More and more archaeologists who once relied on shovels and surveys now regularly collect data with digital sensors and use computer-based management systems to carry out complex analyses. Geographic information systems (GIS) and geographic information science (GISc), satellite remote sensing, aerial and close-range photography, terrestrial and aerial Light Detection and Ranging (LiDAR), near-surface geophysics, and a wide array of visualization schemes designed to integrate and display data from multiple platforms are now integral to every stage of archaeological investigation, interpretation, and reporting. Even though these methods are an increasing part of archaeological research worldwide, there have been few conferences, meetings, or workshops dedicated to sharing methods and applications in digital archaeology in North America or even in the Western Hemisphere, with the exception of a few special sessions in regional or general archaeological conferences. This deficit is particularly striking in comparison with the situation in Europe, where several societies dedicated to archaeological geomatics regularly hold both continental and regional meetings.

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.

Three-dimensional (3D) digital scanning of archaeological materials is typically used as a tool for artifact documentation. With the permission of the Caddo Nation of Oklahoma, 3D documentation of Caddo funerary vessels from the Vanderpool site (41SM77) was conducted with the initial goal of ensuring that these data would be publicly available for future research long after the vessels were repatriated. A digital infrastructure was created to archive and disseminate the resultant 3D datasets, ensuring that they would be accessible by both researchers and the general public (CRHR 2014a). However, 3D imagery can be used for much more than documentation. To illustrate this, these data were utilized in a 3D morphometric analysis of the intact and reconstructed vessels to explore the range of variation that occurs in ceramic vessel shape and its potential contribution to the local ceramic taxonomy. Results of the 3D morphometric analysis demonstrate the potential for substantive analytical gains in discussions of temporal resolution and ceramic technological organization in the ancestral Caddo region.

Known in English as Mount Taylor, Dewankwin Kyaba:chu Yalanne (“in the east snow-capped mountain”) in northwestern New Mexico is a sacred landscape to the Zuni people. From an archaeological perspective, the mountain is dotted with hundreds of discrete archaeological sites that record 12,000 years of history. From a Zuni perspective, Mount Taylor is a rich cultural landscape—a tangible record of ancestral migrations, a living being, a pilgrimage site, a referent in religious prayers, a spiritual source of rain, and a collecting place for spring water, animals, minerals, and plants. For Zunis, all of these facets of the mountain combine to create a “total landscape” that is both a source and an instrument of Zuni culture. This article presents a case study of a compliance project to document the potential impacts of a proposed uranium mine at the base of Mount Taylor on Zuni traditional cultural properties. The project demonstrates how archaeologists can benefit from a landscape perspective that builds from the traditional knowledge of descendant communities. The Zuni standpoint further helps shape a CRM practice that is anthropologically informed and consistent with a developing federal mandate to use landscape-scale analysis in heritage management and mitigation practices.

This article discusses the effectiveness of Mexico’s national heritage business model within a context of economic growth, infrastructure development, and structural shifts that pose risks to the preservation of heritage resources. To meet these challenges, the future heritage professional requires a training profile that most archaeology departments in Mexico are unable to accommodate. Recognizing the importance of cultural resources management (CRM) and heritage business and marketing skills, the BA program in Development and Intercultural Management, offered at the Universidad Nacional Autónoma de México, is exploring new ways to create business models to finance heritage preservation. In an emergent economy, many students lack the opportunity to pursue higher education degrees, joining the labor market at a very early stage in their careers, without much knowledge of how to make heritage a lever for economic growth. Thus, a goal of this article is to encourage the early teaching of business and marketing in programs around the world by demonstrating how such training opportunities are opening up unimaginable career avenues for the future heritage professional in Mexico.

Thin-section petrography is a crucial tool for the study of archaeological ceramics, and in recent years, image analysis has emerged as a powerful quantitative enhancement of that tool. Exploratory applications of image analysis to archaeological ceramic thin sections, and related work by sedimentary geologists, have indicated its usefulness to the field. In this paper, we first present the results of experimental work testing the consistency and reproducibility of image analysis. We identify procedures for fast and reliable analysis of thin sections using laboratory-prepared ceramic specimens of simple clay-sand systems. We then show how those procedures can be slightly modified to accommodate more complex archaeological specimens. We conclude with a discussion of the role of image analysis within the overall context of thin-section petrography of ceramic materials, as one among a repertoire of techniques, adding quantitative data and increasing the usefulness of ceramic thin sections for addressing archaeological research questions.

