Archaeologists studying shell assemblages from prehistoric sites along the Pacific coast of North America have been interested in the influences of collecting intensity and environmental variability on California mussel (Mytilus californianus) size. To determine the variation in mussel size within a shell assemblage, researchers have developed a variety of proxies of mussel valve length based on measurements of morphological features occurring at or near the valve’s umbo. We propose four additional measurements that can serve as proxies and evaluate their correlation with valve length using regression analysis. Of the four, anterior adductor scar length has the strongest correlation, and we present two examples of its application. We also evaluate a popular visual technique based on a set of outline drawings of valves of varying lengths, and we found that it systematically underestimated valve length but could be useful under certain circumstances. We conclude that the selection of a particular proxy of mussel valve length depends on the nature of the mussel shell assemblage being studied and the research context.

Over the past few years, the lead author has had the opportunity to excavate multiple large sites in California, working on behalf of developers to keep their projects in compliance with their permits. She also worked in conjunction with local tribes to resolve burial issues with each excavation. During these excavations, she observed the challenges that the tribes encountered when dealing with fast-paced cultural resource management (CRM) projects where burial retrieval and a shortage of resources were the norm. For many years, archaeologists have viewed CRM as only dealing with the material culture of the past; however, archaeologists also consult and work with living cultures. This article will address the endemic problem in CRM that stems from a lack of planning, preparation, resources, and training and how it affects the burial excavations that archaeologists and tribes encounter in the CRM setting. It will also look for solutions to remedy a long-broken system that continues to ignore existing laws set in place to protect resources, as well as the relationships between the Native American community, agencies, researchers, and land developers.

Field safety is being taken more seriously across the cultural resource management (CRM) industry as CRM companies seek to be in compliance with their clients’ health and safety programs and to keep employees safe. Many universities also have organizational health and safety programs designed to protect students and employees, but academic archaeology is routinely conducted without adequate risk management planning. Risk management will be a workplace concern for aspiring archaeologists after graduating from college, which is why it is important for academic archaeology to meet industry standards. Archaeology can learn a great deal about fieldwork risk management from the outdoor recreation industry, which emphasizes building leadership skills rather than following proscribed rules and regulations to mitigate the myriad hazards in the field. This article provides some suggestions that academic archaeologists can use to apply risk management concepts from CRM and the outdoor recreation industry to academic projects in order to comply with university requirements and the Occupational Safety and Health Administration (OSHA), as well as to teach students how to be safe in the field.

A consistent challenge in community and collaborative archaeologies has been the appropriate identification and understanding of project constituencies. A key step in stakeholder analysis is understanding and harmonizing the goals of archaeological work to the social role of the institutions for which we work. To illustrate the value of such a stance, we examine on-campus archaeology programs at colleges and universities, arguing that treating students as vital stakeholders is an important ethical obligation for both researchers and administrators. Including students as stakeholders in campus archaeology provides pedagogical benefits and a meaningful way to instill an appreciation of archaeology in an important constituency of potential voters and future decision-makers. We present a case study from Santa Clara University (SCU), reporting results of an online survey of undergraduates that was intended to gauge community interests in campus archaeology and heritage. We also detail activities undertaken by SCU's Community Heritage Lab in response to survey findings in order to raise the profile of the archaeological and other heritage resources on our campus.

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.

This article explores the use of specially trained canines to detect the location of human burials in nonmodern archaeological contexts. It discusses the history of the discipline, training and field methods, the importance of developing a working relationship with descendant communities, project examples, an assessment of canine detection effectiveness, and ways to select a canine detection team. The article highlights how the application of canine detection training and protocols to the archaeological record makes it possible to locate potential precontact Native American burial areas without ground disturbance. In some cases, probable burial areas located by canines can be confidentially mapped to ensure avoidance during upcoming construction projects. For a variety of reasons, many Native American communities have been wary of embracing this new method to locate ancestral burials. Today, however, canine detection is widely accepted by many tribal groups in California to locate ancestral burials that might be impacted by construction. Although additional controlled studies and rigorous field laboratory experiments are needed to understand the range of variation in efficacy fully, available results in both North America and Europe demonstrate that specially trained canines can often accurately locate human burials that are more than a thousand years old to within a few meters.

YouTube is now a common public face for archaeology and history. Professionals and amateurs alike make videos, whether it be for monetary gain, outreach, or a combination of the two. The YouTube channel Ghost Town Living is no exception. It features the town's current owner, Brent Underwood, modifying the “abandoned” mining town of Cerro Gordo into a tourist destination. During this process, as is documented in his videos, it becomes clear that Underwood is not only conserving the town but also transforming it into an amalgam of California's mining history. In doing so and by presenting it on YouTube, Underwood is sharing the heritage of Cerro Gordo with the public. Although Underwood is not an archaeologist and is not pretending to be one, some of the methods employed are far from “best practice.” Despite this, I argue that perhaps the overall goals and processes of Underwood should be encouraged to some degree, and in this case, that they do more good than harm for the “preservation” of Cerro Gordo.

