The procurement of high-quality lithic resources is amongst the most indicative processes of decision-making in the archaeology of early human groups peopling the Americas. Directly dated deposits from quarry workshops have been absent of the late Pleistocene record of South America. We present the results of the excavations of a high-quality translucent quartz crystal workshop that yielded radiocarbon-dated coherently layered stratigraphic deposits that shed light into the behavior of the initial stages of lithic procurement. Based on a detailed analysis of the context of the Valiente site (32˚S, Chile, South America), we discuss the stages of bifacial production of point technology. The deposit produced evidence of cumulative occupations over the period between 12,630 and 11,320 calibrated years before present. This ~1,300-year span is coincidental with a major environmental step-wise drying trend as indicated by the local and regional pollen records. Furthermore, it is synchronous to the process in which natural landscapes became the earliest taskscapes in the region, thereby encompassing major cultural changes related to the organization of the land use. These results are discussed in the frame of contemporaneous archaeological data to discuss specific aspects of technology and decision-making of the earliest settlers of South America.

Central Western Patagonia (CWP) is a key area for assessing long-distance procurement of high-quality obsidians throughout the Holocene given that almost all relevant types represented in the archaeological record are exotic to this region. By using surface and stratigraphic obsidian artifacts from archaeological sites compared to standards from known sources in Patagonia, this paper discusses the spatial and
temporal distribution of this lithic material. Sampling was oriented to assemblages from deposits with radiocarbon-based time frames (10,700-300 cal BP). This paper presents geochemical (ICP-MS) analyses of 178 samples from 58 archaeological sites at 11 surveyed areas located along the Pacific coast, the Andean forest, and eastern steppe. Out of six potential sources, the Chaiten Volcano source (Los Lagos Region, Chile) dominates exclusively the occurrence of obsidians along the coastal fringe, while the Pampa del Asador source (PDA, Santa Cruz Province, Argentina) largely dominates (86% of samples) obsidian in the eastern steppe and the forest/steppe ecotone. This broad distribution is explained by the presence of the densely forested Andean mountain range acting as a biogeographical barrier. East of the Andes, we recorded an absolute dominance of PDA south of 45 30S, while more variability prevailed north of this point. The highest diversity of obsidians was recorded in the Cisnes River valley, probably because it is located closer to other alternative northern sources (Telsen/Sierra Negra, Sacanana and Angostura Blanca, all in Chubut Province, Argentina) and because it also hosts a local low-quality obsidian type. Based on this distribution, we discuss obsidian procurement behaviors by considering obsidian frequency and tool/debitage-class representation with increasing distance. We use the analysis of fall-off curves based on the distance of studied locations from the sources and include the use of leastcost paths for providing the most likely procurement routes. No obsidian diversification was recorded during the Holocene, hence the main driver for its procurement seems to be the distance from the source rather than the antiquity of its knowledge. Alternative procurement behaviors are discussed, specifically direct acquisition, exchange, and/or sporadic visits as mechanisms for explaining the archaeological patterns throughout the Holocene .

En este trabajo se presentan y discuten características del registro arqueofaunístico de dos
sitios ubicados en la meseta del Strobel ocupados durante el siglo XX por grupos familiares de ascendencia indígena: Puesto Yatel y Puesto Quintillán. Dado su carácter marginal para la ganadería, la meseta del Strobel fue ocupada en su totalidad tardíamente por las estancias ganaderas, siendo hasta entonces un lugar de “refugio” para familias de ascendencia indígena que optaron por no incorporarse al sistema de reservas indígenas vigentes. Inmersos en un contexto de creciente arrinconamiento y pérdida de tierras, dichos grupos familiares adoptaron nuevas estrategias económicas. Con el propósito de conocer en mayor profundidad estos cambios se presenta el análisis del material arqueofaunístico, centrado en los perfiles de representación de partes esqueletarias, la composición taxonómica de los conjuntos y los perfiles de edad. Asimismo se discute dicha información con la proveniente del análisis de la tecnología vítrea, lítica y arquitectónica de los sitios y las fuentes históricas. De este modo, se analiza el rol que tuvo la economía pastoril, el comercio y la caza en las estrategias desarrolladas por los ocupantes de los sitios y cómo estas se transformaron a lo largo del siglo XX.

