Archaeomagnetic research in the Andean highlands
A Revision to the U.S. Southwest Archaeomagnetic Master Curve
Late Archaic Bison Hunters in Northern Colorado
Limited excavations at a Late Plains Archaic arroyo trap along the Cache la Poudre River near Windsor in northern Colorado have exposed the remains of an estimated 200 bison. The bonebed was uncovered during construction activities, which removed an estimated 4 m vf sediment from above tlie upper surface of the bone bed. Partial excavation of an 18.5 m2 cross-sectional portion of the arroyo has produced an assemblage of over 4000 bison bones. An …

Radiocarbon Dating Of Twenty-Seven Plains Complexes And Phases
Publication of large sets of radiocarbon dates, better radiocarbon calibrations, and the advent of high speed computers and software with which masses of data can be reanalyzed rapidly make it convenient and propitious to consider the absolute age of Plains phases. We find that a distribution of pooled radiocarbon probabilities reflects well the temporal information available for these phases and complexes, and that the distributions produce easi…

Archaeomagnetic Dating and the Bonito Phase Chronology
Archaeomagnetic Dating on the Great Plains
Archaeomagnetic dates are given for 41 samples from numerous archaeological sites on the Central, Southern, and High Plains. The archaeomagnetic samples are dated using the U.S. Southwest curve, because no curve exists for the Plains area. Both visual and statistical archaeomagnetic dates are provided, and “modified statistical dates” are derived to address current problems with the statistical dating method. Plains sample quality is discussed, a…
Archaeomagnetic Dating
Direct Dating of Prehistoric Canal Sediments Using Archaeomagnetism
The problems with dating prehistoric canals are renowned, due to the fact they seldom contain material appropriate for traditional dating methods. However, the application of archaeomagnetic techniques may offer a method of dating canals in those regions where master curves of polar wandering already exist. Detrital remanent magnetism in Hohokam canal sediments seems to produce accurate dates with ranges of ca. 200 years, twice the resolution of …
Dating the Hohokam Phase Sequence
In the past decade more than 700 archaeomagnetic samples have been collected from the Hohokam area of southern Arizona. Four hundred twenty of the dated archaeomagnetic samples could be assigned to specific phases and phase transitions and this large data set is useful in analyzing the absolute chronology of the Hohokam area. Mean dates and date ranges for each phase and transition provide the data for a new calibration of the Hohokam chronology …
Comparing Archaeomagnetic Pole Positions in Chronometric Analyses of Archaeological Components
Due to the large number of archaeomagnetic dates now available for the Hohokam region, archaeologists in the area have become increasingly interested in secondary analysis. Among the secondary analyses, comparison of archaeomagnetic samples or sets of samples in order to asses contemporaneity has been proposed as a particularly useful research approach. The three methods currently available to archaeologists are discussed and compared using data …
Contemporary archaeomagnetic results and the accuracy of archaeomagnetic dates
When multiple archaeomagnetic samples are collected from the same site or component, it is tempting to look for evidence of temporal differences between the collected features. This paper addresses the issue of the practical limits to confidently identifying temporal differences based on archaeomagnetic sample information. Three controlled data sets suggest that when the specimen polar projections of the samples compared have substantially overla…
A Reanalysis of First Reported Archaeomagnetic Dates from the Hohokam Area, Southern Arizona
Because of the inability to evaluate the primary data, archaeologists are questioning the accuracy of the first archaeomagnetic dates obtained from the Hohokam area in southern Arizona. Since many important dates have been disregarded in recent chronological reconstructions, an attempt is made in this article to reevaluate these first reported dates to ascertain whether or not significant information might still exist. A method of reanalysis is d…

A Mathematical Theory of Horse Adoption on The North American Plains
The horse complex and its subsequent influence on Plains culture is a major topic of Plains anthropology. Treatment of the topic has involved three trains of thoughts: 1) the process (form and rate) of horse adoption, 2) the spatial diffusion of the horse northward, and 3) the influence of the horse on Plains culture. This paper contributes to the study of the horse complex by focusing primarily on the adoption aspect of the problem and, secondar…
Archaeomagnetic Dating in the American Southwest
Although archaeomagnetic dating seems straightforward in principle, there are practical limitations which are not generally understood. Unlike rate-dependent processes such as isotopic dating, archaeomagnetic dating requires the construction of a master record of geomagnetic secular variation. Error is inherent in such a master curve due to statistical uncertainties regarding both the magnetic directions and ages of the samples used to create the…
Extension of niche theory in human ecology
Human ecologists have recently adopted a concept of niche as developed by Hutchinson (1957) that has become useful and operational in the study of human social behavior. This article extends this theory of niche by showing that the occupation of a human niche should theoretically grow in a logistic fashion, and that four empirical data sets conform to the expectation of logistic growth. Three patterns, all variants of a logistic curve, are recogn…
