This book in two volumes is the culmination of over twenty-five years of conjecture. Why didn't archaeologist Stuart Baldwin, PhD (1946-1999) fully write up his research after a decade of work on the now extinct Piro-Tompiro culture in Central New Mexico? Why didn't he return to the Southwest after 1988? What happened to the artifacts and notes from five years of excavation by a University of Calgary, Alberta, Canada, field school at Tenabo Pueblo, a large fourteenth to seventeenth century pueblo? The answers to these questions, and a treasure trove of physical evidence and years of scholarship were discovered in 2016. This included detailed reports on the archaeology, ethnohistory and history of the Abo Pass region of New Mexico, along with complete site analyses of numerous surveys and limited excavations carried out in the region. Although completed nearly thirty years ago, Baldwin's work remains the single most comprehensive and accurate presentation on the Native American Pueblo culture in Central New Mexico. In these volumes we tell the story of rediscovering Baldwin's life work and present all of a nearly 1,400 page unpublished manuscript that remained hidden for years in a research library's archives. This is the second of these volumes and deals with archaeology and prehistory including rock art. Volume I is focused on history and ethnology. As Baldwin wrote in the preface of his "lost" manuscript: "I believe (in) any attempt to pull together and present available information on (a)...cultur(e)..., even if it is 'only' the morality of saving a people from historical obscurity."
