Abstract
This update of the Yukon bedrock geology map builds upon the previous compilation by Gordey and Makepeace (1999, 2001). The dataset includes the bedrock geology, faults, and contacts; published by Yukon Geological Survey (January 2016). The new digital data is being released incrementally and will be updated regularly as new parts of the compilation are ready. Any errors noted by the user of this data should be reported promptly to the Yukon Geological Survey.

Yukon Bedrock Geology Map
This update of the Yukon bedrock geology map builds upon the previous compilation by Gordey and Makepeace (1999, 2001). It includes new, detailed bedrock geology maps and regional compilations that have been published by the Yukon Geological Survey and the Geological Survey of Canada, as well as some recent thesis works. A few of these maps were partially integrated into the digital dataset by Gordey and Makepeace (2003), but only as overlay to the 1999 compilation. A number of errors and omissions from the 1999 compilation of Gordey and Makepeace were also noted and corrected during compilation of this version of the map.
The Yukon bedrock geology GIS dataset is regularly updated and can be downloaded from the Yukon Geological Survey’s website: www.geology.gov.yk.ca. Users are advised to consult the website regularly to ensure they are working with the latest version of the geodatabase or shape files. This update of the GIS dataset includes an expanded attribute structure (compared to the 1999 dataset) that facilitates searching of the geodatabase.
This dataset requires the gscGeology font in order to properly label the bedrock polygons. This font file is packaged with the dataset when downloaded from geomaticsyukon.ca or geology.gov.yk.ca.
The Yukon Geological Survey aims to provide users with the best available geoscience data for Yukon. Any revisions or additional geological information known to the user would be welcomed by the Yukon Geological Survey.
