Weighted mean age from glass-ITPFT age (119 spontaneous tracks) and glass DCFT (211 spontaneous tracks).The Thistle Creek section is about 100 km south of Dawson City, Yukon Territory, Canada, in the south Klondike goldfields. It consists of a 10 m thick organic-rich silt sequence over gravel on a terrace 25 m above Thistle Creek on the south side of the valley. Coordinates from Westgate and others (2009); datum not provided, assumed to be NAD83. Coordinates for this site in Preece and others (2011), Jensen and others (2011), and Reyes and others (2010) vary slightly.
