The regional stream survey for north central Yukon (NTS 106E, 106L, 116H, 116I) was conducted during the summer of 1976.
This report presents analytical data for 12 elements in stream sediments, uranium, fluoride, and pH values in waters from these sites are included in this report. Samples were collected from 642 sites, at an average density of one sample per 11.6 km². For complete field observations refer to G.S.C. Paper 74 - 52.

Sediment samples were reanalyzed in 1995 by INAA for Au plus 25 additional elements. The reanalysis was carried out for the purposes of land use planning and results remained confidential until 2002, when the data were released by the Yukon Territorial Government.
