Under the Boards: Archaeological Site Formation Processes at the Commissariat Store, Brisbane

The study of archaeological site formation processes, although routinely undertaken for prehistoric sites, is only carried out in historical archaeology in a limited way. Understanding the processes which formed the archaeological record of a site is an important first step towards developing justifiable inferences about past behavior and past societies regardless of the age of the site. This paper identifies and examines the cultural and non-cultural processes that formed the archaeological record at the Commissariat Store, Brisbane. The history of the site, from its construction in 1829 as part of the Moreton Bay penal settlement to the present, is examined and the expected impacts and processes on the archaeological record are identified. Archaeological evidence from the salvage excavation of the site undertaken in 1978 and 1979 is analyzed to identify the cultural and non-cultural site formation processes. This study identifies the presence of cultural formation processes including discard, loss, abandonment and re-use from an examination of the historical and archaeological evidence. Non-cultural formation processes at work in the site include faunalturbation, floralturbation, flooding, and aquaturbation.     

Discard behavior on domestic historic sites: Evaluation of contexts for the interpretation of household consumption patterns

Consumer behavior has become an important topic in historical archaeology, and patterns of domestic acquisition, use, and discard are often directly expressed in the archaeological record. Consumption patterns are influenced by factors such as household morphology, life cycle, ethnicity, and socioeconomic status, therefore analysis of domestic site formation processes should take these factors into account. The formation processes exhibited on historic domestic sites may be quite complex, but there is a broad range of analytical methods available for examination of these processes.     

Landscape Archaeology and the Medieval Countryside: Settlement and Abandonment in the Nemea Region

This paper examines the processes of settlement and abandonment of the medieval countryside as revealed by archaeological surveys undertaken in southern Greece. The Nemea region, the focus of an intensive archaeological survey, serves as a case study. Early archaeological surveys approached this time period primarily from a historical point of view. Political history provided the textual frame while the archaeological data were expected to “fill in” the gaps of the historical record. In contrast, in the last twenty-five years the second generation of surveys has taken an active interest in the archaeological documentation of the medieval countryside. The settlement trends observed in Nemea are viewed as manifestations of a variety of political, social, and economic processes.     

Understanding Abandonments in the North American Southwest

The North American Southwest is renowned for its rich archaeological record. Thousands of prehistoric houses and ceremonial centers remain partially standing or form mounds that mark prehistoric villages that were once actively occupied and remain important to the descendants. The visibility of archaeological remains has sparked interest in questions of abandonment among archaeologists and the lay public. We explore reasons for this interest, how it is manifest in archaeological research, and how perception of that research influences popular views of the past and of native people. Our focus is on explanations for the causes of site and regional abandonment as well as on explications of the processes by which abandonments occur. Essential to our perspective is the view that abandonment is a process that involves decisions to move, which may be promoted by dire circumstances, but which are most often settlement strategies. The process of moving requires economic, social, and political decisions about the places from which people move and to which they move.     

Discovery of Ancient Harbour Structures in Calabria, Italy, and Implications for the Interpretation of Nearby Sites

During underwater survey around Crotone, Calabria, Italy, in 2005, structures from two harbour phases were located, possibly dating from the Archaic Greek and Roman periods. Both harbours are close to the Greek and Roman architectural remains on Capo Colonna, as well as to underwater deposits of large stone blocks and other, previously-excavated sites. With the discovery of these harbour structures, new hypotheses arise for understanding the building-material deposits and excavated sites. A critical component of these hypotheses is the assessment of local geological data, specifically ancient sea-level, in relation to the archaeological record.

Site formation processes in caves: The Holocene sediments of the Haua Fteah,Cyrenaica, Libya

Caves have yielded some of the most globally important archaeological sequences, but often their interpretation has suffered from assumptions about cave sedimentary processes. Caves contain distinctive sedimentary environments: this has major implications for the understanding of contained archaeological materials. This paper describes and analyses the Holocene sediments in the Haua Fteah, a sequence regarded as essentially continuous by the original excavator. 50 years after it was first excavated, the Haua's Epipalaeolithic to post-Classical chronological range and rich finds make it still the key Holocene archaeological site in North Africa. The reassessment shows, however, that the sequence is strongly discontinuous and this has major implications for the reinterpretation of the site, as the highly-resolved archaeological record is thus likely to reflect a series of brief occupations, rather than continuous human activity. As with many caves, the sedimentary record in the Haua Fteah is an extremely sensitive indicator of environments and processes in the wider landscape. Secure understanding of sedimentary process, from analysis of the highly individual records found in caves, is essential for full understanding of their contained archaeology.     

