Excerpt from The Climatic Factor as Illustrated in Arid America The lines of reasoning followed thus far are similar to those which I have employed in respect to various countries of Asia, and which were first set forth in a volume entitled Exploration in Turkestan, published by the Carnegie Institution of Washington in 1905, and have been amplified and revised in The Pulse of Asia and Palestine and its Trans formation, published ih 1907 and 1911, respectively. The conclusions derived from these lines of reasoning are open to the criticism that a preconceived theory may have led to the interpretation of phenomena according to that theory. Hence, before the conclusions here indicated deserve final acceptance, it is necessary to compare them with the results Obtained by the observations of other unprejudiced workers, or with the independent results of some new method in which the personal equation plays no part. Fortunately the work of Professor A. E. Douglass, of the University of Arizona, suggests a method by which old trees may be used as a mathematical measuring-rod in order to determine exactly what climatic events have occurred during the last or years. Accord ingly, considerable space will be devoted to setting forth the results of the measurement of the rate of growth of nearly 500 Sequoia trees among the Sierra Mountains in California. A large number of other measurements of trees by the United States Forest Service have been kindly put at the disposal of the Carnegie Institution of Washington by the Forester, Mr. Henry S. Graves, and a discussion of them is included in this volume. By purely mathematical methods, unaffected by any personal bias, it has been possible to obtain curves indicating the climatic pulsations of the last years. A comparison of these curves with the results obtained from other lines of evidence, both in America and Asia, shows that in spite of certain disagreements the general climatic history of both continents appears to have been characterized by similar pulsations having a periodicity of hundreds or thousands of years.

Stretching from the four corners of Arizona, New Mexico, Colorado, and Utah, the Colorado Plateau is a natural laboratory for a wide range of studies. This volume presents 23 original articles drawn from more than 100 research projects presented at the Sixth Biennial Conference of Research on the Colorado Plateau. This scientific gathering revolved around research, inventory, and monitoring of lands in the region. The book's contents cover management techniques for cultural, biological, and physical resources, representing collaborative efforts among federal, university, and private sector scientists and land managers. Chapters on cultural concerns cover benchmarks of modern southwestern anthropological knowledge, models of past human activity and impact of modern visitation at newly established national monuments, challenges in implementing the 1964 Wilderness Act, and opportunities for increased federal research on Native American lands. The section on biological resources comprises sixteen chapters, with coverage that ranges from mammalian biogeography to responses of elk at the urban-wildland interface. Additional biological studies include the effects of fire and grazing on vegetation; research on bald eagles at Grand Canyon and tracking wild turkeys using radio collars; and management of palentological resources. Two final chapters on physical resources consider a proposed rerouting of the Rio de Flag River in urban Flagstaff, Arizona, and an examination of past climate patterns over the Plateau, using stream flow records and tree ring data. In light of similarities in habitat and climate across the Colorado Plateau, techniques useful to particular management units have been found to be applicable in many locations. This volume highlights an abundance of research that will prove useful for all of those working in the region, as well as for others seeking comparative studies that integrate research into land management actions.

Deadly Landscapes presents a series of cases that advance the rigorous examination of war in the archaeological record. The studies encompass examples from the Hohokam, Sinagua, Mogollon, and Anasazi regions, plus a pan-regional study of iconography covering the Colorado Plateau and the Rio Grande Valley. All of the cases focus on the narrow time frame from AD 1200 to the early-1400s, during which evidence for warfare is most pervasive. Contributors to this volume present varying definitions of warfare and use differing types of data to test for the presence of warfare. These detailed case studies give clear demonstration of a pattern of significant warfare in the late prehistoric period that will alter our understanding of ancient Southwestern cultures.