Medium-scale archaeological phenomena (large settlements, landscape features and infrastructural systems, road networks, etc.) pose significant challenges to archaeological documentation. Traditionally, such features are mapped either schematically or via labor-intensive (or otherwise costly) high-resolution methods. The advent of inexpensive, packable unmanned aerial vehicles (UAVs) and lighter-than-air platforms, combined with increasingly sophisticated photogrammetric and mobile geographic information system (GIS) software systems, presents opportunities for improving on these compromises. Here, we present results from test flights and photogrammetric mapping using UAVs and a meteorological balloon, combined with mobile GIS-based attribute registry of architectonic features at a large, complex colonial planned settlement (Mawchu Llacta de Tuti) in highland colonial Peru. First, the operating parameters of UAVs are presented, as well as the imagery capture and photogrammetric processing work flows. Second, we provide an overview of the tablet-based mobile GIS system used to digitize a site plan (based on the imagery from the UAV) and register architectural attributes from each building. The results from initial testing suggest that in the near future, such combined close-range photogrammetry and mobile GIS-based systems will significantly enhance and expedite high-resolution data registry of a wide range of archaeological features, sites, and landscapes.

Data collection takes up much of the already limited time archaeologists have to excavate and often requires additional time to digitize. Moreover, despite efforts to standardize data, archaeologists often find errors such as blank or incorrectly recorded fields. To avoid these issues, several projects have made use of tablet computers to streamline and digitize data, but this process can be opaque, specialized, and expensive. Previous research has addressed neither the general feasibility of developing and utilizing mobile devices for data collection nor the quality and quantity of these data. In this article, I review existing methods and practices for integrating data collection on mobile devices in order to evaluate the costs and feasibility of transitioning to a mobile-based data collection system. Through a case study using OsteoSurvey, a series of bioarchaeological data collection forms for Android tablets, I assess the efficacy of data collection on mobile devices. An experiment comparing OsteoSurvey to traditional paper forms demonstrates that participants saved time and made fewer mistakes using the OsteoSurvey forms, resulting in the collection of 21–32 percent more data. Consequently, data collection with mobile devices can significantly increase the overall productivity and quality of archaeological research

Digital imaging technologies have enhanced archaeological research and profoundly expanded the scale of the discipline’s potentialities. As illustrators and archaeologists move away from using hand-drawn images (of hand-held, real-life objects) to depict artifacts and other archaeological information, certain capabilities of the traditional illustrative process are lost. One such loss is the ability to present a complete and informed representation of an artifact free of the distortions and visual limitations that single-perspective (i.e., digital or photographic) imagery produces. This is accomplished by the illustrator through the unification of multiple views of the artifact from various perspectives into a single two-dimensional image that communicates to the viewer important attributes of the artifact, free of distortion and remaining true to the measured, analytical conventions of the illustrative process. Liberation from the single-viewpoint perspective was one of the fundamental elements of the Cubist movement. Traditional archaeological illustrators utilize Cubist principles to communicate visually to the viewer a complete, accurate, and undistorted package of information about an artifact. The supplanting of hand-drawn illustrations by digital images in today’s archaeological publications threatens to revert the visual representation of data back to uninformed, surficial “snapshots” of incomplete objects.

Archaeologists from the Center for American Archeology (CAA) in Kampsville, Illinois, are engaged in a program to test the potential for ground-penetrating radar (GPR) and electrical resistance tomography (ERT) to effectively document the internal structure of a variety of Middle (ca.2200–1550 B.P.) and Late Woodland (ca.1550–950 B.P.) mounds in the Lower Illinois River Valley (LIV). This project, embedded within ongoing CAA regional research efforts and the Arizona State University Kampsville Field School, demonstrates that both GPR and ERT permit the identification and measurement of significant internal mound structures. Key structural elements can be confidently identified in the geophysical data from the five test mounds, and excavation results can be conclusively linked with results of excavation in mounds that have been tested. This study opens the way for the development of a set of procedures for a regional research initiative in the LIV to understand structural variation between Middle and Late Woodland mounds using ground-based remote sensing methods as a primary source of data and thus minimizing invasive and destructive investigation techniques.

