Archaeological magnetometry in an Arctic setting: a case study from Maguse Lake,Nunavut

Magnetometry has been little used on Arctic archaeological sites, but has great potential to help us understand site structure by identifying buried features and providing additional detail about the construction and use of visible surface features. In the Arctic environment, magnetometer surveys have to deal with the effects of permafrost activity on soils and the potential influence of glacial erratics of varying geological composition. Here, we present the results of magnetometer surveys of a non-cultural site with periglacial features and two archaeological sites located in the Canadian low Arctic. Despite considerable “noise” apparently caused by igneous erratics, the surveys successfully identified several frost features and a range of archaeological feature types. They also appear to have located buried archaeological features and identified activity areas within some dwellings. These preliminary results suggest that the technique is worth pursuing on northern sites.     

ARCHAEOGEOPHYSICAL INVESTIGATIONS AT AN EIGHTEENTH-CENTURY CADDO SITE IN NACOGDOCHES COUNTY,EAST TEXAS

Abstract

The J. T. King site (41NA15) is an early-eighteenth-century Caddo habitation site in East Texas. Recent archaeogeophysical work (covering 2.5 ha) at the site has obtained unique data on the spatial organization of a Caddo settlement that was occupied at the time of the Spanish colonization of East Texas. Our interpretation of the magnetometer data is that there are 10 possible Caddo structures in the archaeogeophysical survey area. A few magnetic anomalies have been successfully ground truthed at the J. T. King site. These test excavations have demonstrated a positive correlation between magnetometer anomalies and the occurrence of Caddo architectural features.     

Roman and Byzantine Settlements in the Region of West Irbid

Abstract

It was always clear that for practical reasons any new region-based study of the Roman and Byzantine periods in north-western Jordan would have to rely on existing evidence from archaeological surveys and excavations. The concentration of previous archaeological survey work in parts of the region of West Irbid in Jordan, and especially the surveys made by N. Glueck in the 1940s and S. Mittmann in the 1960s, made this area especially attractive for archaeologists. In this paper, the aim was to analyze the results of the West Irbid survey, particularly of the Roman and Byzantine periods, made during September 2005. The information gathered was of great help, enabling the classifi cation of sites into groups according to the nature of occupation, and analyzing the discovered architectural remains to provide a broader context for interpretation of the nature of Roman and Byzantine settlements in the surveyed region.     

RADIOCARBON TRENDS AND THE EAST TEXAS CADDO TRADITION (CA. A.D. 800–1680)

Abstract

Through the employment of radiocarbon (¹⁴C) dates as data, we use the date combination process to refine site-specific summed probability distributions for 555 dates from Caddo sites (n = 19) in East Texas with 10 or more ¹⁴C dates. Summed probability distributions are then contrasted across river basins and natural regions with the remainder of the East Texas Caddo Radiocarbon Database (n = 338 dates from 132 other Caddo sites), highlighting the temporal and spatial character of Caddo archaeological sites throughout East Texas.     

Protecting a ‘Homeric landscape’: The making of the Butrint National Park,Albania

Abstract

This paper will present research on the vulnerability mapping of coastal archaeological sites currently being undertaken in Northern Ireland. The ultimate aim of this research is improve current predictions of where archaeological sites and landscapes will be at risk in the future from coastal erosion. The initial stage of this approach uses a suite of oblique aerial photographs to construct a baseline of eroding locations and coastal geomorphology. The erosion baseline can then be integrated with existing historic environment records to obtain a coarse first-pass archaeological vulnerability assessment. Subsequent stages can then use this assessment to prioritize future mitigation such as field surveys or monitoring exercises, or conduct further refinements of vulnerability classifications by incorporating information on site type and positioning on a local scale.     

In the Land of Olmec Archaeology

Abstract

Michael D. Coe and Richard A. Diehl, In the Land of the Olmec, two volumes plus maps. Volume I, The Archaeology of San Lorenzo Tenochtitlan, 416 pp.; Volume II, The People of the River, 198 pp. The University of Texas Press, Austin, Texas 1980. 100.00.

