  • Approaches and challenges to the study of loess—Introduction to the LoessFest Special Issue

    Open AccessRandall J Schaetzl, E Arthur Bettis et al.ARTICLEQuaternary Research2018

    In September 2016, the annual meeting of the International Union for Quaternary Research’s Loess and Pedostratigraphy Focus Group, traditionally referred to as a LoessFest, met in Eau Claire, Wisconsin, USA. The 2016 LoessFest focused on “thin” loess deposits and loess transportation surfaces. This LoessFest included 75 registered participants from 10 countries. Almost half of the participants were from outside the United States, and 18 of the pa…

  • Origin of last-glacial loess in the western Yukon-Tanana Upland, central Alaska, USA

    Open AccessDaniel R Muhs, Jeffrey S Pigati et al.ARTICLEQuaternary Research2018

    Loess is widespread over Alaska, and its accumulation has traditionally been associated with glacial periods. Surprisingly, loess deposits securely dated to the last glacial period are rare in Alaska, and paleowind reconstructions for this time period are limited to inferences from dune orientations. We report a rare occurrence of loess deposits dating to the last glacial period, ~19 ka to ~12 ka, in the Yukon-Tanana Upland. Loess in this area is…

  • Chronology and provenance of last-glacial (peoria) loess in western iowa and paleoclimatic implications

    Open AccessDaniel R Muhs, E Arthur Bettis et al.ARTICLEQuaternary Research2013

    Geologic archives show that the Earth was dustier during the last glacial period. One model suggests that increased gustiness (stronger, more frequent winds) enhanced dustiness. We tested this at Loveland, Iowa, one of the thickest deposits of last-glacial-age (Peoria) loess in the world. Based on K/Rb and Ba/Rb, loess was derived not only from glaciogenic sources of the Missouri River, but also distal loess from non-glacial sources in Nebraska. …

  • Animals for food, animals for tools

    Clare Tolmie, James G Enloe et al.THESIS2013Referências: 76

    The adoption of bone tool technology in the Early Upper Palaeolithic of Europe by Neanderthals and anatomically modern humans has been the focus of considerable debate. In particular this debate has focused on the origins of the technology and the possible implications for the extinction of Neanderthals. This dissertation examines the context of element selection for use as raw material to produce bone tools, related to prey species in the Châtel…

  • A severe centennial-scale drought in midcontinental North America 4200 years ago and apparent global linkages

    Open AccessRobert K Booth, Stephen T Jackson et al.ARTICLEThe Holocene2005Citada por: 20Referências: 17

    We present evidence from a variety of physical and biological proxies for a severe drought that affected the mid-continent of North America between 4.1 and 4.3 ka. Rapid climate changes associated with the event had large and widespread ecological effects, including dune reactivation, forest fires and long-term changes in forest composition, highlighting a clear ecological vulnerability to similar future changes. Drought is also documented in the…

  • Unprecedented last-glacial mass accumulation rates determined by luminescence dating of loess from western Nebraska

    Open AccessHelen M Roberts, Daniel R Muhs et al.ARTICLEQuaternary Research2003

    A high-resolution chronology for Peoria (last glacial period) Loess from three sites in Nebraska, midcontinental North America, is determined by applying optically stimulated luminescence (OSL) dating to 35–50 μm quartz. At Bignell Hill, Nebraska, an OSL age of 25,000 yr near the contact of Peoria Loess with the underlying Gilman Canyon Formation shows that dust accumulation occurred early during the last glacial maximum (LGM), whereas at Devil’s…

  • Short contribution

    Open AccessRichard L Josephs, E Arthur BettisARTICLEGeoarchaeology2003Citada por: 2

    This note proposes a practical and economical alternative to using Kubiena boxes for the collection of undisturbed soil or sediment samples for micromorphological analysis. The authors promote the use of plastic electrical outlet boxes (gang boxes) that can be purchased at any hardware store for around 20 cents apiece. In addition to availability and low cost, plastic gang boxes are preferred by thin‐section laboratories over that of the aluminum…

  • Patterns in Holocene colluvium and alluvial fans across the prairie–forest transition in the midcontinent USA

