Establishment of conservation,design and construction criteria for protective shelters at Fort Selden State Monument,New Mexico

Abstract

Foit Selden State Monument, located in southern New Mexico, consists of the exposed adobe ruins of a military post that was occupied from 1865 to 1981. A management plan for the site is currently being developed in which an option being considered for preservation is the construction of a protective shelter.

The process of establishing conservation, design and construction criteria for a potential shelter at Fort Selden involves the assessment of technical issues and the evaluation of public support for the criteria and purpose of the monument. The conservation concerns are based upon accepted standards for conservation and construction criteria while the design and construction standards involve a higher degree of Public concern, particularly the public expectations exerted on a historic site in the United States.

The criteria for Fort Selden are currently being codified. This paper outlines the preliminary criteria as well as the process by which these criteria will be established and meshed with the public expectations of the site. The planning process is presented and the underlying philosophies of deciding to shelter, designing the shelter and constructing the shelter. Future evaluations of the shelter's success can be gauged against these original criteria and mindset.     

Evaluation of the protective shelter at Blackwater Draw Archaeological Site,New Mexico

Abstract

Blackwater Draw Archaeological Site is located in Roosevelt County, New Mexico, and is the type site for the Clovis culture which dates back 12,000 years. In 1995 the stakeholders for Blackwater Draw convened a meeting with an expert consultant to evaluate the efficacy of a protective shelter proposal. The purpose of the proposed shelter was to protect palaeo-Indian finds excavated in 1983–4 and displayed in situ. Recommendations were made and, several years later, shelter construction was completed. In 2000, the shelter as built was re-evaluated.     

Methodology,consetvation criteria and performance evaluation for archaeological site shelters

Abstract

The many intersecting issues that arise when deciding whether to shelter an archaeological site should be approached using a values-based methodology, one that has demonstrated its validity arid practical worth in conservation over recent decades. Nonetheless, pitfalls abound in the decision-making process and in establishing effective conservation criteria which should be based principally on a thorough understanding of the threats to the resource and the specific deterioration mechanisms operating, with the objective of creating a shelter that will preserve the site's identified values. An aspect that has received almost no attention in the past is evaluation of a shelter's performance, both qualitative and quantitative, in preserving the site. It is urged that this receive priority when establishing the conservation criteria during the initial phases of a sheltering project. Issues are illustrated from a range of diverse sites, including a number of published shelters. The paper first looks at the examples of the Laetoli (Tanzania) and Lark Quarry (Australia) trackway sites in the context of decision-making and conservation criteria, and then discusses two examples of evaluation: one quantitative, using an experimental shelter and the other discussing publications on a petroglyph site shelter.     

Issues of In Situ Conservation at Jinsha,People’s Republic of China

Abstract

The archaeological site of Jinsha, in Sichuan Province, China, was excavated in 2001, revealing extensive evidence of a substantial 3000 years old settlement. The site was subsequently sheltered and in 2007 an on-site museum was constructed. The shelter’s performance, in terms of environmental control, public interpretation and site management, is assessed. The need for more scientific research on site material science is highlighted.     

The Tenth Conference of the International Committee for the Conservation of Mosaics. Conservation: An Act of Discovery

Abstract

The Herculaneum Conservation Project has approached the conservation of a large-scale archaeological site (Herculaneum, Italy) suffering widespread forms of decay in two different ways: 1) with a site-wide campaign addressing conservation problems in areas most at risk and 2) with a case-study project for one urban block (Insula Orientalis I ) exploring some of the complex conservation challenges in more detail. One of these challenges is how to approach the repair of existing roofing and how to design new forms of protective shelter for those spaces that have never been covered. Short-, mid- and long-term solutions for the repair and substitution of existing roofing are being tested as part of the site-wide campaign, while in the case-study area more enduring solutions (new mid- and long-term) for new shelters are being trialled.     

Preservation In Situ for Tourism: An Early Christian Monastic Complex on Sir Bani Yas Island,Western Abu Dhabi,UAE

Abstract

This paper reports on the conservation measures taken to protect and display the remains of a pre-Islamic Christian monastic complex on Sir Bani Yas Island, Abu Dhabi, UAE, and the reasoning behind the decisions. The excavated areas of the site are now partly sheltered, and partly reburied. Observations are made on the effectiveness of the shelter building, and the reburial system used between 1996 and 2010, and on the measures currently being used to preserve plaster floors and faced standing walls in aggressive environmental conditions. Work has been carried out to ?nd ways to make the site as legible as possible while also conserving it. Methods of site monitoring are also discussed.     

