Cesium magnetometer surveys at a Pithouse Site near Silver City,New Mexico

The La Gila Encantada Site is located on an isolated ridge top north of Silver City, New Mexico in an area defined culturally as the Mimbres Mogollon region. The 180 m × 80 m (14400 m²) sized site was originally recorded as a dense scatter of ceramics, lithics, and ground stone along with a number of surface depressions that appear to represent pithouses. Cesium magnetometer surveys were conducted to identify hearths, pithouse boundaries, and activity areas outside of pithouses in support of archaeological investigations, and to test this instrument's ability to image these features. This paper presents a characterization of the magnetic signature of a pithouse as a magnetic high in the center caused by the central hearth, low magnetic variability along the floor of the house, and then increased magnetic variability at the pithouse boundary. This characterization was successfully confirmed for three pithouses using cesium magnetometery and archaeological excavation.     

Craft Production, Exchange, and Political Power in the Pre-Incaic Andes

This article explores the relationship between craft production, exchange, and power in the pre-Incaic Andes, with a focus on recent archaeological evidence from Chavín, Nasca, Tiwanaku, Wari, and Moche. I argue that craft production and exchange in concert with materialized ideologies played vital roles in the development of political power in the Andes. In later state societies, craft production, exchange, and materialization were critical in maintaining and legitimizing established political power.     

Protrusion, Bioturbation, and Settlement Detection during Surface Survey: The Lowland Maya Case

In upland settings in humid and semihumid temperate and tropical environments, bioturbation is a major factor in the burial of modest architectural remains, which are abundant components of the settlement systems of complex societies. Surface survey, favored by archaeologists of complex societies as a settlement detection method, seldom is appropriate for discovering architectural remains buried through bioturbation. Where the focus of analysis includes settlement represented by architectural remains, surface survey is appropriate only where all or a representative sample of all types of architectural remains are protrusive. Protrusion describes a relationship (affected by climate, environment, topography, and cultural variables) between the height of a ruined building and the depth of the biomantle, which is the zone of bioturbation. To enable archaeologists to assess the appropriateness of settlement detection procedures, including surface survey, I propose a scheme that classifies architectural remains in terms of their protrusion, building height, and visibility characteristics. The scheme can be employed to determine if and why architectural remains are protrusive in particular study areas. To demonstrate its analytical utility, I apply the scheme and the model of building burial through bioturbation that underlies it to the problem of Maya invisible settlement. I conclude that in the Maya lowlands of Mesoamerica, building remains buried through bioturbation are a more abundant settlement category than many archaeologists have supposed.     

The International Air Linkages of Australian Cities, 1985–1996

International air linkages are one of the important features differentiating the development of metropolitan areas, as the location of many activities now requires frequent and diverse international contacts. This paper explores the consequences of this for Australia by tracing the changes in international airline linkages over the past decade. In that time, the geography of the nation's air linkages have shifted in favour of the Asian nations to our north, reflecting the shifts in trade and immigration. Some cities have felt more of that change, with Cairns and Brisbane especially prominent due to their roles as gateways for the tourist industry. However, these shifts have yet to weaken the diversity of contacts in Melbourne and Sydney, indicating that the underlying geography of business still has a strong influence on the international contacts made from each city.     

The Effect of Federal Wilderness on County Growth in the Intermountain Western United States

A consistent theme in the debate over federally-owned wilderness areas in the intermountain western United States is that local economies may be adversely affected by such a designation. Yet empirical evidence of this negative effect is rarely offered. This paper finds, for a sample of 250 nonurban counties in the eight states of the intermountain west, no evidence that the existence of federal wilderness is directly or indirectly associated with either population-density or total-employment-density growth between 1980 and 1990. This empirical finding is based on a disequilibrium model of population and employment growth. Furthermore, much of the economic concern over wilderness designation centers on its perceived effect on resource-based industries. Yet, this study finds no empirical evidence that county-level resource-based employment is adversely affected by the existence of federal wilderness.     

A reconsideration of the West African macrolithic conundrum: new factory sites and an associated settlement in the Vallée du Serpent,Mali

Within West African prehistory, perhaps no period remains more mysterious than that between the Terminal Pleistocene and the mid-Holocene. This time period is shared by diverse macrolithic and microlithic industries. The macrolithic phenomenon has remained ill-defined, with most occurrences being generally lumped together as a single group, or attributed to earlier time periods. Recent archaeological investigations in the Vallée du Serpent and southern Gourma regions of Mali have revealed Holocene macrolithic assemblages quite different from the well-known bifacial traditions of Cap Manuel and Manianbougou, but not without parallels from elsewhere in the Sahel and Savanna. The most important of the Vallée du Serpent sites is that of Sirakoro-Ancien, where worked stone aggregations are associated with several rings of laterite cobbles believed to be the remnants of structures. Its lithic industry consists of massive flakes, perhaps removed directly from local outcrops, and smaller flakes from prepared cores as well as formal tools. Geomorphological and archaeological evidence suggests an age of the Vallée du Serpent sites somewhere between 9000 and 6000 bp. A new synthesis based upon sites investigated by the authors and the predominantly Francophone literature is presented in order to shed light upon this neglected portion of African prehistory.

Résumé Dans toute la préhistoire de l'Afrique occidentale, aucune période ne reste peut-être plus mystérieuse que celle située entre la fin du Pléistocène et le milieu de l'Holocène. Diverses industries macrolithiques et microlithiques se partagent cette période. Le phénomène macrolithique reste mal défini, la plupart des exemples en sont généralement rassemblés en un seul groupe, ou attribués à des périodes antérieures. Des recherches archéologiques effectuées dans les régions de la vallée du Serpent et du sud du Gourma au Mali ont révélé des collections macrolithiques de l'Holocène bien différentes des traditions bifaciales bien connues de Cap Manuel et Manianbougou, mais non sans parallèles ailleurs dans le Sahel et la Savanne. Le plus important des sites de la vallée du Serpent est celui de SirakoroAncien où des agrégats de pierres travaillées sont associés à plusieurs cercles de galets en latérite que l'on pense être des restes de structures. Cette industrie lithique consiste en éclats massifs, peut-être retirés directement de couches géologiques locales, et en éclats plus petits provenant de nucleus préparés ainsi que des outils. Des preuves géomorphologiques et archéologiques suggèrent que les sites de la vallée du Serpent ont entre 9000 et 6000 ans. Une nouvelle synthèse, fondée sur les sites étudiés par les auteurs et des documents principalement en français, est présentée afin d'éclairer cette partie négligée de la préhistoire africaine.
