A re-examination of the three most prominent Holocene tephra deposits in western Canada
Postglacial viability and colonization in North America’s ice-free corridor
During the Last Glacial Maximum, continental ice sheets isolated Beringia (northeast Siberia and northwest North America) from unglaciated North America. By around 15 to 14 thousand calibrated radiocarbon years before present (cal. kyr bp), glacial retreat opened an approximately 1,500-km-long corridor between the ice sheets. It remains unclear when plants and animals colonized this corridor and it became biologically viable for human migration. …
Evidence of cultural responses to the impact of the Mazama ash fall from deeply stratified archaeological sites in southern Alberta, Canada
Radiocarbon Dates of Late Quaternary Megafauna and Botanical Remains from Central Alberta, Canada
The chronologic record of late Quaternary biota from central Alberta has broad implications for understanding the archaeological, geological, paleontological, and paleoenvironmental record of western North America. Radiocarbon dates on remains of Pleistocene megafauna were previously used as proxies for the advance and retreat of ice sheets across Alberta (e.g. Young et al. 1994; Dyke 2005), and are important for understanding landscape changes t…
Late Pleistocene paleoecology of arctic ground squirrel ( Urocitellus parryii ) caches and nests from Interior Alaska's mammoth steppe ecosystem, USA
Botanical analyses of fossil and modern arctic ground squirrel ( Urocitellus parryii ) caches and nests have been used to reconstruct the past vegetation from some parts of Beringia, but such archives are understudied in Alaska. Five modern and four fossil samples from arctic ground squirrel caches and nests provide information on late Pleistocene vegetation in Eastern Beringia. Modern arctic ground squirrel caches from Alaska's arctic tundra wer…
Plant Macrofossils Associated with an Early Holocene Beaver Dam in Interior Alaska
Dynamic climate changes and expansion of new biomes characterize the late Pleistocene–early Holocene of eastern Beringia. Analysis of plant macrofossils from an early Holocene (ca. 9300 14C yrs BP) beaver dam in central Alaska provides insight into the local environment and vegetation. The plant macrofossil assemblage comprises remains of trees and shrubs, graminoids, and forbs, including Betula sp., Carex sp., Rubus sp., Eleocharis sp., Scirpus …
Legacy databases and GIS
Many institutions and agencies are currently faced with the issue of geographic information systems‐enabling legacy databases. The problems can be acute for data sets that have been compiled through many years, using different standards and levels of recording. To explore these issues further, we report on a data quality assessment undertaken in 2002 for a subset of the archaeological site database of the province of Alberta, Canada. Our work sho…
Macrofossil and pollen evidence for full-glacial steppe within an ecological mosaic along the Bluefish River, eastern Beringia
Radiocarbon Age Estimates from the SCAPE Project 2000–2005
This paper reports the results of 107 radiocarbon age estimates at and around the vicinity of four archaeological site localities in southwest Manitoba, central Saskatchewan, and southeast Alberta. Age estimates are reported from archaeological excavations, geomorphological and geoarchaeological investigations of the sites and relevant post-glacial landscape features, and from paleoenvironmental investigations. Pertinent laboratory and contextual…
Darkened Skies and Sparkling Grasses
Mazama ash has long served as an important chronostratigraphic marker for archaeologists working on the northwestern Plains. Despite its thickness and widespread distribution, few archaeologists have examined the potential impact of the ash fall on the plant, animal, and human communities of the area. To some extent, the failure to explore the consequences of this natural disaster reflects the paucity of historical documentation and the lack of c…
The Changing Ecophysical Landscape of Southern Alberta During the Late Pleistocene and Early Holocene
Competing models of Late Wisconsinan glacial advance, coalescence and retreat entail different opportunities for early human occupation of the developing ecophysicallandscape of interior western Canada. Of the current models, one postulates prolonged ice coalescence while the second suggests brief coalescence followed by a prolonged interval of deglaciation. Before we can model human occupation of the recently deglaciated landscape then, it is ne…
Recent Environmental Change in the Southwestern Canadian Plains
This paper examines 20th‐century environmental change in the subhumid southwestern Canadian Plains, specifically in relation to the dominant agricultural landscape and to the climate of the past millennium as reconstructed from proxy data. Anthropogenic landscape change in the last century has been dominated by the conversion of grasslands to ranchland and cropland. This has heightened landscape vulnerability to climatic fluctuations, especially …
Late quaternary landscape history and archaeology in the ‘Ice-Free Corridor’
Application of soil chemistry to interpret cultural events at the Calderwood Buffalo Jump (DkPj‐27), Southern Alberta, Canada
During excavation at Calderwood Buffalo Jump (DkPj‐27), southern Alberta, two profiles were sampled for soil chemical analysis. Transect samples were subjected to the phosphate ring test. The study objectives were to examine the effects of bison‐jump use on the soil profile, to investigate whether discrete jump‐use episodes could be identified within the soil profile, and to see if the ring test was useful in site delimitation. Comparative off‐si…
