Abstract | The Kananaskis Research Forest-Marmot Creek Basin lies along the Kananaskis River within the front ranges of the Rocky Mountains, some fifty miles west of Calgary. The mapped area covers 54 square
miles. Four major glacier s are recorded, each smaller than the previous one. The first three advanced down Kananaskis Valley to join glaciers in Bow Valley, north of t h e area, but the fourth apparently terminated in the region of Barrier Lake,
short of the Bow Valley. The first covered all but the highest points in the area but, as all the glaciers left very little drift in upland districts, bedrock is exposed over three-auarters of the area. Frostproduced rubble covers much of the
unglaciated area. The bulk of the surficial deposits are found in the valleys. They consist of: glacial deposits of outwash and valley fill; glacial and postglacial deposits laid down in streams and lakes during retreat of the last glacier. Generally
while Bow Valley ice blocked t h e north end of Kananaskis Valley; and postglacial stream, fan and mass wasting deposits. Ground moraine, fan deposits, and post glacial alluvium form most of the surficial cover, but outwash and lake sediment
predominate in certain parts of the Research Forest. The four glaciers probably span all Wisconsin, and perhaps some pre-Wis consin, time. It is suggested that t h e last reached its maximum between 12, OOO and 10, OOO years ago, and that it
corresponds to the Canmore advance in Bow Valley. |
