AbstractThe physical properties of the surficial deposits of that part of the Kananaskis Lakes map area within Alberta, and physical processes that shape these deposits vary with the geological and geomorphologic setting in which they are found. Till and glaciolacustrine sediments in the Front Ranges have low plasticity indices due to their stony texture and large content of nonclay minerals in their clay size fractions. Many of the deposits in the Front Ranges are subject to rapid geomorphic processes of erosion and sedimentation, such as snow and rock avalanches, landslides, and debris flows. Tills of the Prairies and easternmost Foothills are Jess stony, are richer in clay, and have higher plasticity indices than those in the Front Ranges. Clay minerals in deposits of the Front Ranges are primarily illite, chlorite, and kaolinite; those in the easternmost Foothills and Prairies are interstratified montmorillonite and illite, chlorite, and kaolinite. Geomorphic processes acting upon deposits within this area are slow and noncatastrophic, except for flooding along streams. The Foothills belt proper is characterized by deposits and geomorphic processes intermediate and transitional between the Front Ranges and easternmost Foothills-Prairies. Surveys of existing foundation engineering data on surficial deposits are presented.