The recent publication of a comprehensive report describing the excavations at San Lorenzo, Tabasco, Mexico, In the Land of the Olmec by Michael D. Coe and Richard A. Diehl, provides a significant contribution to Mesoamerican archaeology and a suitable opportunity to review the present status of Olmec studies. The development of Olmec archaeology is a relatively recent phenomenon, with the modern era of research beginning with Matthew Stirling's surveys and excavations at several sites in Mexico's Gulf Coast region (1938–1946), and continuing with the University of California at Berkeley's excavations at the site of La Venta in the mid-1950s. The report by Coe and Diehl of the San Lorenzo investigations (1966–1968) adds considerably to our understanding of the origins and other aspects of Olmec civilization. These contributions, together with several continuing gaps in our knowledge, are reviewed by a resume of Olmec chronology, archaeological remains, external connections, and the implications of the Olmec for the evolution of Mesoamerican civilization.     

PAPERS ON GEOPHYSICAL INVESTIGATIONS OF WOODLAND AND CADDO SITES IN THE CADDO AREA OF THE SOUTHEASTERN UNITED STATES

Abstract

Geophysical investigations on archaeological sites in the Caddo area of the Southeastern United States have become in recent years a critical part of the investigation of prehistoric and early historic Caddo sites, from small farmsteads and hamlets to large mound centers. The various articles gathered here provide substantive examples of the range of geophysical research that has been undertaken on Woodland and Caddo sites in southwestern Arkansas, eastern Oklahoma, and East Texas, and how that research has led to a better understanding of the spatial structure and internal organization of habitation sites and mound centers.     

Archaeology in Megalopolis: Updated Assessment

Abstract

Because of the “disturbed” nature of the terrain, archaeologists working in builtup “urban” situations frequently underestimate the possibilities for the survival of useful archaeological information. Recent experience, most of it in connection with federally-mandated historic resource surveys, has demonstrated that such disturbances are often quite superficial, and that important sites and features may exist, intact, beneath them. In fact, since all human activity disturbs the locale in which it occurs, the evidence of past construction and destruction may be the very resource that gives an area its historical and cultural importance. This paper presents examples of successful recovery of archaeological data in urban contexts in the northeastern United States, and discusses some as yet unsolved problems associated with this relatively new field of archaeological endeavor.     

Early Copper Age Settlements in the Körös Region of the Great Hungarian Plain

Abstract

This article discusses research carried out by the Körös Regional Archaeological Project from 2000 to 2006 at Early Copper Age Tiszapolgár Culture sites on the Great Hungarian Plain. To build a model of social organization for the period, we incorporated information from regional geomorphological studies, soil chemistry analysis, archaeological surface surveys, remote sensing, and systematic excavations at Early Copper Age sites in the Körös Valley of southeastern Hungary. Previous models characterized the transition from the Neolithic period to the Copper Age as an abrupt shift from a tell-based, sedentary, agricultural lifeway to one based on mobile cattle herding. By studying the transition between these periods on multiple geographic and temporal scales, we have identified a more gradual process with widespread regional variation in cultural patterns. Similar social processes characterize the transition between chronological periods and cultural phases in other parts of the world, and we suggest that a multiscalar approach is effective for building comparative archaeological models of long-term social change.     

A Predictive Map of Compression- Sensitivity of the Dutch Archaeological Soil Archive

Abstract

Weak soils like unconsolidated clay and peat may deform and compress considerably by loading, for example, by sand bodies for roads and railways. Archaeological sites within such easily compressible soil layers may therefore be heavily affected by different kinds of construction works. The vulnerability of archaeological sites to compression is largely dependent on soil properties like lithology, grain-size, and previous loading history. This may therefore differ considerably. Predicting the compression sensitivity is of great value for planners, since they can estimate in which areas in situ protection of archaeological sites may be feasible and where it would require (costly) technical measures or plan adaptations.

