Abstract: The Yukon Geological Survey (YGS), in collaboration with the Geological Survey of Canada (GSC), is preparing a geological highway map (1:2 000 000 scale) of the territory with a shaded relief base. Unlike a regular geological map whose legend shows rock formations in chronological order, this map emphasizes earth materials — nine rock types and six kinds of unconsolidated deposits — with less regard for their age. This map also shows major faults, hot springs, the location of other geological features of interest to the public, as well as primary and secondary road networks, communities and parks.
The geological highway map is accompanied by a series of illustrated time-slices of the tectonic evolution and glacial history of the territory. It is intended to be a territory-wide synthesis of Yukon’s geology — for residents as well as the rubber-tired tourist.
