Abstract
Landscape and vegetation have changed dramatically across the Canadian prairies, from the terminal late Pleistocene to the end of the middle Holocene. These transformations, in turn, are often assumed to have fundamentally impacted the ways in which Native Peoples have mapped on to these landscapes through time. In this study, a comparison of Folsom (11,000 – 10,000 BP) and McKean (4000 – 3000 BP) archaeological site distributions in the glacial Lake Hind basin of southwestern Manitoba illustrates the extent to which landscape evolution, environment, and settlement strategies are truly entangled. These site distributions are made meaningful in relation to lithostratigraphic and paleoecologic data obtained from a cutbank of the Souris River, in the Lauder Sandhills region of the Hind basin. Folsom incursions into the Hind basin correlate well with the period of gradual drainage of glacial Lake Hind, prior to ~ 10,400 BP. The regional clustering of McKean sites across the basin, furthermore, correlates with the initiation of extensive eolian landscape stability and the widespread development of a prairie wetland mosaic in this area. While both physical and biotic landscapes have changed dramatically through this period of time, however, both Folsom and McKean site distributions may reflect a highly similar land-use strategy.