Site conservation during excavation: treatment of masonry,wall plaster and floor mosaic remains of a Byzantine church in Petra,Jordan

Abstract

The conservation treatments carried out between June 1992 and August 1993 on the architectural remains of a Byzantine basilica in Petra, Jordan, during and immediately after the excavation are described. The treatments completed during excavation included: stabilization and consolidation of certain sections of the basilica's sandstone ashlar masonry; cleaning and consolidation of the unpainted lime wall plaster decorating the basilica interior; cleaning and consolidation in situ of the extensive remains of a figurative mosaic pavement in the two side aisles, and the fragmentary remains of the opus sectile pavement in the central aisle. The consolidation treatments included injection grouting using hydraulic mortar mixes produced in Italy, and mortar repairs using slaked lime and hydraulic lime. The existence of the mosaic required preventive conservation measures during the excavation, such as the construction of a temporary shelter over the site during the winter, the use of temporary protective facings over damaged areas of the mosaic, as well as the temporary backfilling of the mosaic with soil over a layer of geotextile in order to protect the mosaic between the initial phase of conservation work and the construction of a permanent shelter for the site in the near future. The importance of having a conservator present on site during the critical phase of excavation, when all materials are most susceptible to damage, is emphasized. The Petra Church Project will hopefully serve as a model for future excavations in that it employed two conservators from the beginning of the excavation: one for small finds, the other responsible for the site and the architectural remains removed from the site during the excavation.     

A botanical approach to the planning of archaeological,parks in Italy

Abstract

The positive role of plants in archaeological areas, as well as the enegative action of their roots in causing structural damage, are summarized in this paper. The traditional approach to the planning of vegetation in Italian archaeological areas is briefly described. A general philosophy for botanical projects in these sites is proposed, taking into account ecological, historical and conservation parameters. The principal aims of the suggested approach are: protection of the naturalistic, historical and landscape features of the existing site, in so far as they are compatible with the archaeological structures; and the introduction of new elements, in keeping with the original landscape, which exploit shelter effects or improve microclimatic and soil characteristics, and are also ‘ornamental’. The criteria for evaluating the characteristics of the site from the naturalistic and from the historical and landscaping points of view are explained. Also briefly. discussed, are congruity with the history and character of the site, overall compatibility with archaeological structures, usefulness for reconstructing specific environments, conservation Value for the site and aesthetic and economic criteria for the selection of species to introduce.     

Analytical methods for the conservation of the Buddhist temple II of Krasnaya Rechka,Kyrgyzstan

Abstract

The methods employed for selecting the repair material for the Buddhist temple II of Krasnaya Rechka, a site located in the upper Chuy Valley, Kyrgyzstan, are described in this article. The temple is built of mud brick and was excavated during several campaigns between 1938 and 1998 with no provision being made for conservation. The first emergency protective measures were initiated in 2003 during a UNESCO project that included other sites located in the Chuy valley. Most of the eroded walls of the temple were given a temporary shelter coat of mud bricks, a method that has proved effective. The main problem after proving the shelter coat was how to assess the repair material for future conservation work (it is planned to repeat the application of the shelter coat, but with materials with improved performance). Assessment was carried out after extensive laboratory analysis of both historic and repair materials, but also after test wall construction and monitoring. The methods explained here could be of use to conservators working in similar projects in the Middle East or Asia.     

Sheltering an archaeological structure in Petra A case-study of criteria,concepts, and implementation

Abstract

In 1993 an architectural competition for the construction of a shelter over a Byzantine church excavated in Petra between 1991 and 1992 was held by the American Center of Oriental Research in Amman, Jordan. While a prize was awarded, none of the concepts presented were translated into a construction project. A contract was instead awarded to architect Robert Shutler, who worked in close cooperation with Jordanian and international archaeologists and heritage managers, and a reversible space-frame shelter was built. This paper examines the issue of defining criteria for shelter construction, and stresses the need for cooperation among stakeholders and specialists as part of the conservation process from the decision to shelter to the implementation of the project.     

Middle Paleolithic Behavioral Organization: 1993 Excavation of Tor Faraj,Southern Jordan

Abstract

Excavation of a Levantine Mousterian rockshelter exposed two living floors in the upper part of a deposit more than 3.5 m thick. An intrasite study, focusing on the spatial patterns of data recovered from the two floors, complements an earlier intersite study of settlement and procurement patterns. The arrangement of hearths and the spatial distributions of artifacts and manuports indicate redundant behavioral organization for the two components. Moreover, the behavioral patterns reflected in site use by the occupants of the shelter some 70,000 years ago strongly resemble those recorded for modern foragers.     

Desiccated plant macrofossils from the medieval castle of Marmorera,Switzerland, with a note on the identification of leaves of Cyperaceae

Abstract

During restoration work at the medieval castle of Marmorera, Graubünden canton, Switzerland, numerous desiccated plant remains were found — in a rock crevice that was protected from precipitation by a massive rock shelter. The identification of the remains showed that the majority could not have grown at the castle, but must have been transported to the site. Many of the plants came from warmer climates and were imported from lower lying regions, indicating the position of the castle at an important transalpine route. Among the finds was a lump of grass-like leaves for which for a method of preparation and identification was developed. The leaves turned out to be of Carex species that grow in wet habitats which were probably used as litter or as bedding material.     

