Over the past 20 years, collaboration has become an essential aspect of archaeological practice in North America. In paying increased attention to the voices of descendant and local communities, archaeologists have become aware of the persistent injustices these often marginalized groups face. Building on growing calls for a responsive and engaged cultural heritage praxis, this forum article brings together a group of Native and non-Native scholars working at the nexus of history, ethnography, archaeology, and law in order to grapple with the role of archaeology in advancing social justice. Contributors to this article touch on a diverse range of critical issues facing Indigenous communities in the United States, including heritage law, decolonization, foodways, community-based participatory research, and pedagogy. Uniting these commentaries is a shared emphasis on research practices that promote Indigenous sovereignty and self-determination. In drawing these case studies together, we articulate a sovereignty-based model of social justice that facilitates Indigenous control over cultural heritage in ways that address their contemporary needs and goals.

This report focuses on the morphometric and elemental analysis of glass beads collected from an adobe structure (CA-SCR-217H-T) at Mission Santa Cruz, which operated between 1791 and the 1830s in the colonial province of Alta (upper) California. Previous chemical research established a chronological framework for opacified beads collected from sites in Canada, the Great Lakes region, and the southeastern United States. Testing the viability of this chronological framework for California, we analyzed 100 white glass beads using a conventional typology and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS)—the first application of LA-ICP-MS to a California mission. We present the results of the LA-ICP-MS study and then briefly comment on the potential for LA-ICP-MS to refine chronologies associated with colonial missions and other postcontact sites.

This article emerged as the human species collectively have been experiencing the worst global pandemic in a century. With a long view of the ecological, economic, social, and political factors that promote the emergence and spread of infectious disease, archaeologists are well positioned to examine the antecedents of the present crisis. In this article, we bring together a variety of perspectives on the issues surrounding the emergence, spread, and effects of disease in both the Americas and Afro-Eurasian contexts. Recognizing that human populations most severely impacted by COVID-19 are typically descendants of marginalized groups, we investigate pre- and postcontact disease vectors among Indigenous and Black communities in North America, outlining the systemic impacts of diseases and the conditions that exacerbate their spread. We look at how material culture both reflects and changes as a result of social transformations brought about by disease, the insights that paleopathology provides about the ancient human condition, and the impacts of ancient globalization on the spread of disease worldwide. By understanding the differential effects of past epidemics on diverse communities and contributing to more equitable sociopolitical agendas, archaeology can play a key role in helping to pursue a more just future.

To understand the implications of archaeological site recording practices and associated inventories for studying Indigenous persistence after the arrival of Europeans, we examined the documentary record associated with nearly 900 archaeological sites in Marin County, California. Beginning with the first regional surveys conducted during the early 1900s and continuing into the present, the paper trail created by archaeologists reveals an enduring emphasis on precontact materials to the exclusion of more recent patterns of Indigenous occupation and land use. In assessing sites occupied by Indigenous people from the late sixteenth through the mid-twentieth centuries, we discuss how the use of multiple lines of evidence—including temporally diagnostic artifacts, chronometric dating techniques, and historical documentation—may help illuminate subtle but widespread patterns of Native presence that have been obscured by essentialist assumptions about Indigenous culture change. Our findings further reveal the shortcomings of traditional site recording systems, in which archaeologists typically categorize sites within the prehistoric-protohistoric-historic triad on the basis of commonsense decisions that conflate chronology with identity. Instead, we argue for recording practices that focus specifically on the calendric ages of occupation for any given site.

This paper examines the marine reservoir effect for Tomales Bay, a 25.5-km-long tidal estuary along the northern coast of California. We determined the regional ∆R through radiocarbon (14C) measurements of pre-1950 shells from a museum collection as well as archaeologically recovered shell samples from a historical railroad grade of known construction date. These results are compared against four sets of paired shell and bone samples from two local archaeological sites. Our results indicate little spatial variation along the inner bay, but the proposed ∆R value is lower than those previously reported for nearby areas along the Pacific Coast. We also note potential variability in regional ∆R of approximately 200 14C years for the late Holocene, and comparison with an older paired bone and shell sample points toward more significant temporal variation earlier in time.

Indigenous negotiations of European colonialism in North America are more complex than models of domination and resistance reveal. Indigenous people—acting according to their own historically and culturally specific ways of knowing and being in the world—developed strategies for remaking their identities, material choices, and social configurations to survive one or multiple phases of colonization. Archaeologists are making strides in documenting the contingencies and consequences of these strategies, yet their focus is often skewed toward sites of contact and colonialism (e.g., missions and forts). This article examines places of refuge for native people navigating colonial programs in the San Francisco Bay area of California. I use a resistance-memory-refuge framework to reevaluate resistance to Spanish missions, including the possible reoccupation of landscapes by fugitive orfurloughed Indians. Commemorative trips to shellmounds and other refuges support the concept of an indigenous hinterland, or landscapes that, in time, provided contexts for continuity and adjustment among Indian communities making social, material, and economic choices in the wake ofmissionization. By viewing colonialism from the outside in, this reoriented approach can potentially enhance connections between archaeological and Native American communities.

The periodization used to distinguish sites and artifacts as "prehistoric" or "historic" translates to the selection of field methods and analytical techniques. This comes at the expense of developing new approaches to track continuities and adjustments in Native American site use, technologies, and other cultural traditions, such as mobility across an artificial divide between prehistory and history. To evaluate the mobility of Coast Miwok people in colonial San Francisco Bay, California, this article presents an experimental technique that compares radiocarbon and geochemical data from a Late period Phase 2(A.D. 1500-1800) shellmound (CA-MRN-114) to baptismal records from Spanish missions (A.D.l 776-1830s). Supported by eyewitness accounts of native fugitivism, furlough, and foraging at the missions, Coast Miwok baptisms before 1817 are at their lowest during traditional times of mussel harvests. After 1817, a different pattern is examined vis-d-vis the colonial landscapes taking shape in the region. Radiocarbon, geochemical, and documentary evidence supports the conclusion that seasonally oriented Coast Miwok mobility involving the collection of shellfish continued even during missionization. With further refinement, the proposed methodological framework holds promise for documenting patterns that often go unseen in the historical record and enhancing the archaeology of colonialism in North America.

This article advocates for a comparative approach to archaeological studies of colonialism that considers how Native American societies with divergent political economies may have influenced various kinds of processes and outcomes in their encounters with European colonists. Three dimensions of indigenous political economies (polity size, polity structure, and landscape management practices) are identified as critical variables in colonial research. The importance of considering these dimensions is exemplified in a case study from California, which shows how small-sized polities, weak to moderate political hierarchies, and regionally oriented pyrodiversity economies played significant roles in the kinds of colonial relationships that unfolded. The case study illustrates how the colonial experiences of Native Californians differed from those of other tribal groups that confronted similar kinds of colonial programs involving Franciscan missionaries elsewhere in North America. The article stresses that the archaeology of colonialism is not simply an arcane academic exercise but, rather, has real-life relevancy for people who remain haunted by the legacies of colonialism, such as those petitioning for federal recognition in California.

This paper presents a set of accelerator mass spectrometry (AMS) radiocarbon dates obtained from various archaeological samples collected from 3 shellmounds—CA-MRN-114, CA-MRN-115, and CA-MRN-328—within China Camp State Park, Marin County, California, USA.