The orientations of European prehistoric structures have been studied independently by landscape archaeologists and archaeoastronomers. Despite their similar interests, the two fields have failed to converge primarily because of their differing epistemologies. This paper argues that archaeology has much to gain by integrating the two fields to provide a fuller and more balanced exploration and understanding of the location and orientation of the European megaliths. It is suggested that prehistoric archaeoastronomy needs to become more grounded on the archaeological record and context of the prehistoric structures it studies. If it is to generate knowledge of value to archaeology it needs to become a “skyscape archaeology.” This paper looks at current archaeoastronomical approaches through the lens of archaeological practice. It identifies some limitations and discusses how landscape archaeology can inform archaeoastronomy on overcoming them. A methodology that attempts this necessary cross-fertilization, by shedding unfounded assumptions and developing a more phenomenological approach to pattern-recognition, is proposed. This methodology is applied to a case study in central Portugal. The emergent narrative, linking a cluster of dolmens to a local mountain range and the star Aldebaran, not only fits the archaeological record, but is mirrored by local folklore, lending further support to the validity of this methodology.

Neutron imaging is a nondestructive application capable of producing two- and three-dimensional maps of archaeological objects’ external and internal structure, properties, and composition. This report presents the recent development of neutron imaging data collection and processing methods at Oak Ridge National Laboratory (ORNL), which have been advanced, in part, by information gathered from the experimental imaging of 25 archaeological objects over the past three years. The dual objectives of these imaging experiments included (1) establishing the first methodological procedures for the neutron imaging of archaeomaterials involving the CG-1D beamline and (2) further illustrating the potential of neutron imaging for archaeologists to use in the reverse engineering of ancient and historical objects. Examples of objects imaged in two and three dimensions are provided to highlight the application’s strengths and limitations for archaeological investigations, especially those that address ancient and historic technologies, materials science, and conservation issues.

While digital games are used for health intervention, language training, and science learning, there are few instances of games being used to teach archaeology. This is a missed opportunity, as narratives of exploration and discovery make archaeology well suited to digital games. This article discusses Red Land/Black Land, a prototype Civilization V mod (modification of an existing game) that allows players to explore both the process of cultural change in ancient Egypt and the construction of archaeological knowledge about ancient Egypt. As a case study of scholarly game design, the article explores the project’s development. Included is a discussion of play mechanics, the merits and process of modding, and the resources required to build games in academic environments. The article also discusses preliminary efforts to test the game in an undergraduate classroom. Ultimately, the article argues that digital games are powerful tools for communicating archaeology. Instead of falling under the glamour of commercial games, however, scholars should adopt cost effective approaches to game design, looking to mobile play, alternate reality games, modding, and browser based games to realize their vision. The article also argues that the actual process of designing a game is an excellent tool to teach archaeology.

While tablet devices are becoming commonplace in archaeological research, the transfer of data for analysis is a matter of critical concern. As geographic information systems (GIS) are increasingly incorporated into our archaeological research, there is a need not only to streamline data acquisition, but also to collect data that can be used in conjunction with high-level spatial analytical tools, such as those available in ESRI’s ArcGIS. During a short lab season, various methods of paper-free data collection and cross-platform transfer using these user-friendly devices were tested. It was found that both iPad and Android-based systems present great advantages in terms of portability and electronic data acquisition. However, file compatibility and transfer of data across multiple platforms present a number of important drawbacks. The present case study focuses on the development of a data collection protocol implemented by the Proyecto de Investigación Arqueológica Zaña Valley (PIAZ), Peru, that moves beyond these limitations. The ultimate incorporation of data collected using tablet devices demonstrates the potential for this tool in archaeological research, along with the pitfalls for projects that rely heavily on GIS. Significant findings regarding the advantages, as well as the limitations, of e-data collection, transfer, and storage are discussed.

Although alternatives have become available, pen and ink drawings of stone tools dominate archaeological publications. Despite the existence of a conventional illustration framework, the work produced by illustrators can be inconsistent and hinges on skill level and time commitment. Discussions going back to the 1880s critically question the use of illustrations for the purpose of scientific publication. Alternatives, such as laser scanning and photogrammetric modeling, are now available for displaying lithics. These alternatives can remove the subjectivity involved in artistic rendering, creating replicable results, regardless of who is collecting the data. In addition to creating more regularized and objective representations, there are a significant number of analytical and other benefits to adopting novel imaging techniques to depict stone tools in publications. A set of three-dimensional (3D) models are presented here to demonstrate the capabilities of laser scanning and, potentially, photogrammetric modeling as replacements for lithic illustration.