Canine Digging Behavior and Archaeological Implications

Abstract

Pit features, frequently reported at archaeological sites, are usually thought be culturally produced. The numbers and forms of pits found at an archaeological site influence inferences of human activity; therefore, the inferred cultural origin of pits at archaeological sites needs to be demonstrated, rather than assumed. Ethnoarchaeological study of dog digging behavior, combined with our understanding of the long symbiotic relationship between human beings and canines, suggests that canine disturbance may be a significant factor in site formation processes. Canines are the probable agent for certain commonly reported pit forms, and are probably implicated in the disturbance of human-dug pits much more often than commonly understood. Dogs dig under a variety of conditions, including those expected in hunter-gatherer, pastoral, and agricultural sites. Excavation of recent dog-holes reveals marked similarities with certain features reported in the archaeological literature.     

An evaluation of the site specificity of soil elemental signatures for identifying and interpreting former functional areas

Soil multi-element analysis is now a routine technique employed to help answer questions about space use and function in and around archaeological sites. The pattern of enhancement of certain elements, including P, Pb, Ca, Zn, and Cu, has been shown by numerous studies to correlate closely with the archaeological and historical record. Interpretation of these soil signatures, however, has generally been more problematic. One approach to the problem has been the use of ethnographic or “known” sites to guide interpretation, but how confidently can results from one site be extrapolated to another? This study of abandoned farms tests the site specificity of soil multi-element signatures of past space use through the use of discriminant models. Data analysis suggests that one to one comparisons of similar sites are much less accurate (38% accuracy) than comparisons based on a wider range of sites (59.3% accuracy), even when the latter have contrasting geology. The results highlight the importance of individual anthropogenic practices during occupation and abandonment in the development of diagnostic soil geochemical signatures.     

Using event-history analysis to examine the causes of semi-sedentism among shifting cultivators: a case study of the Haudenosaunee,AD 1500–1700

Event-history analysis is often used in the social sciences to study the occurrence of particular events over the lifespan of individuals and the impact of various factors on the rate at which those events occur. Like individuals, settlements can be analyzed and important events, such as founding or abandonment, can be studied using this method. Thus, as Richard Paine (1992) has noted, the technique can be useful in archaeological investigations of settlement processes. In this research we use it to explore the causes of settlement abandonment among a temperate shifting cultivators in an attempt to better understand the ecology of this adaptation and in order to evaluate the merits of the method. The sixteenth- and seventeenth-century Haudenosaunee (Iroquois) of northeastern North America present an interesting case study for applying event-history analysis to archaeological settlement dynamics because of the wealth of archaeological settlement data and detailed historic record that allows us to parse out historical factors and analyze the remaining ecological factors. We use event-history analysis as an alternative means for evaluating the relative and absolute effects of several variables that may have been predictive of the lifespan of settlements and the timing of their removal. The results suggest that the decision to move from a village was a complex process in which the population size of a village may have been the single most important, but not the only, determinant of settlement duration.     

Redressing the balance — an archaeological evaluation of North Yorkshire's coastal alum industry

Abstract

Recent acquisitions of coastline by the National Trust in North Yorkshire and Cleveland have included important archaeological evidence of North Yorkshire's former alum industry. Owing to its remote marginal location this evidence has been little studied and there has previously been a bias towards the study of documentary sources as a means of understanding the alum industry. The archaeology of the alum industry is seriously threatened by relentless coastal erosion and there is an urgent need to record this evidence and thus redress this imbalance. The Yorkshire Region of the National Trust owns the partial remains of three important alum sites and the results of the detailed archaeological evaluation of these sites are presented. The archaeological implications of the Trust's continuing acquisition of threatened coastline are also considered.     

