The Sister’s Hill Site: A Hell Gap Site In North-Central Wyoming

Abstract

The cultural horizon at the Sister’s Hill Site has produced typical Hell Gap points and a small group of associated artifacts. The radiocarbon date of 9650 ± 250 B. C. is in agreement with late Agate Basin or early post Agate Basin sites in the High Plains. On the basis of the current data, Hell Gap points appear to have developed from Agate Basin styles and seem to be developmental to Alberta, Scottsbluff and Eden types.     

Agate Basin Technology: An Insight

Abstract

An example of a serrate biface from the Agate Basin level of the Hell Gap site is examined from a technological and use-wear analytic perspective. Two possible explanations for marginal serration, to produce a “sawlike edge” or for platform isolation, are evaluated. Results of this evaluation suggest that platform isolation is a more plausible explanation in this case. This explanation may imply technological/cultural continuity between Folsom and Agate Basin biface manufacturing populations.     

The Sister’s Hill Site And Its Bearing On The Wyoming Postglacial Alluvial Chronology

Abstract

Alluvial sediments exposed at the Sister’s Hill Site near Buffalo, Johnson County, Wyoming shed new light on the stratigraphy of the Ucros s and Kaycee formations and reveal that another stratigraphic unit occurs between these formations in some places. At the Sister’s Hill Site, Hell Gap artifacts occur in the lower part of the new unit and in association with a Carbon-14 date of 9650 B. P.     

High Plains wheat mosaic virus: An enigmatic disease of wheat and corn causing the High Plains disease

Brief historyIn 1993, severe mosaic and necrosis symptoms were observed on corn (maize) and wheat from several Great Plains states of the USA. Based on the geographical location of infections, the disease was named High Plains disease and the causal agent was tentatively named High Plains virus. Subsequently, researchers renamed this virus as maize red stripe virus and wheat mosaic virus to represent the host and symptom phenotype of the virus. After sequencing the genome of the pathogen, the causal agent of High Plains disease was officially named as High Plains wheat mosaic virus. Hence, High Plains virus, maize red stripe virus, wheat mosaic virus, and High Plains wheat mosaic virus (HPWMoV) are synonyms for the causal agent of High Plains disease.TaxonomyHigh Plains wheat mosaic virus is one of the 21 definitive species in the genus Emaravirus in the family Fimoviridae.VirionThe genomic RNAs are encapsidated in thread‐like nucleocapsids in double‐membrane 80–200 nm spherical or ovoid virions.Genome characterizationThe HPWMoV genome consists of eight single‐stranded negative‐sense RNA segments encoding a single open reading frame (ORF) in each genomic RNA segment. RNA 1 is 6,981‐nucleotide (nt) long, coding for a 2,272 amino acid protein of RNA‐dependent RNA polymerase. RNA 2 is 2,211‐nt long and codes for a 667 amino acid glycoprotein precursor. RNA 3 has two variants of 1,439‐ and 1,441‐nt length that code for 286 and 289 amino acid nucleocapsid proteins, respectively. RNA 4 is 1,682‐nt long, coding for a 364 amino acid protein. RNA 5 and RNA 6 are 1,715‐ and 1,752‐nt long, respectively, and code for 478 and 492 amino acid proteins, respectively. RNA 7 and RNA 8 are 1,434‐ and 1,339‐nt long, code for 305 and 176 amino acid proteins, respectively.Biological propertiesHPWMoV can infect wheat, corn (maize), barley, rye brome, oat, rye, green foxtail, yellow foxtail, and foxtail barley. HPWMoV is transmitted by the wheat curl mite and through corn seed.Disease managementGenetic resistance against HPWMoV in wheat is not available, but most commercial corn hybrids are resistant while sweet corn varieties remain susceptible. Even though corn hybrids are resistant to virus, it still serves as a green bridge host that enables mites to carry the virus from corn to new crop wheat in the autumn. The main management strategy for High Plains disease in wheat relies on the management of green bridge hosts. Cultural practices such as avoiding early planting can be used to avoid mite buildup and virus infections.     

Craniometric Relationships of Plains Populations: Historical and Evolutionary Implications

Abstract

Large skeletal samples from cemeteries in the Northern Plains near Mobridge, South Dakota have made possible the accurate determination of craniometric relationships between populations ancestoral to the historic Arikara. There is considerable change throughout the approximately 200 years represented, due primarily to gene flow from adjacent Siouan speaking groups. Arikara crania from the Northern Plains are seen to be morphologically similar to earlier crania further south, in particular St. Helena materials in northeastern Nebraska. This offers Support for the archaeological hypothesis that Coalescent Tradition cultures grew out of the Central Plains Tradition. Early crania from the Northern Plains are markedly different from those in the Central Plains and more similar to historic Mandan. The craniometric evidence argues for biological continuity rather than replacement in the Plains area.     

T-W-DIamond,a Stone Ring Site in Northern Colorado

Abstract

The T-W-Diamond Site, 4LR200, is a large teepee ring village on the? edge of the High Plains in northern Colorado. Seventeen out of the 47 remaining stone ring areas were excavated or tested by the Colorado State University Archae-ological Field School in 1971. Artifacts, fire hearths and midden materials were scarce but indicated the domestic nature of the structures. Stone and ceramic artifacts indicate cultural affiliations with the Late Prehistoric period as reported at Birdshead Cave, and the Piney Creek sites in Wyoming; and at the Agate Bluff Rock Shelters, and the Dipper Gap site in northern Colorado. Carbon-14 dates of A. D. 1020±230 years and A.D. 1170±220 years support the time of the occupation. A third date of A.D. 400±340 seems improbably early. It is hypothesized that the village was occupied seasonally for a short time by a small group of people, perhaps of Shoshonean affiliation, exploiting a mixedbase subsistence economy.     

