Radiocarbon Data from Middle Horizon Sites in the Upper Majes Valley, Arequipa Peru

In 2019, fifteen AMS radiocarbon dates were obtained across four Middle Horizon (AD 600-1000) sites located in the upper Majes Valley in Arequipa, Peru. These include Wari contexts from the sites Pakaytambo and El Tambo, and local road waystations of Santa Rosa II and La Angostura. Dating of both construction and abandonment contexts indicate these sites correspond to the late Middle Horizon, a time of intense connectivity in the prehistoric Andes and Wari state expansionism. This data is a component of the PhD dissertation entitled <em>Networks of Empire: The Role of Infrastructure in Wari State Expansion in Arequipa, Peru (AD 600-1000)</em> by David A. Reid (University of Illinois at Chicago). Funding was provided by the National Science Foundation’s Doctoral Dissertation Research Improvement Award (#1854651).