Beached Shipwrecks from Channel Islands National Park,California

Abstract

Three shipwreck sites of the 19th century in Channel Islands National Park, California form case studies in evaluating the contribution of beached shipwrecks to maritime and historical archaeology. Two of the sites are consistent with the historically-documented Pacific coast lumber schooners J. M. Colman and Dora Bluhm, but the archaeological record is sparse. Material remains are compared to primary documents, such as original 19th-century construction contracts and insurance classifications, to make a case for the beached shipwreck scatters belonging to these ships. A third site, Comet, presents the other end of the spectrum; its remains have been conclusively identified by historical photographs and the site is a partially-intact hull embedded in the beach sand. This site was also recorded in detail and the formation processes of all three sites were examined to aid in archaeological interpretation.     

The black layer of Middle Palaeolithic combustion structures. Interpretation and archaeostratigraphic implications

Certain aspects of the formation processes of simple, flat archaeological combustion structures such as those present in the Middle Palaeolithic record remain unexplained. Such kind of combustion structures are commonly affected by postdepositional agents and often, their only distinct, well preserved component is a thin black lens on the ground. Hence, understanding the nature of this black lens is essential towards archaeological interpretation. From an interdisciplinary microstratigraphic approach, we present a case study in which for an entire experimental series of flat combustion structures the black layer represents the fire-altered topsoil on which the fire was made. Parallel analysis of archaeological Middle Palaeolithic combustion structures from the site of El Salt (Alicante, Spain) reveal similar patterns, leading to significant implications for archaeological interpretation. In the light of these results, special attention must be paid to the formation processes of flat Middle Palaeolithic combustion features, as black layers and the material contained in them are not necessarily linked with combustion but with preceding activities or events. In such cases, black layers represent intact remnants of occupation surfaces, concealing significant behavioural and palaeoenvironmental information relevant to the reconstruction of Middle Palaeolithic societies.     

Putting the Spotlight on Small Metal Age Pottery Scatters in Northern Calabria (Italy)

This paper presents the results of an in-depth multidisciplinary restudy of small Metal Age surface scatters recorded in earlier fieldwalking surveys in northern Calabria (Italy). Guided by a stratified sampling approach based on site types and topographic positions, high-resolution surface collections at the selected sites were combined with geophysical surveys, test pits, and soil studies to investigate both archaeological deposits and the site formation processes that have an effect on their detectability. This approach is shown to result in a better definition of archaeological ‘sites’, and to help fill in details of regional exploitation and settlement dynamics at the landscape scale. At this broader scale we are also able to model post-depositional processes and slope dynamics affecting the preservation of the archaeological record. With regard to methodology, our study has enabled the evaluation of diverse archaeological detection methods and the fine-tuning of field strategies for the study of Metal Age remains.     

A Test of Ideal Free Distribution Predictions Using Targeted Survey and Excavation on California’s Northern Channel Islands

Using targeted survey, excavation, and radiocarbon dating, we assess the extent to which human settlement patterns on California’s northern Channel Islands fit predictions arising from the ideal free distribution (IFD): (1) people first established and expanded permanent settlements in the regions ranked high for environmental resource suitability; (2) as population grew, they settled in progressively lower ranked habitats; and (3) changes in the archaeological record associated with high population levels such as increases in faunal diversity and evenness in high-ranked habitats are coincident with the expansion to other areas. On Santa Rosa Island, the early permanent settlements were located in both high- and middle-ranked locations, with the most extensive settlement at the highest ranked locations and only isolated sites elsewhere. Settlement at a low-ranked habitat was confined to the late Holocene (after 3600 cal BP). Drought influenced the relative rank of different locations, which is an example of climate adding a temporal dimension to the model that episodically stimulated population movement and habitat abandonment. Because the IFD includes a wide range of cultural and environmental variables, it has the potential to be a central model for guiding archaeological analysis and targeted field research.     

The Middle Palaeolithic of the Nejd,Saudi Arabia

The Pleistocene archaeological record of the Arabian Peninsula is increasingly recognized as being of great importance for resolving some of the major debates in hominin evolutionary studies. Though there has been an acceleration in the rate of fieldwork and discovery of archaeological sites in recent years, little is known about hominin occupations in the Pleistocene over vast areas of Arabia. Here we report on the identification of five new Middle Palaeolithic sites from the Nejd of central Arabia and the southern margins of the Nefud Desert to the north. The importance of these sites centers on their diversity in terms of landscape positions, raw materials used for lithic manufacture, and core reduction methods. Our findings indicate multiple hominin dispersals into Arabia and complex subsequent patterns of behavior and demography.     

