| Abstract/Description or Keywords |
Subglacial land systems in and around Okanagan Valley are investigated in order to evaluate landscape development, subglacial hydrology and Cordilleran Ice Sheet dynamics along its southern margin. Over 600 m of Late Wisconsin-age sediments, consisting of a fining-up sequence of cobble gravel, sand and silt fill Okanagan Valley. Landform-substrate relationships, landform associations, and sedimentary sequences are incompatible with prevailing explanations of land system development centred mainly on deforming beds. They are best explained by meltwater erosion and deposition during ice sheet under-bursts. |
