Archaeologists are tasked with balancing a call to open data and the need to maintain confidentiality of sensitive archaeological site locations. Low-resolution mapping and data aggregation are the methods most commonly used to hide site locations; however, we understand little of the effectiveness of these practices. Trends in geomasking, obscuring observed geographic points, to anonymize public health data are suggested as a source of methods for sharing archaeological site data. Archaeologists have available to them a number of geomasking methods that balance open data and site security in different ways. Low-resolution mapping at several scales and random direction with fixed radius, random perturbation donut, and Gaussian donut techniques are tested on a set of archaeological site locations. Random perturbation donuts resulted in the best balance between obscuring archaeological locations and conveying observed spatial patterning. Researchers should carefully consider how they convey archaeological location data, as commonly used low-resolution scales may not provide the desired level of obscurity. Researchers should also be explicit as to how and why their methods of site visualization are chosen.

As archaeologists expand the accessibility of legacy data, they have an opportunity to use these datasets to design future research. We argue that legacy data can be a critical resource to help predict characteristics of sites and socioeconomic systems. In this article, we present a combined geographic information system (GIS) and network analysis methodology that turns site location data into testable hypotheses about site characteristics and the organization of regional settlement systems. We demonstrate the utility of this approach with a case study: Bronze Age (2700–1100 BC) settlement patterns in the mining region of Hunedoara in southwest Transylvania, Romania. We leverage unsystematically collected site location information in legacy datasets to develop testable predictions about sites, regional networks, and socioeconomic systems that can be evaluated through future systematic surveys and large-scale excavations. Such testable hypotheses can inform archaeological research design by providing a quantitative basis for determining where to focus research efforts and can also help secure funding and fieldwork permits. The method developed here can be applied in diverse archaeological contexts to reinvigorate legacy data as part of future archaeological research design.

In the past decade, archaeologists have increasingly made use of photogrammetry, the process of creating 3D models from photographs, in a variety of field and lab settings. We argue that we must, as a discipline, develop a consistent methodology to ensure that 3D models are held to a consistent standard, including not only photographic protocol but also the documentation of model accuracy using an agreed-upon measure. To help develop this discussion, we present our system for incorporating photogrammetry into the documentation of architecture. This technique was developed at the site of Nim Li Punit, Belize, in 2018. Excavating architecture involves documenting the pre-excavated building, liberating overburden, documenting all in situ construction (including wall fall, fill stones, and standing architecture), drawing consolidated architecture, and documenting the final state of the post-excavated buildings. The generation of 3D models greatly assisted in all facets of the excavation, documentation, analysis, and consolidation processes. To ensure that our models were accurate, we documented the reprojection error and final model horizontal distortion to assess the quality of the model. We suggest that documenting both forms of error should become standard practice in any discussion of archaeological applications of photogrammetry.

For historic property types such as archaeological sites and historic buildings, data recovery is often the main part of mitigation plans offered by federal agencies with undertakings that will destroy part or all of a cultural resource. In theory, by extracting important information before destruction, we recover some part of a historic resource's cultural value. In some situations, however, data recovery is impossible or otherwise undesirable, and “creative” or off-site mitigation measures are necessary to mitigate adverse effects. In such circumstances, the Washington State Department of Archaeology and Historic Preservation has accepted funding from federal agencies to create, implement, and enhance an online digital information system for cultural resources. This article describes the Washington Information System for Architectural and Archaeological Records Data (WISAARD) and provides an example of a federal agency funding WISAARD development as creative mitigation for the transfer of archaeological sites out of federal ownership. We discuss the benefits of such systems and address how their development meets preservation goals established by the Advisory Council on Historic Preservation.

Archaeologists have long acknowledged the significance of mountains in siting Greek cult. Mountains were where the gods preferred to make contact and there people constructed sanctuaries to inspire intervention. Greece is a land full of mountains, but we lack insight on the ancient Greeks’ view—what visible and topographic characteristics made particular mountains ideal places for worship over others, and whether worshiper preferences ever changed. This article describes a data collection and analysis methodology for landscapes where visualscape was a significant factor in situating culturally significant activities. Using a big-data approach, four geospatial analyses are applied to every cultic place in the Peloponnesian regions of the Argolid and Messenia, spanning 2800–146 BC. The fully described methodology combines a number of experiences—looking out, looking toward, and climbing up—and measures how these change through time. The result is an active historic model of Greek religious landscape, describing how individuals moved, saw, and integrated the built and natural world in different ways. Applied elsewhere, and even on nonreligious locales, this is a replicable mode for treating the natural landscape as an artifact of human decision: as a space impacting the siting of meaningful locales through history.

