2016 Southwest Symposium Poster. Recent work in the Upper Gila River Valley of Arizona documents two Early Agricultural period cerros de trincheras and a riverine residential site. This presentation summarizes recent field work and addresses issues related to chronology, the role of agriculture, and warfare. Early Agricultural period cerros de trincheras have been previously documented in the Río Casas Grandes and in the Tucson Basin. The Upper Gila River Valley sites expand this phenomenon to a...

Abstract: Zuni Salt Lake, a maar in the Red Hill–Quemado volcanic field in New Mexico, holds great significance in the oral traditions of a handful of tribes including the Zuni and Hopi. We redefined the age of volcanic eruptions at Zuni Salt Lake using radiocarbon and optically stimulated luminescence dating. Four radiocarbon ages on wood charcoal indicate two main eruptive phases: a violent strombolian eruption at ~13.3 ka and a later, predominantly...

As the emphasis on preservation archaeology increases, the application of non-destructive technologies to artifact analysis is becoming more relevant and commonplace. We employ three such techniques, decorrelation stretch (DStretch), x-ray fluorescence (XRF), and Fourier-transform Raman spectroscopy (FT-Raman), to investigate multiple paint hues found on a single pre-Classic Hohokam Red-on-buff sherd. We apply DStretch to visually enhance the paint and confirm the presence of two red hues. The...

The pottery tradition is a hallmark of the Salado Phenomenon, and its analysis has been applied to many questions, including those concerned with technology, exchange, identity, religion, and migration. The black paint on Roosevelt...
