The regional stream survey for central Yukon (NTS 105M) was conducted during the summers of 1987 and 1988. This report contains data previously released in Open File 1650 (published 1988), for the north half of NTS 105M surveyed in 1987.

This report presents analytical and statistical data for 20 elements in stream sediments from 861 sample sites, collected at an average density of one sample per 12.9 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.
