How Archaeologists Can Effectively and Ethically Cultivate Responsible and Responsive Stewards

The objective of this article is to share how professional archaeologists can leverage their knowledge and influence to develop collectors and amateur archaeologists into responsible and responsive stewards (RRS). This approach furthers the primary purposes of the National Historic Preservation Act as well as the ethics of the Society for American Archaeology. I share my own journey about finding artifacts in the Texas Panhandle, yearning to understand more about them, and how a poster in a gas station led me to visiting a local Stone Age Fair where I met a professional archaeologist. This archaeologist mentor was willing to answer my questions and guide me to greater understanding of archaeological ethics and practice, which prompted me to document everything I had found. In turn, I have shared my experience with many other nonprofessionals. Archaeologist mentors can have great influence if they are willing to meet collectors and amateur archaeologists on their level. Ultimately, collectors and archaeologists share a love of artifacts and a passion for the history behind them.

Towards a dialogical archaeology: an Andean perspective on hermeneutics, interpretation and political praxis

Taking a geopolitical perspective centred in the Argentinian Andes, the authors propose a hermeneutical view of dialogical archaeology. The application of this theoretical and methodological approach to the example of the archaeological site of Huayatayoc (Puna de Jujuy, Argentina) enables an interpretation of the site as a complex woven fabric of diachronic local and scientific practices and narratives. The authors’ work at Huayatayoc provides an example of the potential of this approach for the development of a critical Latin American archaeology, which seeks to acknowledge the multiple interests and narratives of researchers and local communities in dialogue.

Pachuca Obsidian Blades from the U.S. Southwest: Implications for Mesoamerican Connections and Coronado's Mexican Indian Allies

The connection between people in the prehispanic U.S. Southwest / Northwest Mexico (SW/NW) and Mesoamerica is one of the most debated research topics in American archaeology. SW/NW groups used objects from Mesoamerica, but did they also trade for obsidian? Archaeologists have yet to find Mesoamerican obsidian from confirmed prehispanic SW/NW contexts, but here we discuss four green obsidian prismatic blades from New Mexico and Arizona. Using EDXRF spectrometry, we demonstrate that the blades are from the Pachuca source in Mesoamerica. The blades were found at four sites that the Spanish and their Mexican Indian allies used or potentially visited beginning in AD 1540. Using lithic technological organization and historical narratives, we assess the credibility of the different hypothesized models of prehispanic SW/NW-Mesoamerican interaction and obsidian use by the Mexican Indian allies. We suggest that green Pachuca blades would have been traded into the SW/NW if interaction with Mesoamerica had occurred more frequently. We also offer reasons why archaeologists have found so few Mesoamerican obsidian blades at post-1540 sites. This research is relevant because it expands our knowledge about SW/NW-Mesoamerican connections and the Mexican Indian allies of the Spanish, who are an underrepresented group in the archaeological and historical records.

Materials and Methods

To determine the origin of archaeological spindle graphs, and to track the frequency of use of each of several types of graph used to diagram culture change, a sample of North American archaeological literature was examined. Numerous series of monographs and volumes of journals in both the archaeological and the paleontological literature were inspected. If a graph of biological (paleontological) or cultural (archaeological) change was included in a publication, that piece of literature was recorded along with the type of graph included. To record such data, a classification of graph types was developed based on categories of statistical graphs (e.g., bar graph, line graph, pie graph, time range, spatio-temporal rectangle). More than 900 pieces of literature on North American archaeology published between ~1880 and ~1960 were inspected, and more than 450 pieces of literature on paleontology were inspected. Because different graph types are constructed under different guidelines, they require an understanding of graph grammar—the rules for constructing, deciphering, and interpreting graphs.
