Survey Description


During the summer of 1996, 229 lodgepole pine bark samples were collected in the Nechako project area, in the Nechako River region, central British Columbia.  Some samples were collected close to the location of till samples collected in a Quaternary survey, also part of the Nechako project.  Samples were obtained by scraping approximately 100 g of outer bark from around the circumference of mature trees.  The preferred sample interval was 2 km along roads, trails and tracks.  To minimize the effects of airborne contamination from roads, samples were collected at least 100 m into the forest.  Along less used trails, this distance was reduced to about 50 m.  The sampling grid is not even because of a lack of roads and trails in some areas.  The average sample coverage was approximately 1 site per 8 km2.  The data are published in Geological Survey of Canada Open File 3594 (a-d) and in GSC Open File 4356 as part of a geochemical compilation for the Nechako Project.