In large arid floodplains, like that of southern Iraq, the rise of the water table associated with irrigation can result in surface salt concentrations over the remains of subsurface architecture. These traces are visible only from the air but are sometimes captured by commercially available submeter pixel imagery. This article describes the methods used and some of the results of a project using QuickBird, WorldView-1, and WorldView-2 imagery to investigate settlement systems in southern Mesopotamia dating between the fourth and first millennia B.C. Following a discussion of methods used to better predict which images of which sites will produce the desired results, a brief exploration of key anthropological questions that these data allow us now to ask will be presented.

Archaeological resource protection remains an important management concern on public lands in the U.S. Southwest and beyond. While legislation and educational programs have contributed to a general improvement in public attitudes toward cultural heritage, archaeological resources on public lands remain vulnerable to a variety of human impacts. We present results of a condition and damage assessment of 96 prominent precontact sites on the Tonto National Forest (TNF) in central Arizona. We summarize field methods and observations and discuss their implications for the management and protection of archaeological resources on the TNF and other public lands. Sites at varying distances from roads were assessed in an effort to identify potential relationships between damage frequency and road proximity. Field results indicate that (1) unauthorized damage occurs more frequently at sites near TNF roads; and (2) economical measures like advisory signage provide potentially effective means of deterring unauthorized damage to sites in higher risk locations. Our findings add to a knowledge base important for understanding patterns of damage and site vulnerability and for developing practical protection strategies in line with public land missions and administrative capabilities.

Different types of artifacts and building materials react in varying manners to heat exposure, and the analysis of their degrees and patterns of thermal alterations provide important clues to the intensity of fire to which they were subjected. Such data allow researchers to examine the presence or absence of a building fire, the quantity of fuel, and the intentional or accidental nature of the fire. This approach is particularly important in the tropical lowlands, where evidence of fire in the forms of charcoal and ash may not be well preserved. At the rapidly abandoned site of Aguateca, Guatemala, the amount of charcoal and ash was small, but the examination of numerous artifacts left in situ and of building materials identified clear evidence that many buildings were burned at the time of abandonment. Similar lines of evidence were also found in artifact-poor, gradually abandoned structures at Ceibal, Guatemala. These results suggest the possibility that the burning of structures at the time of abandonment may have been more common in the Maya Lowlands than generally thought.

Remote sensing applications are increasingly common in archaeology but they often focus on high resolution imagery and direct archaeological site detection. Moderate spatial resolution remote sensing instruments, which have (near) daily repeat intervals, but contain less detailed spectral and spatial information, have been employed much less frequently in archaeology. However, moderate remote sensing data offer distinct advantages for archaeological research as they can be used to relate archaeological, ecological, and climactic data at vast spatial scales. To show this potential, we use moderate remote sensing data to examine the impact of landscape heterogeneity on the spread of indigenous maize horticulture in the northern Great Lakes during Late Precontact (ca. AD 1200-1600). Analyzing National Aeronautics and Space Administration (NASA) Moderate Resolution Imaging Spectroradiometer (MODIS) imagery, we identify differences in freeze/thaw cycles across inland lakes in Michigan, showing that some large inland lakes produce a microclimatic amelioration, possibly extending the growing season for prehistoric maize cultivation. Conducting geospatial analyses, we find that burial mounds and maize cultivation practices were associated preferentially with larger inland lakes with microclimates. We could not have found these dynamic interrelationships between microclimates, burial mounds, and maize cultivation if not for both the frequent temporal imaging and large spatial coverage provided by moderate resolution remote sensing imagery.

The majority of terrestrial scanning projects in archaeology have focused on heritage documentation, preservation, and the three-dimensional (3D) reconstruction of prominent sites and objects. While these are very important archaeological foci, not many have used terrestrial scanning methods for prospection and feature analysis, similar to the way many have employed airborne LiDAR. While airborne LiDAR scanning is able to situate and analyze archaeological sites on an expansive scale, the ground-based method also captures and defines any landscape anomalies or depressions from cultural features that have remained invisible to the naked eye due to environmental restrictions. In an attempt to test this recording method, we set out to paint a non-invasive, 3D digitized picture of the ancient Maya site of Pacbitun, Belize, using terrestrial scanning to distinctly detail Pacbitun’s structures, plazas, causeways, and karst features. This paper details the process through which 3D terrestrial scanning was executed at Pacbitun and three associated peripheral caves during the 2012 and 2013 field seasons. We discuss the potential laser scanning has for visual analysis in archaeology and evaluate application difficulties encountered in the field, as well as current data interpretation issues.
