Commentary: Vernacular Regions of America

The practice of cross-timber log construction was one of the several culture traits the European immigrants brought to America beginning in the 17th century. Contrary to the opinions held by some observers, the tradition of log construction was introduced and implemented by the immigrants at different locations and different times. A familiarity with the evolution and characteristics of the European antecedents of log architecture is essential to the study of log construction in the United States. This study explores log architecture in a Finnish setting. Except for having contributed toward the development of the North European log construction technique before the migration to Finland, log architecture as practiced in Finland at the time of emigration to America, was more North European in character than “Finnish.” Moreover, folk traditions were in the process of change as they were subject to exposure to the invading industrial culture in the 19th century. The changes are manifest in log architecture as practiced at the time in Finland and on the cultural landscape the immigrants established in the United States.

Cabot Explorations in North America

Abstract

The map of Tenochtitlan published along with a Latin version of Hernán Cortés's letters (Nuremberg, 1524) was the first picture Europeans had of the Culhua‐Mexica city, the capital of the Aztec empire. The source of this woodcut map is unknown, and the author argues here that it was based on an indigenous map of the city. Once published in Europe, the city map and its companion map of the Gulf Coast, while certainly documentary, also assumed a symbolic function in supporting Cortés's (and thereby Spain's) just conquest of the Amerindian empire.     

The Hohokam of Southwest North America

The Hohokam reached an apex of sociopolitical development between the twelfth and fifteenth centuries in the Sonoran Desert of North America. Hallmarks of the Hohokam tradition included red-on-buff pottery, large-scale canal irrigation agriculture, and monumental buildings, including ball courts, platform mounds, towers, and Great Houses. The development and elaboration of Hohokam society from their ceramic-producing predecessors during more than two millennia (ca. 1000 B.C. to A.D. 1450, or later) is a remarkable example of an arid land adaptation in the New World. The enigmatic collapse of Hohokam society took place shortly before European colonialists entered the North American Southwest in the mid–sixteenth century. Various agents (e.g., floods, disease, warfare) of this event are poorly understood and require additional study. So, too, does the degree of historical continuity between contemporary indigenous peoples and precontact archaeological cultures (e.g., Hohokam) in what is now Arizona and northern Mexico.     

TWENTY DAYS OF Visit to North America

From February 5-25 this year, Chinese Tibetologists visited Canada, the United States andMexico. I was one of them.MEETING TIBETAN COMPATRIOTS IN CALGARYWe left Beijing for Calgary on the afternoon of February 5, but arrived in the Canadian city at noon of thesame day. We told ourselves we have flown from todayto yesterday.Soon after reaching our hotel, we were invited tomeet Tibetan compatriots. Some of them were thosewho left Tibet around 1959, and some others wereborn ab…

Explaining Shell-Tempered Pottery in Prehistoric Eastern North America

Explanations for the rise in frequency of shell-tempered pottery in the Eastern United States have vacillated between historical and functional accounts. Using evolutionary theory, the historical records of first appearance and diffusion are woven with physical properties of shell-tempered pottery that may have led to its selection. An appreciation of the scale at which change occurs and the units of analysis most appropriate for understanding that change is necessary for an explanation that can account for the widespread use of shell-tempering and the more-or-less coincident rise in its frequency. A hypothesis with empirical consequences is offered as a starting point for understanding this phenomenon.     

Thermal springs and heat flow in North America

Thermal springs are commonly thought to be an indicator of geothermal resource potential. However, there have been few analyses of the relationship between thermal springs and the underlying thermal regime. An examination of temperature and discharge rates for a large database of thermal springs in North America demonstrates that there is not a simple relationship between these measurements made at the surface and subsurface heat flow. Hydrogeological factors appear to exert strong controls on the temperature and discharge at these springs and should be carefully considered in geothermal resource assessments.     

Historical Archaeology and the Post-Columbian World of North America

Historical archaeology, with its interest in material culture and its use of the broader perspectives of anthropology and anthropological archaeology, has contributed to a distinctive understanding of the North American experience. Historical archaeologists have, to varying degrees, investigated the material traces of class, race, gender, and state formation. These studies provide an understanding of the origin of many of the social practices that undergird modern culture, a necessary, though neglected, case in a unified anthropological archaeology's goal of writing innovative world histories.     

Prehistoric demography of North America inferred from radiocarbon data

Large radiocarbon datasets are increasingly used as a paleodemographic proxy, although potential sources of bias in such records are poorly understood. In this paper, we use more than 25,000 radiocarbon dates extracted from the Canadian Archaeological Radiocarbon Database (CARD) to estimate long-term population trends in North America, while critically examining biases in such records. The frequency distribution of CARD dates shows a positive curvilinear pattern, such that older dates exist in lower numbers than more recent dates, which in part reflects the removal of cultural carbon from the archaeological record through processes such as erosion and dissolution. The average annual growth rate of radiocarbon dates in CARD was calculated and used to derive estimates of the population of North America from the Paleo-Indian to the Contact Periods. While taphonomic bias has likely affected the CARD data, other factors, such as the overrepresentation of Paleo-Indian and Archaic radiocarbon dates, may have offset any bias due to taphonomy. A quantitative reconstruction of Native American population shows that population increased rapidly around 2000 cal yr BP, reaching a maximum of 2,500,000 people by ～AD 1150. From this time until European contact, the population declined, possibly due to the effects of increased sedentism and population density.     

Prediction of High-Damping Seismic Demands in Eastern North America

This article investigates high-damping seismic demands and associated damping reduction factors in Eastern North America (ENA). A database of hybrid empirical records with moment magnitudes M ≥ 6.0 is first studied to evaluate 5%- to 30%-damped seismic demands. A new magnitude- and distance-based equation is proposed to predict ENA spectral displacements and then used to characterize their sensitivity to variations in period, magnitude, epicentral distance and site conditions. The proposed equation is also used to assess damping reduction factors in ENA. The results contribute to improved assessment of seismic demands in ENA while accounting for added-damping in structural seismic design.     

Multiple pathways to farming in precontact eastern North America

Hunter-gatherers in eastern North America utilized gourds at least 7000 years ago, operating at the early end of a sequence that ended with maize-based agriculture across most of the area. Various subregions differed from each other in timing and degree of participation in premaize crop production. A Midwestern record of native seed plant domestication preceding the adoption of maize is documented, and the significance of this phenomenon is now recognized. Recent archaeobotanical information highlights the amount of geographic variability, limiting the utility of earlier broad-scale interpretations. This paper includes a comparison of sequences in selected subregions: the Midwest/Midsouth, the Southeast, the Lower Mississippi Valley, the Trans-Mississippi South, and the Northeast.
