Despite considerable developments in the archaeological application of lidar for detecting roads, less attention has been given to studying road morphology using lidar. As a result, archaeologists are well equipped to locate but not thoroughly study roads via lidar data. Here, a method that visualizes and statistically compares road profiles using elevation values extracted from lidar-derived digital elevation models is presented and illustrated through a case study on Chaco roads, located in the US Southwest. This method is used to establish the common form of ground-truthed Chaco roads and to measure how frequently this form is across non-ground-truthed roads. This method is an addition to the growing suite of tools for documenting and comparing roads using remotely sensed data, and it can be particularly useful in threatened landscapes where ground truthing is becoming less possible.

In recent years, the field of paleogenomics has grown into an exciting and rapidly advancing area of scientific inquiry. However, scientific work in this field has far outpaced the discipline's dialogue about research ethics. In particular, Indigenous peoples have argued that the paleogenomics revolution has produced a "vampire science" that perpetuates biocolonialist traditions of extracting Indigenous bodies and heritage without the consent of, or benefits to, the communities who are most affected by this research. In this article, we explore these ethical issues through the case study of a project that sequenced the ancient DNA (aDNA) of nine Ancestral Puebloan people from Chaco Canyon, New Mexico. By providing a "thick description" of this controversy, we are able to analyze its metanarratives, periodization, path dependency, and historical contingencies. We conclude that the paleogenomics revolution needs to include an ethical revolution that remakes the field's values, relationships, forms of accountability, and practices. [ABSTRACT FROM AUTHOR]

Abstract: The use of violence as a means of social control among higher status members of the Ancestral Pueblo is explored by using data derived from the burials and the burial context of several sites between AD 850 and 1300. High-status burials, while relatively rare in the archeological record, are of interest because of the role the individuals are assumed to have played in the culture. It has been suggested that there were “elites” among the Ancestral Pueblo during a particularly volatile period that corresponds with the growth, development, and decline of Chacon Canyon and to a lesser extent Aztec Ruins, two major political and ritual centers. Using a bioarchaeological approach that integrates the human remains with the archeological context, burials from Chaco Canyon were compared with burials from other sites in the region based on demographic (age and sex), nutritional (stature), activity (robusticity and entheses), health (pathological conditions), violence (cranial trauma), and cultural (mortuary pattern) patterns. Crucial for expanding our understanding of the role of hierarchy and social control in the Pueblo world, these data suggest that there were high-status individuals who functioned as political and ceremonial leaders.
