Abstract
Due to the increasing demand on water supplies, Alberta’s buried valleys have become important groundwater exploration targets. However, their location can be difficult to predict because they often have little surface expression, trend obliquely to slope, lack regional continuity, or are narrower than typical spacing of resource boreholes. Alberta Geological Survey has identified buried valleys at a range of scales, in a number of stratigraphic settings. These include regionally integrated preglacial valley systems, dendritic paleovalley networks and tunnel valleys related to meltwater drainage at the base of the Laurentide Ice Sheet. Sediment-fill sequences comprise 30 to 445 m thick deposits of fluvial sediment, stacked sequences of diamict, glaciofluvial sand and gravel and glaciolacustrine silt and clay, as well as postglacial sediments and displaced bedrock.
