Graduate schools provide students opportunities for fieldwork and training in archaeological methods and theory, but they often overlook instruction in field safety and well-being. We suggest that more explicit guidance on how to conduct safe fieldwork will improve the overall success of student-led projects and prepare students to direct safe and successful fieldwork programs as professionals. In this article, we draw on the experiences of current and recent graduate students as well as professors who have overseen graduate fieldwork to outline key considerations in improving field safety and well-being and to offer recommendations for specific training and safety protocols. In devising these considerations and recommendations, we have referenced both domestic and international field projects, as well as those involving community collaboration.

The ease of digital data capture and the proliferation of concepts such as the “data deluge” suggest that modern researchers are drowning in datasets. Yet citations of archaeological datasets are few and far between, pointing to low rates of data reuse. This article explores the difficulties that surround data reuse in large-scale regional research, including the cost and coordination necessary to extract useful data from digitized PDF reports. The amount of correction and enhancement matches the effort needed to undertake a small field survey project and can only be circumvented with a thoughtful application of computer-assisted text analysis. Missing data in excavation report PDFs are not only intractable but also insidious due to their concealed nature, leading to poor outcomes in terms of (re)use. Consequently, the degree of data reuse in archaeology has been overestimated.

For the first time in North American archaeology, absorbed residue analysis was conducted on multiple samples from the same vessel, a complete Mississippi Plain jar from Angel Mounds (12Vg1). This approach provided comprehensive, residue-based interpretations of the form and function of a single pot. The Mississippi Plain jar was recovered from a burnt house floor along with the broken remains of a similar vessel and burnt maize. Qualitative and quantitative analyses of absorbed lipid residues were performed on four different parts of this vessel to determine its contents and function. Comparison of absorbed residues from the pot and soil lipids was used to determine whether the pot was buried with contents intact. The results indicate that this vessel was used to cook a mixture of riverine (lean fish or shellfish) and plant resources, probably including maize. Diterpenoid biomarkers were also present, suggesting that conifer resin was used either to seal the pot or as a flavoring. The jar, though deposited whole, was probably not buried with contents intact.

MOLA (Museum of London Archaeology) is one of the leading archaeological companies in the UK. It provides professional archaeological services and implements award-winning community engagement programs with a high-profile online presence. Its Facebook page is an important communication channel, serving the organization in raising public awareness, reaching the widest audiences, and engaging with the community. MOLA has developed a strategic approach to its archaeological communication on Facebook by ensuring regular updates of its research and by providing rich archaeological content aligned with media campaigns of the most notable archaeological excavations. This strategy helps the organization build a steady and engaged community of interest. The use of social networks for public engagement, the possibilities of rapid dissemination, and the challenges of ensuring sustainable online participation via social networks resonate with major concerns discussed by different researchers in the field. This review explores MOLA's Facebook page, seeking to showcase how the archaeological organization communicates through Facebook on a day-to-day basis and to reveal how Facebook users react to different kinds of archaeological content through measurable metrics.

Microartifact analysis, the study of the density and distribution of tiny (yet visible) fragments of ceramics, bone, worked stone, and other microartifacts, offers a promising solution to the challenges of determining the location and nature of activity areas at archaeological sites. In spite of the fact that microartifact analysis has been successfully applied at sites in North America and the Middle East, archaeologists have yet to recognize the utility of this methodology in most of the rest of the world. The purpose of this article is, therefore, to test whether this methodology can be profitably applied in the southern Andes. To do so, we describe the results of microartifact sampling, processing, and analytical techniques that we applied to two phases of occupation at the site of Tumilaca la Chimba in southern Peru. The results of the research outlined in this article suggest that microartifact analysis is an effective analytical technique that can contribute greatly to archaeological praxis.

Spatial and shape data represented by 3D digital models have become a central component of our archaeological datasets. Immersive visual and audio interaction with these models offers an intuitive way to use these data. The mixing of the virtual with the real world suits archaeological work particularly well, and the technologies of augmented reality (AR) and mixed reality (MR) enable this type of interaction. Much past work on these technologies has involved public engagement, but they also hold the potential for valuable deployment directly in archaeological practice and research, especially the seamless integration offered by MR. This review examines the range of experiments archaeologists are currently undertaking with AR and MR, and it looks to the future applications of these technologies.

The value of new archaeological knowledge is strongly determined by how credible it is, and a key measure of scientific credibility is how replicable new results are. However, few archaeologists learn the skills necessary to conduct replication as part of their training. This means there is a gap between the ideals of archaeological science and the skills we teach future researchers. Here we argue for replications as a core type of class assignment in archaeology courses to close this gap and establish a culture of replication and reproducibility. We review replication assignments in other fields and describe how to implement a replication assignment suitable for many types of archaeology programs. We describe our experience with replication in an upper-level undergraduate class on stone artifact analysis. Replication assignments can help archaeology programs give students the skills that enable transparent and reproducible research.