Time-Averaging Slows Down Rates of Change in the Archaeological Record

Measuring the pace of cultural change, and understanding its determinants is a fundamental goal of anthropological research. The archaeological record is the main source of information about the pace of cultural change, but it is an imperfect one, as taphonomic loss and mixing distort rate measurements. Here, I focus on the impact of time-averaging on rate measurements. Time-averaging arises when archaeological materials associated with activities and events that took place at different points in time are mixed into the same unit, whether because of depositional processes, disturbance factors, or because archaeologists lump together archaeological contexts when creating analytical units. I use analytical models to show how time-averaging can slow down the observed rates of change under two general modes of cultural change: random drift and directional change. I test this prediction using empirical rates of change from the archaeological record of North America. I show that empirical rates of change are indeed inversely correlated with the duration of time-averaging and provide a range estimate for this correlation.     

Investigating absence: Assessing the cumulative effects of casual collecting at a 19th century Bahamian plantation

Abstract

Recent archaeological work at Prospect Hill, a 19th century plantation in the Bahamas, revealed artifact patterns that are inconsistent with expectations for a plantation site. The quantity and quality of artifacts in residential areas associated with the planter family and the enslaved population were inverted and suggest significant post abandonment changes. The site of Prospect Hill has been a destination for tourists and student groups since the mid-20th century, and the areas of the site most accessible to these visitors are also those with surprisingly low artifact counts. I investigated the possibility that regular visitation involved casual collecting using historical data as well as artifact assemblages from archaeological work at Prospect Hill. My analysis suggests that the archaeological record has been altered significantly through casual, opportunistic collecting, and it offers insights for identifying casual collecting elsewhere.     

‘Well,Sextus, what can we do with this?’ The disposal and use of insect-infested grain in Roman Britain

Abstract

Beetle (Coleoptera) pests of stored products such as the granary weevil may have entered the archaeological record by various routes, including: (1) deliberate dumping, and usually burial, of spoilt grain with the aim of preventing further infestation of grain in storage; (2) the use of infested grain as human and animal food; (3) the incorporation of infested grain and living or dead grain pests into deposits by accident and by reworking. It is suggested that these routes, although outlined specifically for beetle grain pests, can stand as a model for the way other insects and biological remains became incorporated into the archaeological record. It also is suggested that the identification of these different depositional routes depends strongly on taking a multi-proxy (‘indicator group’ or ‘indicator package’) approach to the archaeological and biological record of urban sites.     

Fire Events,Violence and Abandonment Scenarios in the Ancient Andes: The Final Stage of the Aguada Culture in the Ambato Valley,Northwest Argentina

Understanding how archaeological sites are abandoned is a vital part of archaeology. This paper explores abandonment as a phenomenon in a worldwide context, particularly in relation to sites with evidence of fire, and with a special focus on the South-Central Andes. I evaluate the patterns from an area of the Argentinian Andes and discuss the disappearance of the Aguada Culture, one of the central cultures in Argentinian prehistory, using evidence from the core area the Ambato Valley. I conclude that environmental factors were not the sole or determining source of stress, but rather part of a social–environmental dimension in which several factors combined to push a society into a vulnerable situation. In terms of the abandonment of the Aguada settlements in the Ambato Valley, the study shows that frequent forest fires might have played a role, but based upon the regularity of such events as seen in the sediment history, it is unlikely that these were the only factor in the process of abandonment of the valley.     

Contexts for Conflict: Conceptual Tools for Interpreting Archaeological Reflections of Warfare

Abstract

There has been a long history of interest in the material remains of conflict, but in the last two and a half decades archaeologists have made strides in the study of war and warfare. Techniques have been developed, refined, and borrowed to expose the material record of combat. Sites associated with other military undertakings have been discovered and the material culture of conflict has been documented. This growth has expanded an understanding of past conflicts and challenged previously held ideas about warfare. Although archaeologists do not currently have interpretive frameworks to link the diverse sites and objects that form the archaeological record of war, modern military planners have developed such models. This paper uses sites from the North American Great Plains to suggest that military models of conflict analysis can contribute to a synthetic archaeological interpretation of conflict.
