Province / Territory: Yukon Territory
Funding Source: Federal and Territorial
Year of Collection: 1987
# Lake sites: 0
# Stream sites: 1266
Survey Area: 16608 km²
NTS Sheet(s): 105M (N 1/2), 115P
The regional stream survey for central Yukon (NTS 115P and the north half of 105M) was conducted during the summer of 1987.
This report presents analytical and statistical data for 20 elements in stream sediments from 1,266 sample sites, collected at an average density of one sample per 13.1 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.

Sediment samples from the north half of 105M were reanalyzed by INAA in 1988 and data released in Open File 1962 (with south half of 105M) in 1989. Subsequently, all sediment samples from 105M and 105N were reanalyzed for Bi and Se, and these data were released in 1998 as GSC OF 3685.
