x, 210 pages : 25 cm, \"Sparsely settled mountain areas of the world, such as Colorado's Front Range, give an impression of wild, untouched, and unchanging nature. Yet in many cases mountain rivers that appear to be pristine natural systems actually have been impaired as a result of human activities. In this book, Ellen Wohl documents two hundred years of land-use patterns on the Front Range and their wide-ranging effects on river ecosystems.\" \"This book fills an important gap with a clear and comprehensive explanation of how rivers are changed by human activity. The book also includes a generous selection of striking historical and contemporary photographs, maps, and diagrams that provide a fresh perspective on the extent to which the rivers of the Colorado Front Range have undergone change during the last two centuries.\"--Jacket, Includes bibliographical references (pages 181-207)
