Abstract
The South Nahanni River headwaters has the largest concentration of glaciers in the Northwest Territory. The majority of the glaciers 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 ecosystems 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 investigations in the glacier forelands, we provide a rudimentary description of the recent and past-century contraction of some notable glaciers in this region. We describe ongoing work that will lead to a better understanding of the variability of glacier cover, snowpack and related river flows in this region. This will provide a northward and eastward extension of perspectives on surface energy balance and hydrological inputs provided by several observing sites in the Rocky Mountains, Interior Ranges and Coast Mountains.