Interpreting the past: Presenting archaeological sites to the public

Abstract

A wide range of methodologies have been applied to promote the conservation of exposed and managed archaeological sites, including shelters. Commonly used as a protective measure in many areas of the world, shelters are not as common in the USA. In addition there have been few efforts to evaluate scientifically their use and efficacy. As a response to the recognized need to further scholarship and dialogue about shelters, a colloquium on the topic was held in Tumacacori, Arizona, in January 2001. The colloquium goals focused on research, exchange of information, the advancement of methodological approaches, incorporation of sheltering concepts into planning processes and identifying field needs. To achieve these aims, the following four themes were developed:

? deciding to shelter

? establishing conservation, design and construction criteria

? designing and constructing shelters

? evaluating shelter performance.

The colloquium followed a course of presentations, site visits and a final plenary session summing up the issues put forth. Participants represented a cross-section of disciplines and a range of international experiences.     

The Medieval Village at Garrow Tor,Bodmin Moor,Cornwall

SUMMARY

The site chosen for excavation in the medieval village at Garrow proved to be a platform-house, a variant of the long-house, a widespread form of peasant dwelling. Both types provided for the shelter of man and his beasts under one roof; in its early form, as here, it consisted of a living-room and byre separated by a passage connecting with an entrance in each long side. The platform-house was suited to meet the hard conditions of life in a hilly country of heavy rainfall. It was built on an oblong platform constructed with its long axis at right angles to the contours of the hillside. Thus the house gained considerable protection from wind and rain.

Two outstanding features were the hearth with fireback centrally placed on the floor in the upper room and the manger which was in situ in the byre. Near the house was a small barn. The two buildings stood in a small enclosure. Pottery found in the house and barn and in the fields connected with the settlement showed that there was occupation from the thirteenth to the fifteenth centuries. Inhabited farmhouses of this type can still be seen in Cornwall.¹     

SHEEPSHEAD COUNTRY: COASTAL WOODLAND SUBSISTENCE FROM THE PERSPECTIVE OF MACK BAYOU AND OTHER NORTHWEST FLORIDA SITES

Abstract

Zooarchaeological analysis of faunal remains from the Mack Bayou site produced new data related to coastal Woodland subsistence on the northern Gulf Coast of Florida. When the Mack Bayou data are compared with data from other Woodland sites on the northern Gulf Coast, a strong pattern of estuarine and shallow coastal waters utilization is evident, with notable but fairly minor site by site variation. It is also evident from these data that sheepshead (Archosargus probatocephalus) are a consistently important dietary component across the northern Gulf Coast, particularly on coastal sites in the Panhandle region of northwestern Florida.     

Conservation projects in Pergamon. Building Z and the shelter constructed above it

Abstract

The reconstruction and conservation of buildings in Pergamon has been an important aim of the excavations of the German Archaeological Institute Istanbul over the last twenty years. The paper discusses the structure known as Building Z situated about halfway up the slope to the acropolis of Pergamon on a rise between the terrace of the Sanctuary of Demeter and the precinct of the Temple of Hera. Although the southern fringes of this Hellenistic building were discovered in 1909, digging here was soon abandoned due to the very poor preservation of the walls. In 1990, a trench of the 'City Excavations' revealed the northern part of the building. The well-preserved Roman mosaic pavements and other remains found here — eventually exposing the best preserved examples of interior decoration yet discovered in the ancient city of Pergamon — prompted the construction of a shelter open to visitors. The construction of this shelter began in 1996 and was completed in 2004. The roofed area covers only the northern part of the former ancient building. The modern roof construction, on steel-trussed girders above the walls, has been deliberately designed as an independent unit.     

Foreign Jews in the western Alps (1938 – 43)

Abstract

This article examines the question of policy towards the Jews in the Italian occupied zone of southern France from 1940 to 1943. It develops the argument that in the World War II the Alps constituted a clearly demarcated geographical area that for Jewish refugees from all over Europe promised shelter and safety. A number of ‘exemplary cases’ (for example that of Angelo Donati) as well as an unpublished document relating to the case of ‘residence forcée’ in St Martin Vésubie, provided the opportunity for comparing different interpretations of Italian attitudes towards the Jews in those years.     

Excavation and Survey at Higher Woodhill Mill,Bury

Abstract

Recent landscaping and conservation works on the site of the long-demolished Higher Woodhill Mill provided an opportunity for limited excavation and recording work on this early water-powered cotton-spinning factory. Evidence suggested that a new large waterwheel and beam engine were installed as complementary features in the mid-nineteenth century, and the recent work concentrated upon the physical remains related to these features. Additionally, the historical development of the site appeared to reflect the progression of spinning technology through the water and throstle frames, and the self-acting mule.     

Afterword

ABSTRACT

In approaching history as a site of scholarly analysis and activist praxis, the papers in this volume open up new ways to think ethnographic and archival methods together. This afterword considers how these activist ethnographic representations work as part of the ethical and analytic commitments of contemporary anthropology more broadly. I ask what possibilities are opened when we as scholars think with other people’s struggles. Such dialogic encounter is a way in which activist anthropologies create possibilities for new imaginative frontiers and shared projects.
