Assessing the Stability and Sustainability of Rock Art Sites: Insight from Southwestern Arizona

In light of global trends in human population growth and urbanization, burgeoning cultural heritage tourism industries, and climate change, cultural heritage places in nearly every corner of the world are significantly threatened, and will remain so into the foreseeable future. Rock art sites are some of the most imperiled, with their exposed contexts posing unique challenges to conservation. Consequently, effective management of publically accessible rock art sites necessitates a sustainable approach that weighs visitation in regard to cultural significance and site stability. This essay integrates rock art stability and sustainability assessment methodologies at the Painted Rock Petroglyph Site in southwestern Arizona. The study specifically applies the Rock Art Stability Index (RASI) to evaluate the natural and anthropogenic weathering forces impacting the site, and the Heritage Asset Sensitivity Gauge (HASG) to assess site sustainability under existing management practices in relation to current and forecasted rates of visitation. A spatial analysis of aggregated RASI data shows that visitor foot traffic has had some of the most profound impacts to the petroglyphs. Unrestricted access to the site area is also highly correlated with the presence and location of vandalism and graffiti, and visitor-related trampling has adversely affected the site’s surface artifact assemblage. Application of the HASG projects that, while existing management practices are fairly sustainable, they become less so under forecasted increases in visitation. Further, the HASG appraises the site’s cultural significance as outweighing its market appeal, indicating management efforts should prioritize conservation over tourism-related development.     

Toy Story: Homophily,Transmission and the Use of Simple Simulation Models for Assessing Variability in the Archaeological Record

The interpretation of spatial and temporal patterns in the archaeological record remains a long-standing issue in the discipline. Amongst many methods and interpretations, modelling of ‘biased transmission’ has proved a successful strategy to tackle this problem. Here, we investigate a type of biased transmission, homophily, that is the tendency of individuals to associate and bond with similar others. In contrast to other social sciences, homophily remains underused in archaeology. In order to fill this gap, we develop six distinct variants of a well-established modelling framework borrowed from social science, Axelrod’s Cultural Dissemination Model. These so-called toy models are abstract models used for theory-building and aim at exploring the interplay between homophily and various factors (e.g. addition of spatial features such as mountains and coastlines, diffusion of innovations and population spread). The relevance and implications of each ‘toy model’ for archaeological reasoning are then discussed.     

Sequential Incisions on a Cave Bear Bone from the Middle Paleolithic of Pešturina Cave,Serbia

We present the detailed analysis of a cervical vertebra from a cave bear, found at Pe?turina cave, Serbia, in a Mousterian archaeological level dated by radiocarbon at 43.5–44.6 kyr cal BP, and by ESR to between 93.5 and 102.5 kyr BP. Identified as a portion of the cranial articular facet, the fragment displays ten subparallel grooves. The microscopic study of these grooves and other surface modification present on the bone fragment, conducted with multifocus optical and confocal microscopes and complemented by a taphonomic analysis of the associated faunal assemblage, supports the hypothesis that the incisions were made by humans. Results are used to critically examine ambiguities implicit in the analysis and interpretation of early engravings, a category of material culture that has been playing a key role in the identification of early instances of symbolically mediated behavior.     

Parental Grief and Mourning in the Ancient Andes

Parental grief is an intense emotion shaped and mediated by cultural attitudes toward death, the strength of parent-child attachment, the age of the deceased child, and the role of children in society. Despite some assertions that high infant mortality or economic hardship may lessen parental grief, cross-cultural studies show that child death often causes emotional distress to parents, in particular mothers. Funerary treatments of children, especially infants, are often simplified, contradicting more immediate and immaterial expressions of parental grief that cannot be studied archaeologically. In this study, I examine the funerary treatment of children in ancient Andean Tiwanaku society (A.D. 500–1100). I assess the use of ritual practices and objects associated with children’s burials as indicative of children’s social identities and parental mourning. The nature of grave assemblages in regard to different ages of the children suggests that parental attitudes toward their children changed over the course of childhood. The choice of offerings seems to reflect parental attachment to and recognition of the child’s life. Modifications of ceramic vessels point to the intimate mourning gestures of grieving mothers who sought to provide their deceased children with the necessary offerings to assume their place among the community of venerated ancestors. This study draws on ethnographic, psychological, and ethnohistoric sources of parent-child bonds in the Andes and beyond to investigate children’s burials not merely as reflective of childhood and children’s role in society but as the material record of parental attachment and emotion in the past.     

