Survey Description


In the summer of 2005, truck and helicopter-supported stream sediment and water sampling was carried out at 49 sites on the Etsho Plateau, northeastern British Columbia.  In the summer of 2006, 80 stream sites were sampled in three east-west transects located between Fort St. John and Fort Nelson, northeastern British Columbia.

At each site a 125 ml water sample and approximately 2 kg of silt and clay were collected from the active part of the stream channel.  At 36 of the sites sampled in 2005 and 79 of those sampled in 2006, a coarse sediment sample weighing 10-15 kg after wet-sieving was also collected for additional geochemical and mineralogical analysis.

The data are published in Geological Survey of Canada Open File 6311. This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.

In the summer and fall of 2005, approximately 4 kg of till were collected at 140 sites in northeastern British Columbia.  Sample collection was carried out using trucks, all-terrain vehicles and a helicopter.  At 17 of these sites, bulk samples weighing approximately 25 kg were also collected for KIM analysis.  An additional 26 samples of primarily glaciofluvial sediment were also collected for KIM analysis.  A summary of the work can be found in BC Geological Fieldwork 2005 and 2006 (also includes selected data).

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

  • Covers parts of NTS 94I (Fontas River), N (Toad River), O (Maxhamish Lake) and P (Petitot River) in northeast British Columbia.  The Northern Alberta Uplands are located to the northeast and the Hyland Highland to the west.  Its centre is located approximately 50 km north of the community of Fort Nelson.

  • Covers part of NTS 94K (Tuchodi Lakes) in northeastern British Columbia.  It is located south of the Toad and Dunedin Rivers.  It encloses a single point.

  • Covers parts of NTS 94F (Ware), G (Trutch) and H (Beatton River) in northeastern British Columbia.  It is located south of the Muskwa Plateau.  Its centre is located approximately 140 km south of Fort Nelson.

  • Covers parts of NTS 94A (Charlie Lake), B (Halfway River) in northeastern British Columbia.  The town of Fort St. John is located within its boundary.
