Holocene stratigraphy and chronology of the Casper Dune Field, Casper, Wyoming, USA
Activation chronologies of dune fields within the North American Great Plains are significant sources of paleoclimate information. Although many regional chronologies exist, several dune fields have been understudied, including the Casper Dune Field of central Wyoming. This study investigated aeolian dune sediment and buried soils of the Casper Dune Field. Complex parabolic and hairpin parabolic dunes dominate the eastern dune field, while simple…
Late Quaternary sedimentology and geochronology of small playas on the Southern High Plains, Texas and New Mexico, U.S.A.
Playas are small, circular basins forming a ubiquitous component of the southern High Plains landscape. They are filled with carbonaceous mud deposited since the terminal Pleistocene. The stratigraphy and geochronology of 30 playas was investigated to better understand the paleoenvironmental record of basin filling. At the base of the fill in some playas is a well sorted eolian sand dated between ~ 13,000 and ~ 11,000 14 C yr BP. The beginning of…
Digital infra-red photography for recording painted rock art
Here is a new application of infra-red photography with a digital camera to record rock art. The need to make full and accurate records of the images, without touching (and thus degrading) the rock, requires a method of remote mapping. Trials with digital IR reported here are very promising and especially useful for painted rock art
Grass Phytolith Analysis
The vegetative history of eastern North Da kota is broadly known from pollen and multi-proxy investigations of lake basins from across the re gion (Clark et al. 2001; Dean and Schwalb 2000; Wright et al. 2004). These records suggest that parkland or savanna rapidly developed following glacial retreat and subsequent drainage of glacial Lake Agassiz to the south (10,800 to 9400 14C year B.P.) with true grasslands (or prairie) emerging by 9000 14C y…
Aeolian cliff-top deposits and buried soils in the White River Badlands, South Dakota, USA
Aeolian deposits in the North American Great Plains are important sources of Holocene palaeo environmental records. Although there are extensive studies on loess and dune records in the region, little is known about records in aeolian cliff-top deposits. These are common on table (mesa) edges in the White River Badlands. These sediments typically have loam and sandy-loam textures with dominantly very fine sand, 0.5–1% organic carbon and 0.5–5% Ca…
The Palaeoindian-Archaic transition in North America
The transition from Palaeoindian to Archaic societies in North America is often viewed as a linear progression over a brief but time-transgressive period. New evidence from the Wilson-Leonard site in Texas suggests social experimentation by Palaeoindians over a 2500-year period eventually resulted in Archaic societies. The process was neither short nor linear, and the evidence shows that different but contemporaneous lifeways existed in a variety…
Holocene environments of the central Great Plains
Wilson-Leonard An 11,000-year Archeological Record of Hunter-Gatherers in Central Texas Volume V
Study of the archeology of the Wilson-Leonard site has opened broad new vistas for the reexamination and improved interpretation of regional prehistory. Beyond that, it is of national importance in terms of both data and interpretation (for example, on the Paleoindian era) and the concepts used in its excavation and analysis. It is unique in other ways. In most cases, deep, stratified, multicomponent sites of this integrity are rarely excavated (…
The Holocene Phytolith Record from Morgan Playa in the Rolling Plains of Texas
Phytolith analyses of playa-fill sediments from Morgan Playa yield strong evidence for Holocene vegetation and climate change. Morgan Playa is located in the Rolling Plains of Garza County, north-central Texas. Backhoe excavation of the small (about 3.2 hectares) basin exposed 250 cm of Holocene age sediments. A strongly developed Early Holocene paleosol occurs at the base (205-250 cm) of the profile. Dark gray-brown, clayey playa sediments compo…
Phytolith and Carbon Isotope Evidence for Late Quaternary Vegetation and Climate Change in the Southern Black Hills, South Dakota
Analyses of phytoliths and carbon isotopes document change in late Quaternary grasslands in the Red Valley of the southern Black Hills. Late Pleistocene grassland composition was equivalent to the C 3 grass parklands of modern central Alberta. The rise of mixed grassland occurred rapidly between 11,000 and 9000 yr B.P. Early Holocene mixed grasslands included both short and tall C 4 grasses. A mid-Holocene erosional unconformity (ca. 8000 to 4500…
Crazy Mule’S Maps Of The Upper Missouri, 1877-1880
Two maps from the Joslyn Art Museum are identified as the work of John Crazy Mule, a northern Cheyenne scout who served at Fort Keogh, Montana Territory, from 1877 to about 1891. The maps were drawn in pencil and ink on ledger paper between 1877 and 1880. The first shows the Yellowstone and Milk drainages and is a record of Crazy Mule's accomplishments as a government scout. These include the Lame Deer fight and the capture of Chief Joseph's Nez …
Late Quaternary Pollen Record from Cheyenne Bottoms, Kansas
A sediment and pollen record from Cheyenne Bottoms, a large (166 km 2 ) enclosed basin in central Kansas, provides evidence for local and regional vegetation and climate change during the late Quaternary (ca. 30,000 yr.). Although radiocarbon dating of the carbonate-rich lacustrine sediments remains problematic, a basic chronological framework for the section is established. Two major litho- and biostratigraphic units, a Farmdalian zone (ca. 30,0…
Modern Phytolith Assemblages from the North American Great Plains
The analysis of fifty modem phytolith assemblages demonstrates the practicality of opal-phytolith analysis as a surrogate for pollen analysis in the North American Great Plains. The fifteen native grassland sites used in the study span both the east-west moisture and north-south temperature gradients of the central North American grasslands. Multiple soil samples analysed from each grassland site measure within-site variability and provide eviden…
Archaeological Investigations in the Clinton Lake Project Area, Northeastern Kansas, National Register Evaluation of 27 Prehistoric Sites
This report describes archaeological investigations at 27 prehistoric sites in the Clinton Lake Project Area, Douglas and Shawnee Counties, Kansas. The investigations were undertaken in order to determine the eligibility of the sites for the National Register of Historic Places. The results of the field and laboratory procedures have resulted in the following conclusions: The sites span at least the last 2000 to 3000 years of human history in the…
Palynological Evidence For a Late Prehistoric Vegetation Change In The Southern Black Hills From Cape's Cave (39FA205)
An interdisciplinary study of Cape's Cave (39FA205), a small rock shelter in the Southern Black Hills, South Dakota, revealed little evidence for human occupation of the site. Using current palynological laboratory techniques, significant fossil pollen assemblages were recovered from the cave sediment. Problems in interpreting pollen from archaeological contexts is briefly discussed, and the essential role of geomorphological and sedimentological…
