Cover Story: The Columbia Icefield in the Canadian Rockies serves is a major water source for the Columbia, Athabasca, North Saskatchewan, and Fraser River systems. The Columbia Icefield is one of the most visited tourist sites in North America. In this study, we measured the amount of retreat and change in areas of Columbia Icefield glaciers between 1985 and 2018. We used Landsat (TM 5 and OLI) satellite images. We concluded that all glaciers in the study region retreated and lost about 42 Km2 of its area. View this paper.
