklist, starred review), a young Black boy wrestles with conflicting notions of revolution and family loyalty as he becomes involved with the Black Panthers in 1968 Chicago. The Time: 1968 The Place: Chicago For thirteen-year-old Sam, it’s not easy being the son of known civil rights activist Roland Childs. Especially when his older (and best friend), Stick, begins to drift away from him for no apparent reason. And then it happens: Sam finds something that changes everything forever. Sam has always had faith in his father, but when he finds literature about the Black Panthers under Stick’s bed, he’s not sure who to believe: his father or his best friend. Suddenly, nothing feels certain anymore. Sam wants to believe that his father is right: You can effect change without using violence. But as time goes on, Sam grows weary of standing by and watching as his friends and family suffer at the hands of racism in their own community. Sam beings to explore the Panthers with Stick, but soon he’s involved in something far more serious—and more dangerous—than he could have ever predicted. Sam is faced with a difficult decision. Will he follow his father or his brother? His mind or his heart? The rock or the river?

This illustrated introduction to geology offers young readers insights into everyday signs of our constantly changing environment. Fascinating subjects include rivers of ice, the rise of volcanoes, and the formation of precious stones.

This book tells the story of water control and its impact on human history in Arizona as we understand it from Central Arizona Project archaeology.

This beautifully written and deeply personal collection of essays paints a progressive view of the American West as seen by a geologist. Ellen Wohl traces her twenty years of living and conducting research in the natural landscapes of the West as she investigates the conflict between environmental history and widely held romanticized views of the region. Wohl grew up in Ohio, subscribing to a common perception of the American West as an unchanged frontier. Moving to Arizona, she became enthralled with how the landscapes and ecosystems of the West have undergone change, both through geologic time and during the historical era of European settlement. These essays tell of her early training as a geomorphologist and provide a memorable account of her research in the rivers of the West. As the lessons accrue, Wohl gives us the benefit of her experience and shows how years of studying and living in the Colorado Rockies have enhanced her understanding of landscape change through time. Building on the literary tradition of Joseph Wood Krutch, Terry Tempest Williams, and John McPhee, Wohl provides an up-to-date portrait of the West and brings a new urgency to the call for conservation of the region's land, water, and resources.

Rivers are the great shapers of terrestrial landscapes. Very few points on Earth above sea level do not lie within a drainage basin. Even points distant from the nearest channel are likely to be influenced by that channel. Tectonic uplift raises rock thousands of meters above sea level. Precipitation falling on the uplifted terrain concentrates into channels that carry sediment downward to the oceans and influence the steepness of adjacent hill slopes by governing the rate at which the landscape incises. Rivers migrate laterally across lowlands, creating a complex topography of terraces, floodplain wetlands and channels. Subtle differences in elevation, grain size, and soil moisture across this topography control the movement of ground water and the distribution of plants and animals. Rivers in the Landscape, Second Edition, emphasizes general principles and conceptual models, as well as concrete examples of each topic drawn from the extensive literature on river process and form. The book is suitable for use as a course text or a general reference on rivers. Aimed at advanced undergraduate students, graduate students, and professionals looking for a concise summary of physical aspects of rivers, Rivers in the Landscape is designed to: emphasize the connectivity between rivers and the greater landscape by explicitly considering the interactions between rivers and tectonics, climate, biota, and human activities; provide a concise summary of the current state of knowledge for physical process and form in rivers; reflect the diversity of river environments, from mountainous, headwater channels to large, lowland, floodplain rivers and from the arctic to the tropics; reflect the diverse methods that scientists use to characterize and understand river process and form, including remote sensing, field measurements, physical experiments, and numerical simulations; reflect the increasing emphasis on quantification in fluvial geomorphology and the study of Earth surfaces in general; provide both an introduction to the classic, foundational papers on each topic, and a guide to the latest, particularly insightful and integrative references.
