Survey Description


In 1987, stream sediment follow-up surveys were carried out in Ragged Ranges and Nahanni Karst-Tlogotsho Plateau, the proposed expansion areas to Nahanni National Park Reserve as part of a resource assessment.  Based on the results from 1985 and 1986 surveys, anomalous streams were re-sampled.  In addition to this follow-up work, samples from previously untested, associated tributaries were taken at sites to fill in gaps where time had not permitted collection the previous summer.  A total of 84 samples were collected.  The data are published in Geological Survey of Canada Open File 1686.

Data from this survey are also included GSC Open File 5344, a resource assessment carried out in a larger area than was previously considered for expansion.

The geographic extent of the survey is defined by the following polygons:

  • Covers parts of NTS 105H (Frances Lake), 105I (Little Nahanni River), 95L (Glacier Lake) and 95E (Flat River), in the Ragged Ranges area of the Mackenzie Mountains, Northwest Territories.  It represents the western proposed extension area to Nahanni National Park Reserve.  It includes the park in its southeast corner.

  • Covers parts of NTS 95F (Virgina Falls), 95G (Sibbeston Lake), 95B (Fort Liard) and 95C (La Biche River), in the Nahanni Karst-Tlogotsho Plateau area, Northwest Territories.  It represents the eastern proposed extension area to Nahanni National Park Reserve.  The park runs east-west through the study area.
