Abstract
Some Pleistocene Lakes of Northern Alberta and Adjacent Areas
ABSTRACT
The extent of Pleistocene lakes in northern Alberta and adjacent areas is only partly shown on the 1958 Glacial Map of Canada. A large body of literature reporting on field work of the past 75 years describes the deposits of lakes that covered much of the basins of the Peace and Athabasca rivers. A striking example is Miette Lake, over 80 miles long, which lay across the continental divide in the headquarters of the Fraser and Athabasca rivers. Lakes of considerable size also existed in the western part of the basins of the North Saskatchewan and Churchill rivers, and in the Hay River basin. These basins were all complexly interconnected by spillways or accordant surfaces. Two large lakes (Peace and Tyrrell) covered more than 45 per cent of the northern half of Alberta's surface at various times.
