Abstract
The term 'ice-free corridor' implies a single entity, fixed in time and space. Research in the 35 years since V. Prest published the first glacial retreat maps of North America demonstrate that while this 'entity' varies over time and space, it is still considered a singular phenomenon, rather than a complex palimpsest of geologic phenomena which themselves vary in time and space. This singular perception has provided a worthy target for those who would dismiss a land entry for the earliest Paleoindians into the lower-48 United States and has effectively shut off Paleoindian studies on the Canadian Northern Plains from anything but a sidelong glance. Retreat of both the Cordilleran ice masses and the Laurentide glacial advance produced a complex sequence of landscapes including large tracts of hummocky terrain, various glaciofluvial features, and glacial lake basins that may or may not have been habitable by people and animals. The rapidity with which Paleoindians occupied post-glacial Canada provides a distinct marker by which we can measure use of these landscapes. The Paleoindian occupation of post-glacial Canada also provides vital evidence regarding the peopling process, regardless of whether they traveled from the North or the South.
