The Role of GPR in Community-Driven Compliance Archaeology with Tribal and Non-tribal Communities in Central California

For tribes whose preservation values and mitigation strategies for managing cultural heritage are built on an ethic of avoidance and minimal disturbance, geophysical technologies can be key components of the research design. These technologies, most notably ground-penetrating radar, have been used with great success in identifying and evaluating the depth, extent, and composition of some of those resources for heritage research and management purposes, easing tensions when working with sensitive ancestral places. Additionally, research in archaeological geophysics has shifted from feature finding in order to excavate targets of interest to the recognition that geophysical survey can provide data and interpretations for whole sites and landscapes complementary to or beyond that of excavation, especially regarding the intactness and sensitivity of cultural heritage sites. This use of geophysics as a primary method for research rather than a precursor to archaeological research has empowered tribes with another tool to advocate for low-impact investigation of ancestral sites and landscapes that position tribes as pro-science. Geophysical technologies provide scientifically rigorous yet minimally impactful strategies for investigating heritage while satisfying the requirements of academic and compliance archaeology in ways that can also be culturally appropriate for a much broader spectrum of tribal cultural heritage under consideration.

Crafting Country

Based on ten years of surveys and excavations in Nyiyaparli country in the eastern Chichester Ranges, north-west Australia, Crafting Country provides a unique synthesis of Holocene archaeology in the Pilbara region. The analysis of about 1000 sites, including surface artefact scatters and 19 excavated rock shelters, as well as thousands of isolated artefacts, takes a broad view of the landscape, examining the distribution of archaeological remains in time and space. Heritage compliance archaeology commonly focuses on individual sites, but this study reconsiders the evidence at different scales – at the level of artefact, site, locality, and region – to show how Aboriginal people interacted with the land and made their mark on it. Crafting Country shows that the Nyiyaparli ‘crafted’ their country, building structures and supplying key sites with grindstones, raw material and flaked stone cores. In so doing, they created a taskscape of interwoven activities linked by paths of movement.