In the 54 years since passage of the National Historic Preservation Act, more than 56 million ha of land have been surveyed in the United States, and nearly one million cultural resources have been identified and recorded. These efforts have produced hundreds of thousands of project reports, vast collections of data, and a wealth of descriptive information about the past. The accumulated data can be used to generate important new knowledge about the past, with many scientific and management implications, but remain largely untapped. Following current approaches, many resources will be damaged or lost before effective strategies for studying or preserving them can be developed. Synthesis and modeling are needed in creative mitigation efforts to identify which resources to preserve and study and how best to do so with limited time and funding. This article explores the potential for compiling and synthesizing large cultural and environmental datasets within a geographic information system to model the nature and distribution of cultural resources. It is argued that dedicated synthesis and modeling of cultural resource management data will allow development of more effective and proactive research and management strategies, providing lasting benefit to diverse scientific and traditional communities and the public.

Although we, as archaeologists, recognize the value in teaching nonprofessionals about our discipline and the knowledge it generates about the human condition, there are few of these specialists compared to the number of archaeologists practicing today. In this introductory article to the special section titled “Touching the Past to Learn the Past,” we suggest that, because of our unique training as anthropologists and archaeologists, each of us has the potential to contribute to public archaeology education. By remembering our archaeological theory, such as social memory, we can use the artifacts we engage with on a daily basis to bridge the disconnect between what the public hopes to gain from our interactions and what we want to teach them. In this article, we outline our perspective and present an overview of the other three articles in this section that apply this approach in their educational endeavors.

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.

With an ever-growing range of computational tools and applications now available for archaeological practice, the potential of digital archaeology is greater than ever before. Yet, archaeological curricula have not always followed suit, and many archaeologists are not up-to-date with the necessary digital skills. To fill this gap, online tutorials and learning platforms are being developed to familiarize archaeologists and students with the potential of digital media for archaeological research practices. Given the essential pedagogical role of these platforms, their quality is deserving of deeper interrogation. Here, I review three major platforms offering tutorials on digital archaeology: the Programming Historian, Project MERCURY-SIMREC, and the Open Digital Archaeology Textbook. These are evaluated and compared based on their goals, design (intuitiveness, ease of use), accessibility (use of jargon, required prerequisite knowledge, software requirements), scope (target audience, range of skills addressed, targeted level of improvement), and efficiency (whether or not they achieve their intended goals). The review concludes with a road map contextualizing the current state of available resources in light of the wider state of digital archaeology, and it considers pathways toward future development.

Public Archaeology in the Mediterranean Context (#pubarchMED) is a project that focuses on the management of archaeological heritage in the Mediterranean context from the perspective of public archaeology. Ranging from fully public models where preventive archaeology itself is a challenge to mixed models where the outsourcing of this work has been accomplished to a full extent, the variety of solutions is wide and with a common trend: struggle with mitigation and little space for creativity. This article will delve into the range of models that exist in the Mediterranean, exploring the way they approach, first of all, preventive/rescue archaeology, and then, the relationship between archaeology and society in the process. Building on the challenges of an underfunded scheme for an extremely archaeologically rich territory, different solutions have been set in practice—in some cases, under the auspices of competent administrations in the form of public policy—in the endeavor to include public archaeology in the practice, mostly encouraged by professionals as a personal or corporate initiative, and sometimes even consciously avoided. The discussion will offer some ideas for creative mitigation in the different scenarios, built on the comparative study and the broad possibilities to engage stakeholders positively in the process.

Satellite imagery has long been recognized as well suited for the regional and ecological questions of many archaeological surveys. One underexplored aspect of such data is their temporal resolution. It is now possible for areas to be imaged on an almost daily basis, and this resolution offers new opportunities for studying landscapes through remote sensing in parallel with ground-based survey. This article explores the applications of these data for visibility assessment and land-cover change detection in the context of the Sinis Archaeological Project, a regional archaeological survey of west-central Sardinia. We employ imagery provided by Planet, which has a spatial resolution of 3 m, in four spectral bands, and is collected daily. Using Normalized Difference Vegetation Index (NDVI) values calculated for each survey unit, we find that there is a relationship between NDVI values and field-reported visibility in general, though the strength of this correlation differs according to land-cover classes. We also find the data to be effective at tracking short-term changes in field conditions that allow us to differentiate fields of similar land cover and visibility. We consider limitations and potentials of these data and encourage further experimentation and development.

