Gathers current research on the understudied late mobile groups of the American Southwest and provides directions for future investigations Trending upward as an archaeological field of study, protohistoric mobile groups provide fascinating new directions for cutting-edge research in the American Southwest and beyond. These mobile residents represent the ancient and ancestral roots of many modern indigenous peoples, including the Apaches, Jumano, Yavapai, and Ute. These important protohistoric and historic mobile people have tended to be ignored because their archaeological sites were deemed too difficult to identify, too scant to be worthy of study, and too different to incorporate. This book brings together information from a diverse collection of authors working throughout the American Southwest and its fringes to make the bold statement that these groups can be identified in the archaeological record and their sites have much to contribute to the study of cultural process, method and theory, and past lifeways. The period is much more complex than previously thought and requires the application of innovative and keen approaches, as discussed in this volume. Mobile groups are integral for assessing the grand reorganizational events of the Late Prehistoric period and are key to understanding colonial contact and transformations. Now, the only analyses, overviews, and class lectures that will be considered comprehensive will be those that address the presence of these many widespread mobile peoples.