Was There a Northwestern Plains Sub-Culture? An Ethnographical Appraisal*

Abstract

On the basis of an examination of economy, political organization, intertribal warfare, religious life, and other factors, there is no justification for regarding the Northwestern Plains as a distinct division of the Plains Indian Culture Area.     

A Reexamination of Roper’S Trend-Surface Analysis of Central Plains Radiocarbon Dates

Abstract

A reexamination of Roper’s (1976) trend-surface analysis of Central Plains radiocarbon dates indicates that 1) a nonlinear trend in the data was not recognized, and 2) the dates of the trend-surface contours given in her map of the Central Plains are in error. A revised trend-surface model is presented which better describes the site data and more closely agrees with the Central Plains cultural sequence.     

Introduction

Abstract

In the space of 20 years the Plains region has progressed from one of the least known to one of the better known regions as far as skeletal studies are concerned. This paper reviews the development of skeletal biology and the accumulation of the large, well documented samples. It provides up-to-date bibliographic citations of the recent literature relating to the United States Plains, including M.A. theses and Ph.D. dissertations which deal with or utilize Plains skeletal material.     

The Great Bend Aspect: A Multivariate Investigation Of Its Origins And Southern Plains Relationships

Abstract

The origins of the Great Bend aspect as well as its relations with a series of southern Plains sites are analyzed using ceramic attributes and multivariate statistics. Although the data is inadequate in certain areas the results suggest that in-situ development from earlier cultural groups is a more likely explanation than is a migration of peoples from the southern Plains.     

The Plains Agon - A Gross Typology

Abstract

In the prevailing view of Plains experts the classic post-horse, post-gun agon (the total physical and psychological military complex) consisted of either two or three different types of military event, generally divided into “scalp raids” and “horse raids.” The literature on Plains agonistics indicates, however, that the Equestrian pattern of intergroup hostilities consisted of at least seven disti net types of military operations.     

Recent Gully Formation In Prairie Areas Of The Northern. Great Plains*

Abstract

Modern gully formation in the Great Plains and Southwestern United States has been attributed variously to overgrazing, farming, and climatic change. Pre-settlement prairie fires in the Northern Great Plains burned the protective vegetation so that gradients of drainageways were adjusted to more sediment than they receive today when wild fires are uncommon. Gully cutting may be an adjustment of the gradient to new conditions. Erosion caused by overgrazing today may not be different from that caused by wild grazing animals in the pre-settlement period.     

Avonlea Point Occurrence in Northern Montana and Canada

Abstract

This report is a follow up of the 1961 Kehoe-McCorquodale presentation in the Plains Anthrdpqlogist of the Avonlea point as a horizon marker for the Late Prehistoric Periood in the Northwestern Plains, Montana Avonlea data are discussed, compared and combined with Canadian data to develop an expanded picture of regional Avonlea “culture”. A critique of the kehoe-McCorquodale generalizations reinforces essential hypothesis and further clarifies Avonlea spatial and temporal parameters.     

The AvonLea Point

Abstract

The authors define a readily distinguished type of small, triangular, side-rotched projectile point previously assigned to the Late Prehistoric Period of the northwestern Plains but which was thought too generalized to be used in studies of cultural and ethnic affiliation.

Type sites are described, geographical distributions made, and factors considered which may have influenced the development of this point type in southwestern Saskatchewan.

It is concluded that the Avonlea point is sufficiently unique and temporally delimited to serve as a useful marker for the early Late Prehistoric Period in the northwestern Plains.     

The Red River Valley In The Prehistory Of The Northern Plains

Abstract

Archaeological reconnaissance in the valley of the Red River of the North indicates a heavy utilization of this area by Late Woodland peoples, especially manufacturers of Sandy Lake pottery. Artifact style, raw materials procurement, and the general pattern of northern Plains trade suggest the Red River area was integrated into a larger reticulum joining the northern Midwest woodlands with the northern Plains. Referring to this region as a “periphery” is acceptable only in a geographic sense, not a cultural-historical sense.     

A Shoshonean Origin for the Plains Shield Bearing Warrior Motif

Abstract

The shield bearing warrior is a distinctive motif characteristic of the rock art of the Northwestern Plains. It also occurs commonly in the eastern Great Basin as an element of Fremont rock art. Detailed similarities between Plains and Great Basin shield figures suggest cultural relationships between the two areas. This has led some authors to propose that the motif originated in the Northwestern Plains and diffused to the Great Basin. Others argue that the motif spread from the Great Basin to the Plains. Relative dates recently obtained for shield figures at Northwestern Plains sites support the latter hypothesis. A Shoshonean origin for the Northwestern Plains shield figures is suggested by the dates, and the coincidence between the distribution of the motif, the distribution of diagnostic Shoshonean artifacts. and the ethnohistorically known range of the Plains Shoshone. It is suggested that the Shoshone borrowed the motif from the Fremont Culture during a period of interaction between the two groups.

The shield bearing warrior, a distinctive motif that depicts a pedestrian warrior whose body is represented by a large circular shield (Fig. 1), is frequently encountered in the rock art of the western United States. It is especially common at sites on the Northwestern Plains and in the eastern Great Basin (Fig. 2).     

Some Wooden Scraper Handles From the Great Plains and The Southwest

Abstract

Adze-shaped scraper handles of antler are well known from the Plains area. Tools of the same pattern, of wood, are less well known and are virtually unmentioned in the literature and the tool in both antler and wood is unmentioned from the Pueblo area. Data on size and distribution of a large group of these objects in wood, from both the Plains and the Pueblo area are presented here, with some discussion of their possible origin.
