Mapping Sxwóxwiymelh: A Pre-contact Settlement in the Upper Fraser Valley,Southwestern British Columbia

Abstract

Maps and mapping are fundamental to archaeology. Archaeologists sometimes fail to recognize that the maps we use and create are fraught, like material culture, with interpretive complexities. These complexities arise from the fact that maps are created with social meaning dependent on the context in which the map was created and used. Here, we relate our experience with maps and mapmaking at the pithouse settlement of Sxwóxwiymelh, in southwestern British Columbia. We review the mapping history of the site, highlighting the contexts in which the maps were constructed and how they influenced subsequent interpretations of the site. We describe our deconstruction of these earlier maps and how we combined them to create a more accurate and detailed map that presented a rendition of the site as it was prior to significant modern development. This process of map deconstruction and construction allowed us to see several previously unknown details about the ancient settlement (e.g., house form, relative house size, and feature spacing) of Sxwóxwiymelh. In general, this process provides conceptual and practical lessons for incorporating previously collected map data into archaeological research.     

Parameters in the use of pXRF for archaeological site prospection: a case study at the Reaume Fort Site,Central Minnesota

Field portable/hand-held x-ray fluorescence (pXRF) analyzers have been characterized as potentially useful for archaeological site prospection, but little has been published on the parameters of their use in this manner. The purpose of this study is to explore whether the variability of surface geochemistry as characterized with a pXRF analyzer corresponds with subsurface archaeological features at a site subsequently excavated, and what conditions influence the success of this endeavor, including feature depths, soil moisture, and sample processing. A 520 m² within-site area was systematically surveyed on a 2 m interval, within which several types of archaeological features were excavated (chimney bases, wall trenches, and a bonebed of faunal waste), taking readings in situ and collecting samples for ex situ testing (undried, dried but not powdered, and dried/powdered). The four different tests of each grid location, analyzed through univariate and multivariate tests, showed that the pXRF surface data does correspond with some types of subsurface features when those features are very shallow (within 5 cm of surface level) and are associated with clayey fills. Further, the data from the subsurface samples provides excellent distinction of feature fills from other sediments, regardless of sample preparation. In situ surface survey with pXRF analyzers may however be adequate for sites with a thorough baseline geochemical database.     

UNESCO World Heritage Site of Lenggong Valley,Malaysia: A Review of its Contemporary Heritage Management

This article reviews contemporary heritage management through a systematically coded content analysis at one of Malaysia’s UNESCO World Heritage Sites: the Archaeological Heritage of the Lenggong Valley (AHLV). It evaluates the competency of the preliminary Conservation Management Plan (CMP) of AHLV by looking at the accuracy of five distinctive dimensions of the CMP in conveying the information about the sites and management objectives: the legislation related to the heritage conservation and management; the action and implementation of the management strategies; the level of stakeholder’s participation; and, finally, how the CMP integrates local values and ideas into management planning. The results show that contemporary heritage management planning at Lenggong Valley tends to prioritize the conservation of the archaeological values of the sites over other values (i.e. social, historical, and aesthetic values), and that planning has largely been in the hands of governmental agencies with limited involvement from local communities in the decision-making process.     

Champaner‐Pavagadh Archaeological Park: A Design Approach

Champaner‐Pavagadh, like many other heritage sites in India, is both an historic and ethnographic landscape. It possesses a unique status as a medieval city—Champaner—frozen in time, more or less protected by its sudden abandonment 450 years ago. At the same time, it is a living sacred site—Pavagadh Hill—visited annually by millions, with a resident population. Efforts are underway to declare the hill and the remains of the medieval city at its foot an archaeological park, which will ensure protection and conservation of cultural and natural resources. The challenge in designing the site as an archaeological park lies in articulating the pastoral image conjured up by the term in a manner that does not belie complex issues of land ownership, varied use, and ecological integrity of the site. Working landscapes—farms, flower fields, orchards, and nurseries—can be employed as a landscape‐design typology to ensure sustainability and to preserve and frame sightlines to monuments. Garden archaeology is necessary to uncover the symbiotic relationship between buildings and gardens of medieval Champaner.     

