S. Department of the Interior, Office of Water Research and Technology Grant No. 14 -31- 0001 -5254, to the University of Arizona, Office of Arid Lands Studies, Patricia Paylore, Principal Investigator. [Two other Papers, Nos. 5 and 7 in the series, were funded by another Federal agency.] Arid Lands Resource Information Paper No. 2, "Exploration and Exploitation of Geothermal Resources in Arid and Semiarid Lands," first issued in 1973, is now out -of- print. The intent of the present Paper was to revise that earlier literature review with its annotated bibliography, by recognizing the unusual developments in this field in the interim, with new geothermal fields dis- covered, new demands for geothermal energy as an alternative source to more conventional sources, and an astonishing number of new publications reflecting accelerated research. As the knowledgeable reader of this new Paper will sense, however, the author has gone far beyond a simple update by offering us an innovative and we believe a completely new position from which to view this exotic energy source and contemporary efforts to develop it.To many of us, the young are ordinarily looked upon as reckless and extremist, but this is not the first time I have found the young looking beyond today, or even tomorrow, to think critically and soberly about long- term effects instead of short -term benefits.Duffield, native Tucsonan, with a Master's degree in geology and now pursuing the Ph.D. degree in Arid Lands Resource Sciences, is such a person. Like his predecessors in this series: Casey (No. 1, 1972), Sherbrooke (No. 3, 1973), Chalmers (No. 4, 1974), and Bowden (No. 6, 1975), Duffield has been bold to challenge conventional technical wisdom, but I do not think I have been foolhardy to support him and those others.I believe this is the purpose of education - to experiment, create, disagree, learn, and provoke, within a frame- work of severe discipline.This Paper satisfies me that it too is a worthy example of such attitudes. I wish once more to thank the National Science Foundation for its early funding of the development of the computer program which now handles so successfully the Arid Lands Information System (ALIS ). The extensive bibliography accompanying this Paper was produced by ALIS, and includes over one hundred references prepared by the Office of Arid Lands Studies originally under previous OWRT/ WRSIC grants. These, and others where users are referred to SWRA [ Selected Water Resources Abstracts ]in lieu of abstracts, are taken from RECON, ERDA's Oak Ridge -based information system. While Duffield and I are grateful to OWRT /WRSIC for their support of the Office of Arid Lands Studies, University of Arizona, in helping maintain this Office as a U.S. Center of Competence in water -related problems of arid lands, neither the U. S. Department of the Interior nor the University of Arizona is responsible for the views expressed herein. Patricia Paylore Assistant Director Office of Arid Lands Studies The University of Arizona November 22, 1976 PREFACE Why have you opened this book? If you are attracted by one of the key concepts in the title (geothermal, technoecosystems, water cycles, arid lands) then there is something here for you.This is an ambitious and multifaceted work designed for a very diverse audience, yet in its structure it is a unified whole.Naturally, I hope that you will have time and broad enough interest to read the entire text and appreciate its overall scheme. But I realize that for some readers only one or two sections will be especially pertinent and useful.Therefore, to help guide you to the most relevant sections, I will briefly outline the book's goals and underlying organization. My aim has been to comprehensively review the literature on geothermal resources and the technology for exploiting them, with particular attention to arid lands and the various roles of water. But more than that, I have tried to develop a single holistic intellectual framework within which all this diverse detailed technical information can be rationally and intuitively and esthetically synthesized, and within which any future geothermal discoveries and activities can be easily comprehended. The new framework I have come up with, what I call "technoecology ", is based on the close analogy between biological ecosystems and large complex industrial systems ( "technoecosystems "), and may actually transcend in importance and universal applicability the geothermal review which it structures. The book has three major divisions: the first chapter, the rest of the text, and the bibliography.Chapter I presents, for the first time in print, the basic structure and major insights of technoecology at its present embryonic stage of development. Subsequent chapters apply technoecological methods and language in an extensive overview of geothermal topics. Those who are interested only in technoecology need read just the first chapter; however, they will miss a concrete application and extension of its principles. Geothermal purists can start reading at Chapter II, but they may find them- selves bewildered by unfamiliar terminology and concepts.Clearly, these two parts of the book comple- ment and enhance each other. The 300 -item annotated bibliography not only supports the text and its literature citations, but should also be useful in itself -- its computerized indexes offer rapid access to the geothermal literature. Here are a few highlights of the geothermal review: Chapter II traces geothermal heat back to its astrophysical origins billions of years ago. And geological details of natural geothermal reservoirs are organized by a new unifying concept of hierarchically cascaded convection

Includes bibliographical references and index. 1. Close air support--History--20th century. 2. United States. Air Force--History--20th century. 3. United States. Army--Aviation--History--20th century. I. Title. UG703.S35 2003 358.4'142--dc22 2003020365 ii Foreword The issue of close air support by the United States Air Force in sup- port of, primarily, the United States Army has been fractious for years. Air commanders have clashed continually with ground leaders over the proper use of aircraft in the support of ground operations. This is perhaps not surprising given the very different outlooks of the two services on what constitutes prop- er air support. Often this has turned into a competition between the two serv- ices for resources to execute and control close air support operations. Although such differences extend well back to the initial use of the airplane as a military weapon, in this book the author looks at the period 1946- 1973, a period in which technological advances in the form of jet aircraft, weapons, communications, and other electronic equipment played significant roles. Doctrine, too, evolved and this very important subject is discussed in detail. Close air support remains a critical mission today and the lessons of yesterday should not be ignored. This book makes a notable contribution in seeing that it is not ignored.

  • USGS Scientific Investigations Map 2832, Pamphlet
    Geologic Map of Mount Mazama and Crater Lake Caldera, Oregon By Charles R. Bacon Pamphlet to accompany Scientific Investigations Map 2832 View from the south-southwest rim of Crater Lake caldera showing the caldera wall from Hillman Peak on the west to Cleetwood Cove on the north. Crater Lake fills half of the 8- by 10-km-diameter caldera formed during the climactic eruption of Mount Mazama volcano approximately 7,700 years ago. Volcanic rocks exposed in the caldera walls and on the flanks record over 400,000 years of eruptive history. The exposed cinder cone and andesite lava flows on Wizard Island represent only 2 percent of the total volume of postcaldera volcanic rock that is largely covered by Crater Lake. Beyond Wizard Island, the great cliff of Llao Rock, rhyodacite lava emplaced 100–200 years before the caldera-forming eruption, dominates the northwest caldera wall where andesite lava flows at the lakeshore are approximately 150,000 years old. 2008 U.S. Department of the Interior U.S. Geological Survey This page intentionally left blank.