This paper outlines several outreach initiatives that the Proyecto de Investigación Arqueológico Regional Ancash (PIARA) established to address the challenges of heritage preservation at the prehistoric archaeological site and rural community of Hualcayán, located in rural highland Ancash, Peru. We discuss three projects—a heritage festival, a textile enterprise, and an oral history project—that were designed and executed through a collaboration between PIARA and the Hualcayán community. We find that these “co-creative” projects encourage local stakeholders to discover and define for themselves the value of both their ancient and modern heritage. Reflecting on the outcomes from these projects, we discuss the co-creative approach as an effective strategy for improving the preservation of archaeological remains and enhancing the livelihood of the modern community.

The methodical recording and representation of spatial data are central to archaeological fieldwork and research. Until recently, centimeter-level precise geolocation equipment was the exclusive domain of researchers who could afford setups costing tens of thousands of dollars. However, high-quality measurements are being made more accessible by rapidly evolving technologies. These new tools, when used together with mobile technology for efficiently recording field data, open up the possibility of capturing the precise location of every find during an archaeological surface survey. An important step in reaching the desired outcome—centimeter-level recording for all—is experimentation with a variety of emerging low-cost setups. Accordingly, we tested the Reach and Reach RS, differential global navigation satellite systems (dGNSS) equipment produced by the company Emlid, during a surface survey in Armenia in June 2018. Our field application demonstrates that the use of dGNSS is already possible and that the described advances in precision enable improved recording and representation of spatial data.

Universities struggle to provide meaningful education and mentorship to Native American students, especially in STEM fields such as archaeology and geography. The Native American Summer Mentorship Program (NASMP) at Utah State University is designed to address Native student retention and representation, and it fosters collaboration between mentors and mentees. In spring 2020, as university instruction went online due to the COVID-19 pandemic, NASMP mentors were faced with adapting hands-on activities and face-to-face interaction to an online format. Using our Water Heritage Anthropological Project as a case study, we show how virtual archaeological, archival, spatial, and anthropological labs can be adapted for online delivery. This approach may be especially useful for reaching students in rural settings but also for engaging students in virtual or remote research in the field sciences.

This research aims to investigate the potential use of three-dimensional (3D) technologies for the analysis and interpretation of heritage sites. This article uses different 3D survey technologies to find the most appropriate methods to document archaeological stratigraphy, based on diverse environmental conditions, light exposures, and varied surfaces. The use of 3D laser scanners and dense stereo matching (DSM) techniques is now well established in archaeology. However, no convincing comparisons between those techniques have been presented. This research fills this gap to provide an accurate data assessment for the Las Cuevas site (Belize) and represents a starting point for the definition of a sharable methodology. Tests in Las Cuevas were conducted to compare both accuracy and density reliability in cave environments using two different techniques: triangulation light laser scanner and DSM. This study finds that DSM is the most economical, portable, and flexible approach for the 3D documentation of archaeological sites today. In fact, DSM allows the 3D documentation process to be done more efficiently, reducing both data acquisition and processing time. Nonetheless, the quantitative comparison presented in this paper underscores the need to integrate this technique with other technologies when the data acquisition of micro-stratigraphy is required.

Small bone fragments have often been interpreted as the residues of stews or grease extraction. In international historical archaeological research, stew interpretations have often focused on enslaved or underclass groups or on those who had limited access to sufficient amounts of food or faced nutritional deficiencies. These analyses have widely been uncritical, and the small fragment sizes can be better explained as the products of taphonomic processes such as weathering, trampling, and carnivore scavenging. This work presents results from experimentally chopped long bones from cows, sheep, goats, and pigs that identify butchery and fracture patterns that can be used to evaluate past stew interpretations and provide comparative models for future analyses.

The Permian Basin Programmatic Agreement (PA) is an alternative form of Section 106 compliance offered mainly to the oil and gas industry in southeastern New Mexico for projects located on Bureau of Land Management (BLM) land. Proponents of projects within the PA area may contribute to a dedicated archaeological research fund in lieu of contracting for project specific archaeological surveys, provided their proposed projects avoid recorded archaeological sites. Dedicated funding goes toward research on the archaeology and history of southeastern New Mexico. The PA calls for the consulting parties to evaluate its effectiveness during its seventh year of implementation. As a result of that recent evaluation in May 2015, the PA will be extended for 10 additional years. We discuss the reasons for the PA, successes and missteps during its first seven years, and ways that the Permian Basin PA might be used as a model elsewhere.

Daily data collection during archaeological fieldwork forms the basis for later interpretation and analysis. Across the world, we observe a wide variety of digital data collection methods and tools employed during fieldwork. Here, we detail the daily practices at four recent survey and excavation projects in the South Caucasian country of Armenia. As archaeology continues to become ever more digital, it is useful to consider these day-to-day recording processes at a typical field project. We provide details on both the types of data collected and the ways they are collected so as to foreground these topics. Finally, we reflect on how our work is currently impacted by digital changes and how it may continue to change in the future.