The Challenges of Managing an Archaeological Heritage Site in a Declining Economy: The Case of Khami World Heritage Site in Zimbabwe

Abstract

This paper explores the case of the Khami archaeological site, whose degradation by the local communities in recent years was as a result of socio-economic problems caused by the collapse of the Zimbabwean economy combined with the inability of the Zimbabwean government to support the site. We argue that the negative attitude by the local communities towards the management of cultural heritage sites is embedded in the colonial history of the country, and has been driven by the socio-economic difficulties emanating from the collapse of the Zimbabwean economy in recent years. We begin by explaining the history of Khami, its architecture, and the local communities residing around it. We then show and assert that the subsequent degradation of Khami and the landscape around it by the local communities is linked to the socio-economic problems of the country and poverty, which emanated from the collapse of the Zimbabwean economy. In the end, we contend that the economic constraints are part of the reasons why the local communities have from time to time failed to respect the importance of protecting cultural heritage sites in the country.     

SHAKING TABLE DYNAMICS: RESULTS FROM A TEST-ANALYSIS COMPARISON STUDY

This paper presents the results of a comprehensive comparison study between the analytically predicted and experimentally identified dynamics of the shaking table system built recently in the Structural Engineering Laboratory at Rice University in Houston, Texas. The primary objectives of the research presented here are two-fold: (1) to shed light into the dynamic performance of asmall-tc-medium size, uni-axial, servo-hydraulic, displacement-controlled shaking table system, and (2) to validate a linearised dynamic model of the system (in the form of the total shaking table transfer function) developed earlier by the authors from basic principles. The analytical model incorporates the inherent dynamic characteristics of the various components of the shaking table system (i.e. controller, servovalve, actuator, test specimen, and reaction mass) and their dynamic interaction.

The test-analysis correlation study performed over a wide range of operating and payload conditions provides useful information on the sensitivity of the shaking table transfer function to control gain parameters and how it can be used to tune the shaking table controller for optimum performance under various payload conditions. The good test-analysis correlation results obtained validate the analytical shaking table model, show its robustness, and provide keen insight into the underlying coupled dynamics of a shaking table system. In order to achieve this good test-analysis correlation, it was crucial to include a time delay in the analytical model of the shaking table system (innovative feature of the model to account for the time lag in the response of the servovalve-actuator system). The expected significant dynamic interaction between payload and shaking table is also confirmed by this study.     

ON THE RESOLUTION OF H/V MEASUREMENTS TO DETERMINE SEDIMENT THICKNESS,A CASE STUDY ACROSS A NORMAL FAULT IN THE LOWER RHINE EMBAYMENT,GERMANY

In recent years, H/V measurements have been increasingly used to map the thickness of sediment fill in sedimentary basins in the context of seismic hazard assessment. This parameter is believed to be an important proxy for the site effects in sedimentary basins (e.g. in the Los Angeles basin). Here we present the results of a test using this approach across an active normal fault in a structurally well known situation. Measurements on a 50 km long profile with 1 km station spacing clearly show a change in the frequency of the fundamental peak of H/V ratios with increasing thickness of the sediment layer in the eastern part of the Lower Rhine Embayment. Subsequently, a section of 10 km length across the Erft-Sprung system, a normal fault with ca. 750 m vertical offset, was measured with a station distance of 100 m. Frequencies of the first and second peaks and the first trough in the H/V spectra are used in a simple resonance model to estimate depths of the bedrock. While the frequency of the first peak shows a large scatter for sediment depths larger than ca. 500 m, the frequency of the first trough follows the changing thickness of the sediments across the fault. The lateral resolution is in the range of the station distance of 100 m. A power law for the depth dependence of the S-wave velocity derived from down hole measurements in an earlier study [Budny, 1984] and power laws inverted from dispersion analysis of micro array measurements [Scherbaum et aL, 2002] agree with the results from the H/V ratios of this study.
