The regional stream survey for southeastern Yukon (NTS 105G) was conducted during the summer of 1987.
This report presents analytical and statistical data for 20 elements in stream sediments from 913 sample sites, collected at an average density of one sample per 13 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.
