Summary(Plain Language Summary, not published)
The Whitehorse Trough sedimentary basin of SW Yukon and NW British Columbia captured sediment, and then was shortened during and following accretion of the Intermontane terranes to the western margin of North America. We have used three low temperature thermochronometers to develop a temperature-time history for the sedimentary rocks in the basin, and then use that history to make a tectonic interpretation for the evolution of the basin.