The forest-steppe ecotone of the eastern slope of the Andes in Central Western Patagonia (43° 40 ′ –49° 15 ′ S, Chile, South America) provides a unique area for assessing long and short term dynamics between humans and past environments. Central Western Patagonia was a demographically marginal zone inhabited intermittently and with low intensity by hunter-gatherers during the Holocene. This paper adopts a novel approach in order to assess the relationship between trends in the archeological, pollen, and charcoal records. The recognition of temporal and spatial scales in both archeology and paleoecology is crucial for defining roles in paleofire records. The main goal of the paper is to assess the role of climate and human beings as potential ignitors of wildfires by acknowledging the scales in which they operate and the different roles either one played in paleofire trends. We investigated a case study in the Cisnes River Valley (CRV) where the frequencies and magnitudes of fire episodes—reconstructed from macro-charcoal particles from the Lake Shaman intermoraine sequence—can be attributed to human action, while acknowledging the driving role of climate over broader time scales. The Lake Shaman charcoal record spanning the last 19,000 cal years is compared to the archeological record starting at 11,500 cal years BP. After comparing paleofires, reconstructed from the charcoal record, with peaks and troughs in the radiocarbon record and archeological evidence at local and site scales, we argue that this approach provides insights for assessing the timing and magnitude of human effects on the environment. We examine collation and correlation scenarios for comparative trends between the archeological, pollen, and charcoal records. The correlation of occupational events at the El Chueco 1 archeological site and other sites along the CRV with the results obtained at Lake Shaman is suggestive of a combination of human agency and climate drivers in the occurrence of fires during most of the Holocene.

This work aims to build a comprehensive isotopic ecology with the ultimate purpose of assessing long-term human diet decision-making by means of stable isotope analysis. We present a set of δ13Ccollagen and δ15Ncollagen isotopic values on the main faunal resources from the forest and steppe areas of the Aisén región (Central-Western Patagonia, Chile), in order to characterise their isotopic ranges and assess their consumption by past hunter–gatherer populations. Two sets of bioarchaeological remains are used for this comparison; a 10 200–9700 cal year BP assemblage from Baño Nuevo cave and a 1600–300 cal year BP assemblage gathered at different locations throughout Aisén. Isotopic signals from both assemblages indicate diets based on the consumption of protein provided by terrestrial mammals from steppe environments and no long-term signature of forest-resource consumption. On the other hand, the earlier group shows values that may indicate a wider dietary breadth, although this observation is preliminary. These results further suggest that the use of forests and the resources they provided, although visible through the zooarchaeological record (i.e. taxa represented at sites), must have been discontinuous and, perhaps, marginal in comparison with steppe regions.

This article discusses the distribution of radiocarbon age signatures obtained from archeological sites between 29° and 35° S in Central Chile and Midwest Argentina. The goal of this analysis is to establish bases from which to interpret regional trends in the distribution of the archaeological record that connect these areas, which have been traditionally considered to be geographically decoupled. We propose a standardized methodology for selecting ages that provide a reliable human signature. Variations in date frequencies in a regional scale are discussed with the use of summed probability distributions. Radiocarbon voids at the regional level previously identified in Midwest Argentina are explored. Regional chronological information is compared to the available paleoenvironmental records, thereby emphasizing the possible role of climate pulses in the spatial organization of human populations. Significant arid conditions between 7800 and 5700 cal BP are coincidental with a focused occupation of the Andes Mountains, area which may have offered stable resources; thus more effectively occupied when compared to other environmental bands.
Keywords: radiocarbon dates; climate change; human paleoecology; hunter-gatherers; mid-Holocene; Subtropical Andes.