Preservation knowledge is important for those preparing archaeological collections for curation or requesting access to collections for research. Literature about the fields of archaeological conservation and curation is plentiful, but there are scant resources that offer a basic introduction to the knowledge needed to facilitate preservation of and access to archaeological collections. Much of the literature focuses on conservation in the field and in the lab. Archaeological curation standards and the importance of sustainable management of archaeological collections also are well documented. In contrast, this article serves as an introductory guide to preventive care, specifically to the agents of deterioration and the storage considerations that affect preservation of and access to archaeological collections. Collections specialists who work in museums, government repositories, or historical societies, as well as field archaeologists, academic archaeologists teaching and conducting research on collections, and descendant communities in tribal historic preservation offices and other repositories will find this guide useful as a reference and teaching resource.

Human skeletal remains hold a wealth of information about past life-ways, but their documentation and recovery from archaeological contexts is challenging. Four challenges face bioarchaeological field work: poor skeletal preservation; complex mortuary traditions; sub-par excavation conditions; and excavation time limits. Poor preservation often prevents the collection of metric data from skeletons. This project tested whether a bioarchaeologist with basic photography skills and excavation equipment could address these challenges using photogrammetry. Photogrammetry was employed at the ancient Maya sites of Say Kah and Chan Chich, both located in northern Belize, to document human skeletal remains and their archaeological contexts. Steps are provided for implementing photogrammetry in the field, as well as addressing challenges for using the technique during burial documentation. This project produced only one adequate 3-D model and no metric data could be collected. Overall, photogrammetry seems to be a promising method for bioarchaeological research because it is low-cost, effective, and fairly straightforward to learn. The technique was faster than traditional line drawing, but sub-par excavation conditions and dark, small spaces hindered the creation of useful models. Photogrammetry provides an excellent alternative to traditional documentation addressing the challenges of poor skeletal preservation and holding potential for unraveling complex mortuary traditions.

This research employs machine learning (Mask Region-Based Convolutional Neural Networks [Mask R-CNN]) and cluster analysis (Density-based spatial clustering of applications with noise [DBSCAN]) to identify more than 20,000 relict charcoal hearths (RCHs) organized in large “fields” within and around State Game Lands (SGLs) in Pennsylvania. This research has two important threads that we hope will advance the archaeological study of landscapes. The first is the significant historical impact of charcoal production, a poorly understood industry of the late eighteenth to early twentieth century, on the historic and present landscape of the United States. Although this research focuses on charcoal production in Pennsylvania, it has broad application for both identifying and contextualizing historical charcoal production throughout the world and for better understanding modern charcoal production. The second thread is the use of open data, open source, and open access tools to conduct this analysis, as well as the open publication of the resultant data. Not only does this research demonstrate the significance of open access tools and data but the open publication of our code as well as our data allow others to replicate our work, to tweak our code and protocols for their own work, and reuse our results.

As lidar becomes a regular part of surveying, ground-based platforms (handheld, mobile, and terrestrial lidar) and airborne platforms (piloted aircraft) are being joined by unpiloted aerial vehicle (UAV)–acquired lidar. We present a method for leveraging UAV-acquired lidar data with data collected using different lidar platforms (terrestrial and piloted aircraft), at a range of resolutions (1 to +1,000 points per m2) and geographic scales. We use these instruments to document a dry-masonry stone wall enclosing a religious precinct within the royal center at Kealakekua, Kona District, Hawai'i Island. Prior to European contact in AD 1779, Kealakekua was the center of the island-wide polity during the annual Makahiki festival. Results of this study suggest that when the wall was constructed around AD 1640, it was the largest structure ever built on the island of Hawai'i as well as a strong material expression of the power of state religion and the Makahiki rituals.

This article introduces a special volume of Advances in Archaeological Practice dedicated to the interpretation and presentation of archaeology. It provides an overview of several essays that came out of a session at the European Association of Archaeology Conference in 2017, which focused upon how interpretation can be implemented within daily practices of (cultural resource management) archaeology in a way that provides heritage value. We bring the arguments together into a call for a creative, interpretive archaeology that does not take compliance or academic publications as its end goal but will speak to a far wider range of audiences through the development and presentation of stories and narratives that truly engage and inspire people. We argue that this can be achieved by implementing “emotion design” methods that dynamically differentiate between information, message, emotion, and media, by working closely together with creatives, interpretive experts, communities, and partners and, ultimately, by integrating interpretation firmly at the core of planning processes, archaeological workflows, and our daily practices.

Stone alignments, including tipi rings and drive lines, are abundant on the northern Plains and adjacent Rocky Mountains, but they have been notoriously difficult to date. This paper applies luminescence dating to sediments directly underneath the rocks to estimate the age of placement of the rock. This is based on the assumption that before the rock was emplaced, turbation processes brought sufficient grains to the surface, where sunlight reset the signal. Single-grain dating of potassium feldspars allowed isolation of these original well-bleached grains, which by now have built up a signal because the rock prevents transfer to the surface. Plotting the number of original well-bleached grains with depth showed that these grains were concentrated just under the rock and decreased with depth. This is what would be predicted if the assumption is true. Dates were derived from several samples from Kutoyis in north central Montana, from Whitewater in eastern Montana, and from several sites in northwestern Wyoming. Many samples from Kutoyis and Wyoming dated to the last 600 years, but some samples from both places were more than 2,000 years old. The Whitewater features also dated to around 2,000 years ago. The ages are consistent with the cultural history of the areas.