    Open AccessE Arthur BettisARTICLEGeoarchaeology2003Citada por: 3Referências: 3

    The sediments composing alluvial fans and colluvial slopes harbor some of the most well‐preserved and continuous records of human habitation on the North American continent. Geoarchaeological investigations in the midcontinent of North America have revealed spatial and temporal patterns of sedimentation that control regional and local visibility, preservation, and distribution of archaeological deposits in colluvial slope and alluvial fan setting…

  • The effects of temporal and spatial patterns of Holocene erosion and alluviation on the archaeological record of the Central and Eastern Great Plains, U.S.A

    Open AccessE Arthur Bettis, Rolfe D MandelARTICLEGeoarchaeology2002

    Patterns of erosion and deposition act as a filter that strongly influences the disposition of the archaeological record of the Central and Eastern Plains of the North American Midcontinent. Detailed studies of alluvial valley stratigraphy in four drainage basins in the region reveal temporal and spatial patterns of fluvial system behavior that control the preservation and visibility of past human activity. These basins are located on a 600‐km‐lo…

  • Geochemical Variations in Peoria Loess of Western Iowa Indicate Paleowinds of Midcontinental North America during Last Glaciation

    Open AccessDaniel R Muhs, E Arthur BettisARTICLEQuaternary Research2000

    Peoria Loess deposited in western Iowa during the last glacial maximum (LGM) shows distinct geochemical and particle-size variations as a function of both depth and distance east of the Missouri River. Geochemical and particle-size data indicate that Peoria Loess in western Iowa probably had two sources: the Missouri River valley, and a source that lay to the west of the Missouri River. Both sources indicate that LGM paleowinds in western Iowa ha…

  • Late Quaternary Temporal and Event Classifications, Great Lakes Region, North America

    Open AccessW Hilton Johnson, Ardith K Hansel et al.ARTICLEQuaternary Research1997

    Several temporal and event classifications are used for the Quaternary glacial and interglacial record in the Great Lakes region of North America. Although based on contrasting principles, the classifications, as practiced, are similar to one another in most respects and they differ little from the classification proposed by Chamberlin a century ago. All are based on stratigraphic units having time-transgressive boundaries; thus the associated ti…

  • Impact of Euro-American settlement on a riparian landscape in northeast Iowa, midwestem USA

    Open AccessRichard G Baker, Donald P Schwert et al.ARTICLEThe Holocene1993Citada por: 2Referências: 3

    European settlement and attendant forest clearance and agricultural activities in northeastern Iowa caused changes in the landscape, vegetation, insect fauna and water quality unequalled in rate and magnitude since the melting of Wisconsinan glaciers. Historical documents show that the upper part of the Roberts Creek drainage basin was settled between AD 1840 and 1856, and the area was under intensive cultivation by 1880. Extensive soil erosion b…

  • Postglacial Response of a Stream in Central Iowa to Changes in Climate and Drainage Basin Factors

    Open AccessJulieann Van Nest, E Arthur BettisARTICLEQuaternary Research1990

    Postglacial geomorphic development of the Buchanan Drainage, a small tributary to the South Skunk River, is reconstructed by documenting relationships among four allostratigraphic units and 17 radiocarbon dates. Formation and headward expansion of the valley was both episodic and time-transgressive. Response to downstream conditions in the South Skunk River largely controlled the early formation of the basin. Downcutting through Pleistocene depos…

  • Early Holocene Pecan, Carya Illinoensis , in the Mississippi River Valley Near Muscatine, Iowa

    Open AccessE Arthur Bettis, Richard G Baker et al.ARTICLEQuaternary Research1990

    A fossil pecan, Carya illinoensis (Wang.) K. Koch, from floodplain sediments of the Mississippi River near Muscatine, Iowa, was accelerator-dated at 7280 ± 120 yr B.P. This discovery indicates that pecan was at or near its present northern limit by that time. Carya pollen profiles from the Mississippi River Trench indicate that hickory pollen percentages were much higher in the valley than at upland locations during the early Holocene. Pecan, the…
