The Ramaditas archaeological site in the Atacama Desert of northern Chile provides evidence for cultural adaptations during wetter environmental conditions in an otherwise arid environment. From 2.0 – 2.5 kyr B.P., regional population increased and a cultural shift toward agricultural based communities occurred. Tree samples collected from the site provide a high-resolution record of increased water availability as recorded by tree ring oxygen and carbon isotopes. Prosopis tamarugo logs from...

This is an abstract from the "Archaeology, Cultural Heritage, and Public Education at Tijeras Pueblo, New Mexico" session, at the 84th annual meeting of the Society for American Archaeology. This paper describes how Linda Cordell, working with colleagues, including me, used building timbers to (1) date room construction and village occupation at Tijeras Pueblo, (2) understand villager’s choices about wood use, (3) describe changing climate conditions associated with the village’s occupation,...

The Middle to Later Stone Age transition in East Africa ~30-60 ka has been hypothesized as a response to increased resource risk due to cooler, drier Late Pleistocene environments with greater short-term variability. Local paleoenvironmental records are needed to test such hypotheses. Ostrich eggshell (OES) fragments are common in African archaeological sequences, are amenable to 14C and U-series dating, and their δ13C and δ15N values are known to correspond to the C isotopes of vegetation and...

Payson Sheets’ seminal work on the Tierra Joven Blanca (TBJ) eruption of the Ilopango Caldera, El Salvador was one of the first projects to address the impact of large-scale disasters in Mesoamerica. The on-going research on this eruption has been important for understanding the event as well as developing method and theory for reconstructing the cultural impact(s) of sudden massive stresses. While originally dated to AD 290±110, the TBJ eruption has been re-dated to the mid 5-6th century and...

This is an abstract from the "Fryxell Symposium in Honor of Dolores Piperno" session, at the 88th annual meeting of the Society for American Archaeology. Dolores Piperno has been a trailblazer in interdisciplinary research, building on deep, innovative approaches to plant remains to answer a multitude of questions in archaeology and beyond. In this interdisciplinary spirit, I review research into Holocene paleoclimate along the Peruvian coast derived in the first instance from the study of...
