Abstract
The South Nahanni River headwaters contain the largest assemblage of glaciers in the Northwest Territory - glaciers that remain hereto unstudied. The majority of these are located in the Ragged Ranges of the Logan and Selwyn Mountains. River flow from these headwaters plays an important but yet to be comprehensively defined role in the functioning of eco-systems related to the South Nahanni River and its tributary, the Flat River. Using recent and historical remote sensing imagery, space-based geodesy and information from geobotanical assays conducted in the glacier foreland, we provide a rudimentary description of the recent and past-century contraction of some notable glaciers in this region. We describe ongoing work towards a better understand the variability of glacier cover, snowpack and related river flows for a region that serves as a northward and eastward extension of perspectives on surface energy balance and hydrological inputs provided by several observing sites in operation in the Rocky Mountains, Interior Ranges and Coast Mountains.
