AbstractControversy over the age of the maximum known advances of continental and montane glaciers in southwestern Alberta rests largely on the paleoglaciology of the maximum montane piedmont glacier. Reconstruction of it, based upon features that mark the former glacier surface in the Foothills, indicate that the glacier had a maximum surface gradient of 0.4-0.6þ þ less than half the value assumed by previous workers. The continental ice sheet that was roughly coeval with the piedmont glacier and coalesced with it in the Foothills. Paleoglaciological evidence favours a Late Wisconsinan age for maximum extent of continental and montane ice.