As part of the Cultural Heritage Agency’s research programme on construction and archaeology, we prepared predictive maps of the compression sensitivity of the subsurface sediments in the Netherlands for 1 m depth intervals from 0 to 20 m depth.

The maps were constructed using a full 3-D model of the subsurface of the Netherlands.

In combination with the Indicative Map of Archaeological Values (IKAW) that is already available, these maps can be used to better estimate the technical measures needed and costs involved for in situ protection of archaeological sites in the planning phase of construction projects.     

Seismic Refraction at Ancestral Puebloan Sites on the Pajarito Plateau,New Mexico

Abstract

Geophysical techniques can be used for non-invasive surveys at archaeological sites. One under-utilized technique, seismic refraction, has many potential applications. It is an inexpensive, efficient way to characterize subsurface deposits, especially at sites with shallow accumulations over bedrock. Archaeologists and geophysicists participating in the Summer of Applied Geophysics Experience from Los Alamos National Laboratory and Bandelier National Monument on the Pajarito Plateau in northern New Mexico characterized Ancestral Puebloan sites (A.D. 1200–1450) using this technique. We provide an overview of how seismic refraction works and demonstrate the applicability of seismic refraction for identifying buried archaeological features such as communal structures and walls.     

Radiocarbon Dating and the George C. Davis Site,Texas

Abstract

Seventy-nine radiocarbon samples were assayed from the George C. Davis Site, a prehistoric Caddoan settlement in the central portion of east Texas. Statistical analysis of the dates convincingly establishes the age of the site as extending from about 780 A.C. to 1260 A.C. and enables us to place the cultural remains into three temporal periods. These dates also provide specific and useful examples for improving the application of radiocarbon dating to archaeological problems.     

Citizen and Monument. The Case of the Greek Island of Naxos

Abstract

Naxos, the largest island of the Cyclades in the Aegean Sea in Greece, has been continuously inhabited from Neolithic times to the present and is full of architectural remains from all historical periods. Traditional settlements, castles, towers, numerous Byzantine and post-Byzantine churches, and several archaeological sites testify to its long and significant history.

The relationship between inhabitants and their archaeological heritage is multifaceted and of special interest. This article analyses the history of this relationship, the reasons that shaped its quality, the problems, and perspectives. It also explores the ways in which citizens, in this particular case the Naxians, participate in the protection of their monuments at a time when tourist development dominates the Naxian economy.     

Bioturbation of Submerged Sites by the Asiatic Clam: A Case Study from Amistad Reservoir SW Texas

Abstract

Burrowing clams represent a poorly studied threat to shallowly buried and submerged archaeological sites across North America. Test excavations at a formerly submerged prehistoric terrace site in SW Texas unearthed burrowing clams (Asiatic clam Corbicula fluminea) in, under; and around features. A review of this clam's ecology, burrowing habits, geographical distribution, and presence in this and other archacological sites illustrates the potential for significant sediment disturbances.     

Finding Mid-19th Century Native Settlements: Cartographic and Archaeological Evidence from Central California

Historical maps have the potential to aid archaeological investigations into the persistence of Native American settlements during the mid-19th century, a time when many Native communities disappear from archaeological view. Focusing on Tomales Bay in central California, we evaluate the usefulness of historical maps as a way to discover and interpret archaeological deposits dating to the period, with the aim of better understanding indigenous patterns of residence at the transition from missionary to settler colonialism. In particular, we focus on diseños and plats created to document Mexican-era land grants as well as early maps produced by the General Land Office and United States Coast Survey. Although we note inconsistencies regarding the inclusion of indigenous settlements on historical maps, our case study offers an example of how archaeologists can employ historical maps and targeted archaeological ground-truthing to discover sites that are poorly represented in the historical and archaeological records.

