In the Mimbres Valley of southwestern New Mexico, archaeologists have been working for decades to meticulously excavate archaeological sites. Expanding beyond studies that focus on a single pueblo, this volume represents the final report on the excavations of the Mimbres Foundation. It brings together data from a range of pithouse and pueblo sites of different sizes and histories in diverse locations—to refine the current understandings of Mimbres region archaeology in the context of the Greater Southwest. From the end of the Late Pithouse period through the Black Mountain phase, the book provides excellent documentation of the artifacts and data recovered from the sites, addresses models of Mimbres community, and tracks change and continuity in the valley over centuries. In addition, the authors consider the nature of the relationship between the Classic Mimbres period population of the valley and the people of the succeeding Black Mountain phase, as well as relationships among the Black Mountain phase people and those of neighboring parts of the region, including the Casas Grandes world and the Jornada Mogollon area. In Ancient Communities in the Mimbres Valley two leading archaeologists bring together a trove of unpublished investigations, expanding understandings and setting a course for the future.
