Stream sediment and water surveys were conducted in the Old Crow area of northwest Yukon during the summers of 2004 and 2005. These surveys were carried out under a Joint Research Agreement between the Yukon Government (Oil & Gas and Mineral Resources Division of the Department of Energy, Mines and Resources) and the Federal Government, acting through the Earth Science Sector's Metals in the Environment Program.
Analytical data accompany this document for 50 elements in stream sediments and 60 variables in waters from a total of 655 sites sampled in 2004 and 2005. National Geochemical Reconnaissance protocol was used for the collection, preparation and analysis of waters and silts.
