The hilltop site of Torata Alta displays a gridded site plan characteristic of Inka and Spanish colonial settlement planning, and it is now evident that the site’s brief history represents both occupations. Torata Alta began as a colony established by the Inka in the agriculturally rich Torata Valley and was settled by their Altiplano allies, the Lupaqa, in the Lake Titicaca Basin. Sometime during the early 1570s, as part of Spanish colonial administrative reforms, the community became a reducción resettlement of native Andeans drawn from small nearby hamlets. A church and ancillary buildings were constructed in the site center, and investigated structures include a beer-brewing facility and residences for textile-producing elites. In 1600, the eruption of Huaynaputina volcano and its accompanying earthquake swarm destroyed the church and covered the site with a layer of ash. Torata Alta’s residents continued living there but suffered another earthquake in 1604. The community appears to have been largely abandoned by the end of the first quarter of the seventeenth century, the residents moving down to the valley settlement that became modern Torata.

This research consists mainly of introducing the hydroarchaeological method, especially as related to issues of drought. The article outlines how this multidisciplinary method can provide insights into the success and failures of an archaeological site, in this case the Maya site of Palenque. We also detail convincing evidence that shows that the Maya of Palenque did not leave their city because of deficiencies of water, as some paleoclimatologists and archaeologists have asserted. The first logical step toward understanding any settlement’s water system is to use basic hydrologic methods and theory and to understand the local watershed. There is great potential for watershed-climate modeling in developing plausible scenarios of water use and supply and of the effect of extreme conditions (flood and drought), all of which cannot be fully represented by atmosphere-based climate and weather projections. The research demonstrates how the local watershed, land-use, and ecological conditions interact with regional climate changes. The archaeological implications for this noninvasive “virtual” method are many, including detecting periods of stress within a community, estimating population by developing caps based on the availability of water, and understanding settlement patterns, as well as assisting present local populations in understanding their water cycle.

The San Salvador River in northern Chile is a tributary of the Loa, the only river that traverses the Atacama Desert from the mountains to the Pacific. Recent investigations along the San Salvador River revealed the presence of a Formative period village site and associated cemetery approximately 110 km inland from the Pacific Ocean. Bioarchaeological and biogeochemical analyses conducted on human skeletal remains recovered from the San Salvador Cemetery allowed us to better understand the site’s role as an intermediary for coast/interior relations during the Middle Formative (500 B.C.–A.D. 100). Evidence from material culture and human remains at San Salvador suggests that this population was involved in exchange networks that united the oases of the Atacama Desert with the Pacific Ocean. Isotopic data support this notion, as the population demonstrates great variability in both the protein (marine and terrestrial) and carbohydrate components of their diet. During this period, communal economies produced surpluses used in a network of exchange for foods, prestige goods, and ideas. These ties were not coincidental but, rather, part of a regional economic structure that remains only partly explored.

Recent research and debates regarding the origin and spread of Olmec iconography during the Early Formative have centered on provenance and stylistic analyses of carved and incised pottery. Studies by instrumental neutron activation analysis (INAA) have indicated that Gulf Coast-style carved-incised pots were exported extensively from the area of the first Olmec capital, San Lorenzo, to several other regions of Mesoamerica. More recently, excavations at the Pacific Coast site of Cantón Corralito have shown that carved-incised pottery and other Olmec-style artifacts dominate strata contemporary with Early Olmec, suggesting the site may represent a settlement enclave of Gulf Olmec peoples. In this study we provide additional evidence of exchange between the Gulf Olmec and the Pacific Coast region by using laser ablation time-of-flight inductively coupled plasma mass spectrometry (LA-TOF-ICP-MS) to characterize hematite-based paints on Olmec-style pottery from Cantón Corralito, and to compare these paints to raw hematite recovered from Cantón Corralito and San Lorenzo. When examined in combination with sherd provenance data, the LA-TOF-ICP-MS data demonstrate that Olmec vessels were decorated in the San Lorenzo region before being exported to the Pacific Coast, and that Gulf Coast hematite was exported to Cantón Corralito, where it was used to enhance Olmec-style symbolism on locally produced vessels.

The Cave of Hun Nal Ye, located in central Guatemala, was discovered unlooted by a local landowner in 2005 and was immediately subject to investigation by the authors. The cave contained ritual remains dating to between the Terminal Pre-classic and Terminal Classic. In addition to allowing a detailed reconstruction of ritual activity in the northern highlands, its presence along the Great Western Trade Route allows archaeologists to examine hypotheses about interregional trade during the Classic period. In particular, changes in the ritual assemblage between the Early and Late Classic indicate that the cave was an important trade shrine for merchants and travelers passing between the highlands and lowlands until ca. A.D. 550, at which point it became a local shrine used to reinforce elite power. These changes are then linked to larger patterns occurring in other parts of the trade route, especially to Tikal and the kingdoms along the Pasión and Usumacinta rivers.