"During the 19th century, stockbreeding in Argentinean Patagonia
started to advance over the area occupied by the local indigenous people, ethnographically known as Aónikenk or Tehuelches meridionales, introducing significant changes to their settlement patterns. Institutionally, indigenous peoples were circumscribed into specifically designed reserves. The archaeological record shows that particular individuals chose to marginalize themselves from these changes, both spatially and as a strategy to adapt to the new circumstances brought by the arrival of the stockbreeding community. These strategies are little known, as evidence of them was plunged into an “historical silence.” The analysis of two sites, Puesto Yatel and Puesto Quintillán, provides a wide range of material culture evidence for these processes, including architectural features, chipped-glass technology (scrapers), metal, wood, lithic technology, and the archaeofaunal record. This new archaeological evidence is crucial for gaining a detailed understanding of 19th- and 20th-century indigenous communities in Patagonia. "

The use of Historical sources for interpreting, explaining and evaluating archaeological contextsand/or social processes has been a common practice in Patagonian Archaeology. On the other hand, Archeology as a source for hypothesis in History has not been frequently considered. This situation may be explained by the historical relationship between both disciplines, where archaeologists havefrequently needed documental sources, but historians rarely needed archaeological interaction. Nevertheless, Archaeology represents an important source for interpreting historical regional processes. In the post-contact centuries, even during the 20th century, historical sources leadthe understanding of the Patagonian past scenario and refer specially to the coastal territory leaving the inland almost unreferenced. This situation suggests the necessity to use the archaeological record, in order to understand and explain more deeply the processes under study.This paper proposes that Archaeology has the potential to generate hypothesis in order to be tested in the Historical field. Two study cases are presented herein; one in Neuquén (northern Patagonia) and the other in Santa Cruz (southern Patagonia).

Research conducted at the Strobel plateau area (Santa Cruz Province) is directed to assess the population dynamics of the area in broad chronological and spatial scales. In this paper we present the analysis of a lithic bolas assemblage associated to Puesto Yatel site, occupied during recent historical moments of the peopling of the area. The lithic bolas assemblage was originally recorded in a small lake setting, most likely showing tools lost in hunting activities. The assemblage is described and key implications for the indigenous historical peopling of the area are commented.

Camusu Aike aporta a la discusión sobre la variabilidad de contextos en los que fue empleada esta
tecnología desde fines del siglo XIX y siglo XX. La evidencia muestra la manufactura, uso sobre
cuero y descarte de los raspadores y, sobre la base de la distribución lineal de los hallazgos, se
infiere la presencia de toldos. Se compara la información con la obtenida en sitios de adscripción
indígena ubicados en el lago Strobel, caracterizados por el aislamiento familiar rural mediante
estrategias individuales no institucionalizadas. Se contribuye así con el conocimiento de las

Nacional así como también la ocupación ganadera del territorio de Santa Cruz.

"GLASS AND STONEWARE SCRAPERS IN THE TEHUELCHE (AONIKENK) RESERVE OF CAMUSU AIKE: CONTRIBUTIONS TO XIX AND XX CENTURY INDIGENOUS POPULATIONS STUDIES IN SANTA CRUZ PROVINCE" The technological and functional analyses of glass and stoneware scrapers recovered from two archaeological sites located in the Tehuelche (Aonikenk) Reservation, nowadays Community, of Camusu Aike contribute to the discussion of the variability of contexts in which this technology was used towards the end of the XIX century and the XX century. The evidence shows the scraper manufacture, hide working, and discard. Based on the lineal display of the findings we infer a toldo type distribution pattern. We compare this information with that of other two sites located at Strobel lake. These are characterized by rural-familiar isolation produced by individual non-institutional strategies. We thus contribute to the knowledge of indigenous peoples during times when National State-imposed changes and the growing stock-breeding occupations were consolidated in the Santa Cruz province.

In this paper, an outline of the main results of the archaeological research carried out in Cardiel Lake and Strobel Lake basins in Southam Patagonia (Argentina), is presented. The study is focused on the Iast 2500 14C yem BP. The evidence that has been gathered points to the existence of significant differences in the use of diverse environmental settings across the region by the prehistoric populations. Moreover, the proposed population dynamics indicates the logistical integration of close and distant spatial settings into a broad supra-regional circuitt , and this allows the discussion of the increasingly hierarchical spatial organisation of he aboriginal populations of Southern Patagonia during the Late Holocene.

In this paper information is presented regarding new rock art sites located in the south of Lake Strobel Plateau. This information allows the discussion of the internal variability in the use of this plateau by human groups. Its possible
causes are analyzed, including size of concentrations, time elapsed between the execution of different engravings and differences in space use in relation to different ways of access. In addition, hypotheses that were presented in previous articles and that refer to a possible population convergency during the Late Holocene in Lake Strobel Plateau are discussed.