Legal reforms in California are reshaping archaeological education and professional training in ways that may soon warrant national attention. These changes challenge traditional pedagogical models, particularly in bachelor’s and master’s degree programs that have long served as entry points into cultural resource management (CRM) careers. Drawing on one of the most extensive surveys of CRM organizations in California, this article examines how employers are responding to this evolving landscape. The data reveal a demand for field experience, local familiarity, knowledge of relevant laws, and interpersonal skills. We contextualize these findings within broader efforts to reform training and research models in California and discuss tensions in this shifting terrain. We advocate for a new public archaeology that redefines training and professional pathways through collaboration, accountability, and a deeper commitment to the communities that archaeology serves.

In 2003, the Autry Museum of the American West merged with the Southwest Museum of the American Indian, which housed the second largest collection of Native American objects in the country. Included within this collection is the Braun Research Library Collection, which consists of works of art on paper, rare books, scholarly publications, manuscripts, photographs, correspondences, maps and sound recordings, and other archival materials, many of which relate to the early development of the disciplines of archaeology and anthropology in the United States. For over a century, both national and international researchers have used the museum's collections and archival materials with a relative open access. However, due to the culturally sensitive nature of many of these collections and the growth of how information can be made accessible, the Autry institution is currently developing procedures that affect access, especially for those researchers who wish to study archaeological archives. Staff from multiple departments are collaborating on addressing these concerns, including developing new policies while improving access to Native American tribes, communities, and researchers in preparation for the new off-site Autry Resources Center and storage facility where the collection will be housed in the future.

The field of anthropological archaeology in North America is undergoing significant changes, particularly within academia, with an increased focus on and inclusion of Indigenous perspectives. Concomitant with the reorientation of archaeological practice that centers on Indigenous voices, concerns, and sensibilities is a subsequent reorientation in the training of the next generation of practitioners. This article highlights an example of a collaborative archaeological field school developed by, with, and for the Amah Mutsun Tribal Band, the Amah Mutsun Land Trust, and the University of Oregon. We document the long-term use of collaborative field schools to train the next generation of Tribal and non-Tribal archaeologists in archaeological field methods and collaborative research practices with, for, and by Indigenous communities.

In the desert of southeastern California, the geological and archaeological remnants of a once massive lake, Lake Cahuilla, are still visible. One of the most distinctive features marking Lake Cahuilla's relic shorelines is a series of rock fish trap features that, in some cases, stretch across thousands of square meters. These fish traps are severely understudied, and systematic archaeological survey can help scientists reconstruct the dynamic human-environmental history of the region. The large number of fish traps along with the rocky desert terrain, however, make traditional pedestrian archaeological surveys both difficult and inefficient. We used unmanned aerial vehicle (UAV) technology along with traditional archaeological methods to conduct surveys and identify patterning in the shapes, orientations, and frequencies of fish traps. Our study demonstrates the potential of emerging archaeological field technology to better understand the nature of human-environmental ecodynamics through time and space.

Historic archaeological resources in the American West are increasingly at risk of loss because of prolonged droughts, wildfires, earthquakes, general deterioration, and the negative impact of increasing visitation. Casual visitors regularly remove objects from their original contexts in the landscape, either taking them home as souvenirs or bringing them to local staff because they are concerned about the items disappearing. As a result, many sites of cultural significance are losing the ability to convey the information required for scholarly interpretation and for drafting community and life histories of their past residents. We argue that citizen science and mobile apps specifically designed for site stewardship are viable tools for alleviating negative human impacts on cultural landscapes and enhancing our capacity to record and monitor sites of cultural heritage. We contend that our approach uses an innovative interface, the Citizen Preservationist app, an open-source hybrid mobile/desktop software we developed to foster both current use and protection of archaeological sites and historic parks. We demonstrated the viability of our app by conducting a user study at Bodie, California (ca. 1859–1942), that assessed how this software promotes a sense of stewardship and appreciation for the archaeological heritage of this beloved California State Historic Park.

Advanced 2-D and 3-D computer visualizations are increasingly being used for recording and documentation, analysis, dissemination, and public engagement purposes. Recent technological advances not only considerably improve data acquisition, processing, and analysis but also enable easy and efficient online presentation. This article evaluates the contributions of advanced 2-D and 3-D computer visualization and discusses the potential of 3-D modeling for recording basketry technology and documenting the state of preservation of baskets. It explores the available analysis, integration, and online dissemination tools, using as case studies recently excavated baskets from Cache Cave in southern California. Results indicate that the proposed methodology, which incorporates reflectance transformation imaging visualizations and photogrammetric 3-D models, which are further processed using 3-D modeling software and integrated analysis tools and then transformed to a Web-based format, is a useful addition to the basketry analysis toolkit.