Integration of Complementary Archaeological Prospection Data from a Late Iron Age Settlement at Vesterager—Denmark

The complementary use of various archaeological prospection data sets offers a series of new possibilities for the investigation of prehistoric settlements. In addition to the separate interpretations of the single methods, the implementation of image fusion provides an additional tool to obtain an even higher degree of data integration during the interpretation process. To investigate some possibilities and risks of image fusion, a procedure frequently used in the medical field but rarely applied in archaeology, various algorithms inside a dedicated MATLAB toolbox TAIFU (Toolbox for Archaeological Image FUsion) were tested on the geophysical prospection data from an Iron Age settlement near Vesterager in West Jutland, Denmark. The Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology had conducted large-scale, high-resolution ground-penetrating radar (GPR) and magnetometry surveys at the site in 2014, based on its discovery by the Ringkøbing Museum through aerial photos and the results of a follow-up excavation in 2009. The aim was to determine if, and to what extent, geophysical prospection together with a novel integrative interpretational approach was able to add more detailed information to an already known prehistoric settlement. Results yielded a variety of deeper insights into the separate farms (dated to around AD 400), including the discovery of several new structures and more information about the construction of the longhouses, as well as a first suggestion on how to implement image fusion into the process of analysis and archaeological interpretation of geophysical data sets.     

Refining the <Emphasis Type="Italic">Maritime Foundations of Andean Civilization</Emphasis>: How Plant Fiber Technology Drove Social Complexity During the Preceramic Period

Moseley’s (1975) Maritime Foundations of Andean Civilization hypothesis challenges, in one of humanity’s few pristine hearths of civilization, the axiom that agriculture is necessary for the rise of complex societies. We revisit that hypothesis by setting new findings from La Yerba II (7571–6674 Cal bp) and III (6485–5893 Cal bp), Río Ica estuary, alongside the wider archaeological record for the end of the Middle Preceramic Period on the Peruvian coast. The La Yerba record evinces increasing population, sedentism, and “Broad Spectrum Revolution” features, including early horticulture of Phaseolus and Canavalia beans. Yet unlike further north, these changes failed to presage the florescence of monumental civilization during the subsequent Late Preceramic Period. Instead, the south coast saw a profound “archaeological silence.” These contrasting trajectories had little to do with any relative differences in marine resources, but rather to restrictions on the terrestrial resources that determined a society’s capacity to intensify exploitation of those marine resources. We explain this apparent miscarriage of the Maritime Foundations of Andean Civilization (MFAC) hypothesis on the south coast of Peru by proposing more explicit links than hitherto, between the detailed technological aspects of marine exploitation using plant fibers to make fishing nets and the emergence of social complexity on the coast of Peru. Rather than because of any significant advantages in quality, it was the potential for increased quantities of production, inherent in the shift from gathered wild Asclepias bast fibers to cultivated cotton, that inadvertently precipitated revolutionary social change. Thereby refined, the MFAC hypothesis duly emerges more persuasive than ever.     

The Suitability of 3D Data: 3D Digitisation of Human Remains

The use of 3D data in the analysis of skeletal and fossil materials has conveyed numerous advantages in many fields; however, as the availability and use of 3D scanning equipment are rapidly increasing, it is important for researchers to consider whether these methods are suitable for the proposed study. The issue of suitability has been largely overlooked in previous research; for instance, casts and reconstruction methods are frequently used to increase sample sizes, without sufficient assessment of the effect, this may have on the accuracy and reliability of results. Furthermore, the reliability of geometric morphometric methods and the implications of virtual curation have not received sufficient consideration. This paper discusses the suitability of 3D research with regard to the accuracy, reliability, and accessibility of methods and materials, as well as the effects of the current learning environment. Areas where future work will progress 3D research are proposed.

Subsistence Digging in Iran’s Archeology and the Cultural Heritage

Subsistence digging is an action taken by people living a region to find antiquities in order to sell them and use resulting proceeds as a means of living. Subsistence digging is the main source of recent excavated cultural materials supplied to the market. The term is tied to the economy and plays an important socioeconomic role in many countries particularly in developing countries throughout the world by solving the starvation problem. Despite of the frequency of digging activities, they have not been investigated and even are not known in Iran so far. To find out the possible reasons behind digging activities and the neglect of the relevant authorities and agencies, this study explores subsistence digging and distinguishes it from looting, a term that is frequently referred to as the looting of cultural heritage in Iran.