The Public Archaeology Facility's (PAF) Community Archaeology Program (CAP) at Binghamton University began 25 years ago in response to intense community interest in participating in archaeology. Although non-archaeologists have unlimited access to programming and social media about archaeology, there is more limited access to professionally supervised opportunities. PAF developed CAP to provide non-archaeologists with the opportunity to participate in highly supervised archaeological research projects to share in the process of discovery at the “trowel's edge.” CAP recognizes the challenges and critiques of community programs and mitigates these by creating a climate of ethical practice. Our goal is to educate individuals about the presence of a rich and fascinating past in their own communities and create the sweat equity that can result in advocates for preservation. We operate under the principles that the heritage story embedded in an artifact is worthy of our respect and protection, and that an educated public is more likely to support the preservation of this heritage. Making a connection to people through artifacts builds not only a deeper understanding of the past but also an empathy for preservation. In this article, we introduce the program and reflect on the 25-year history of CAP and future directions.

This article discusses recent trends in archaeological and historic preservation practices in Albania that are leading to new and innovative approaches to what is often termed “mitigation.” To understand this in an Albanian context, it is necessary to review the historical, political, and social context that has shaped the stand of this postcommunist society toward its past as well as the role that this context plays in heritage practices today. I argue that the nationalistic approach toward heritage as a key component of “nation building” in the twentieth century still resonates strongly in the current discourse. This review leads to the conclusion that standard mitigation based on avoidance, recovery/excavation, and documentation phases is the most dominant practice. Experience has shown that this is not always effective in the harmonization of conflicting interests. Public-private benefits, definition of values and significance associated with historic properties, and costs of requested mitigations have all made it clear in the last decade that alternative solutions must be found, even within the rigid boundaries of the existing legal framework. The concept of “creative mitigation” is emerging as a logical need in the practice of historic preservation.

The Office of the Wyoming State Archaeologist has as one of its main objectives to actively engage the population of Wyoming in archaeological stewardship. To achieve this goal, in the past five years, we have launched the youth-oriented Summer Ventures program and the adult-oriented Wyoming Avocational Archaeology Training Program. Both programs were inspired by existing programs in other parts of the country and were launched following research and target audience surveys on how to best adapt them to Wyoming. Despite this preliminary research, our in-field experiences over the past few years have shown some patterns that are causing us to rethink both programs. This article discusses these initial in-field testing years, the issues we have encountered, and the ways we are redesigning both programs to better target the appropriate audiences in light of the different lifestyles of populations, particularly those of youths, in a rural state.

The introduction of the smartphone into the private and professional lives of humans has provided a channel to real-time and place-specific information that can enhance (and disturb) day-to-day living. Given such impact, many museums and archaeological exhibitions have chosen to develop digital applications to enhance the visitor experience via accompanying the visitor through the exhibitions. Yet after a decade, these applications still seem understudied and, in practice, very undeveloped. This review aims to shed some light on the possibilities and shortcomings of museum apps. I discuss and critically evaluate the technical efficiency, practical utility, and user experience of the British Museum Guide (Museums Guide Ltd.) and My Visit to the Louvre (Musée du Louvre) applications. These two mobile apps represent the contemporary standard for museum apps, thereby allowing me to generalize about this genre of digital media.

In the United States, deaccessioning is a poorly understood collections management tool. Archaeologists often view deaccessioning with what Robert Sonderman called “primal fear,” and this fear has caused them to overlook the opportunities that deaccessioned artifacts and collections may provide in the area of public archaeology education. Although deaccessioning without checks and balances can be problematic, when done properly and ethically, it offers previously untapped resources to the creation of educational programming, such as teaching trunk programs. This article discusses the process of deaccessioning and suggests that deaccessioned artifacts may be useful as content for teaching trunk programs. We discuss a case study from our own institution, where we implemented a trunk program in 2016 that was largely stocked with material from a deaccession we had performed the previous year. We also offer suggestions for anyone wishing to implement a similar program.

This article presents a case study of the process of developing and implementing mitigation as the result of adverse effects to cultural resources from the drawdown of Lake Cumberland, Kentucky. Signs of a dam failure in early 2007 triggered the U.S. Army Corps of Engineers (Corps) to implement the emergency drawdown. While the drawdown prevented a life safety catastrophe, it created a new erosion zone and exposed archaeological sites to looters. When it became clear that conventional Section 106 procedures to identify and evaluate these endangered archaeological resources were not an option, alternative and creative mitigation became a necessary approach for the Corps to meet its obligations under the National Historic Preservation Act. This article discusses the creative brainstorming among the Corps, Kentucky state historic preservation officer, and tribes that led to three alternative mitigation measures aimed at educational outreach, raising public awareness, and staff training. Furthermore, the article identifies challenges encountered during the implementation of the mitigation measures. Through the presentation of our mitigation journey, we share some of our lessons learned to improve awareness of the challenges and successes one may encounter during the execution of such alternative measures.
