Geology of southern Alberta and southwestern Saskatchewan

A unified hydrogeological conceptual model of the Milk River transboundary aquifer, traversing Alberta (Canada) and Montana (USA)

“…The study area is covered by glacial drift, except on the topographic highs (such as the Cypress Hills and the Sweet Grass Hills) and in the coulees (Williams and Dyer 1930;Colton et al 1961;Fullerton and Colton 1986;Robertson 1988). As the glacial drift consists mainly of lowpermeability till, the surficial deposits in the study area generally do not constitute productive aquifers (Borneuf 1976;Robertson 1988); however, the buried valleys can form very productive aquifers in southern Alberta (Farvolden et al 1963).…”
