The regional stream survey for east central Yukon (NTS 105N) was conducted during the summer of 1990.

This report presents analytical and statistical data for 37 elements in stream sediments from 783 sample sites, collected at an average density of one sample per 14.2 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.
