Abstract

This interdisciplinary thesis presents results from field and laboratory investigations of archaeological sites in a ~150-km coast-highland corridor in southern Peru, aimed at better understanding the Terminal Pleistocene biogeographic expansion of humans into the high-altitude Andes and possible early coast-highland links. I integrated a number of approaches to understand late-glacial landscapes and to locate early hunter- gatherer archaeological sites, including creation of a digital database of archaeological radiocarbon data, geochemical characterization of the Alca obsidian source, quantitative geographic information systems (GIS) predictive modeling, region-level archaeological survey, geophysical surveys, test excavations, and systematic surface collections, and accelerator mass spectrometry (AMS) dating of the Cuncaicha rockshelter (4488 m elevation), the highest Pleistocene archaeological site yet discovered in the world. This interdisciplinary work in the high Peruvian Andes has yielded evidence that despite colder temperatures, more extensive glaciers, and low-oxygen conditions, successful human colonization of high-altitude environments began ~12,400-12,000 years ago at the end of the last ice age.