Reviews

Abstract

The existence of sacred places is a widespread phenomenon throughout Palestine, one which is reflected in various types of local sites, such as water sources, graves, caves, trees and constructed shrines (maqams). In Islamic Palestine, the construction of maqams originated with the Fatimid (a Shiite group), in order to memorialise and 'greet' distinguished figures descended from the family of the prophet Muhammad. Thereafter, the Sunni faith actively adopted this concept and dedicated more than 2,500 sites to prophets, holy people, the righteous and martyrs. The sacred place of Sheikh Shihab ed-Din, like several hundred other Islamic maqams throughout Mandate Palestine, is located on top of a natural hill commanding a panoramic view. This place has held religious importance during the Byzantine and Ayyubid-Mamluk periods, right through to the present day. This paper studies the construction of the maqam as well as its related archaeological remains. It is based on a field study, a survey of the literature, and archaeological explorations conducted during a brief excavation season.     

The Archaeological Field Staff: The Architect

Abstract

In the following article is discussed the archaeological need of the field architect, the work and responsibilities that he undertakes on an excavation, the training that he ideally should have to become an archaeological architect, and the contributions that he can make to the knowledge of ancient architecture.

As well as the advisory help that he can give, the prime role of an architect, from the point of view of the director of an excavation, is that of making accurate surveys and clear and comprehensible drawings. The more conscientious he is and the more experience he has had, the more valuable the architect will be on a dig. This article sets forth various procedures for surveying and measuring and also gives a brief account of the instruments and tools needed for performing these operations. Mention is also made of the different types of drawings that are usually required, starting with the actual state plan and cross-sections and terminating with the completely restored plans, elevations, and perspectives.

For the architect who has the time, training, and initiative, there is also the opportunity of doing individual scholarly work. As pointed out herein, the study and definitive publications of ancient monuments, which only he can successfully conclude, contribute greatly to the archaeological field of knowledge.     

POTENTIAL MAGNETIC SUSCEPTIBILITY AND FRACTIONAL CONVERSION STUDIES OF ARCHAEOLOGICAL SOILS AND SEDIMENTS*

Potential magnetic susceptibility (χ_MAX) and, hence, fractional conversion (χ_CONV) are shown to be critical in interpreting low‐frequency mass‐specific magnetic susceptibility (χ_LF) data. Results presented from 29 sites in the UK and one in Hungary encompass six types of investigation: Quaternary sedimentary stratigraphies, archaeological contexts, surveys of old ground surfaces, topsoil surveys of lithic scatter sites, topsoil prospection surveys and ‘natural’ topsoils. The findings highlight the wide range of χ_MAX values that may be encountered; identify factors affecting χ_MAX; demonstrate that χ_CONV provides a measure of enhancement resulting from burning; and identify environments in which χ_LF analysis is likely to be problematic.     

Archaeology and in situ Preservation in Canton Thurgau,Switzerland

Canton Thurgau (approximately 1000 km²) is situated in the north-east of Switzerland. Its diverse landscape is notable for its hills, the Thur Valley, and Lake Constance. The Archaeology Department of Canton Thurgau is responsible for its archaeology. The archaeological map is quite complete and has over one thousand sites, ranging from the Palaeolithic to post-medieval periods. Particularly remarkable are the prehistoric lakeside dwellings (among them, four UNESCO World Heritage Sites) and the Roman sites, some of which have extraordinarily good conditions for preservation. The vicus Tasgetium (Eschenz) has produced one of the largest collections of Roman wooden objects and features found anywhere in the world. The Archaeology Department of Canton Thurgau conducts field surveys, excavations and scientific research. Its collections and archive are also of great importance. A major goal is to preserve the numerous sites of the canton in situ. In sensitive shore areas, where erosion (wave action, shipping etc.) threatens the exposed prehistoric cultural layers of the pile dwellings, measures are being taken to cover the areas and keep destruction at bay. These interventions are accompanied by monitoring. But numerous Roman and medieval ruins have also been restored according to the latest standards and thus prevented from gradual destruction. Thanks to zoning plans and a close working relationship with the local authorities, timely intervention can take place when sites are threatened. The results of the archaeological research are conveyed to the public and professional circles through the Museum for Archaeology and by way of popular and subject-specific publications.
