Inundation and Emergence at Pueblo Grande de Nevada, an Eleventh-Century Ancestral Puebloan Village

ABSTRACT The development of large reservoirs in the western United States during the twentieth century inundated a diverse array of archaeological sites and other cultural resources. Land managers, cultural resource specialists, and other stakeholders have long been aware of the effects of inundation on archaeological sites, and they have sought to mitigate them by using various means at their disposal. In modern times, drought and climate change in the western United States have reduced the pool sizes of many reservoirs, including one of the largest, Lake Mead, which straddles the Arizona and Nevada border. This research presents the results of a two-year effort to study the direct and indirect effects of lacustrine-based processes at Lake Mead to a large eleventh-century prehistoric village, Pueblo Grande de Nevada. What are the processes that are most likely to damage archaeological sites and, conversely, what are those that may serve to preserve or protect them? The results of pedestrian inventory throughout the village, limited subsurface tests at certain loci, and intensive mapping at one habitation complex are used to evaluate and synthesize these effects.
