The post-glacial paleoecology of the Morley Flats and Kananaskis Valley region, southwestern Alberta
Bibliography: p. 71-78 Quaternary paleoecological data is still relatively scarce for southwestern Alberta. Accordingly, the objective of this research is to provide information on the post-glacial paleoenvironmental history of the Morley Flats and Kananaskis Valley region of southwestern Alberta. I...

In pursuit of this goal, a radiometrically and tephrachronologically dated core from a small bog near the Yamnuska Centre on the Morley Flats and a radiometrically and tephrachronologically dated lacustrine sediment section from Wedge Lake in the Kananaskis Valley are examined in terms of several paleoecological parameters.
