The Yukon Digital Bedrock Geology dataset was first released in 1999. It was rebuilt and expanded in 2016 and has since received regular updates. This paper summarizes the enhancements made to the bedrock geology dataset since 2016, the other ancillary geoscience datasets available, and the various ways to access and use the dataset.

These georeferenced pdf maps contain the most current bedrock geology information in Yukon. They are intended for use in software such as Avenza PDF Maps. The geological data used to create these maps can be downloaded at https://data.geology.gov.yk.ca/Compilation/3. These maps are subject to periodic updates. The Yukon Geological Survey welcomes any revisions or new geological information. Any questions or comments can be directed to geology@gov.yk.ca.

This update of the Yukon bedrock geology map builds upon the previous compilation by Gordey and Makepeace (1999, 2001). The data set includes the bedrock geology, faults and contacts, geochronology and map index; published by Yukon Geological Survey (January 2022). New digital data are 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.

Geological map (1:1,000,000 scale) of the Yukon Territory, including the following inset maps: terrane map; physiographic regions map; glacial limits map; aeromagnetic image map; and NTS index map.

Yukon Digital Geology presents a variety of geoscience data sets in digital format on the geology of Yukon. Included are syntheses of bedrock geology and glacial limits, compilations of geochronology, paleontology, mineral occurrences, oil and gas wells, and a compendium of aeromagnetic images. A subset of a public domain topographic data set (Digital Chart of the World, by ESRI, Inc.) is included for georeference purposes. For ease of use, data sets are divided geographically into 45 map tiles corresponding to the National Topographic System (NTS) 1:250,000 quadrangles. Data sets spanning the entire Yukon are also included. Each theme for all of the 45 map tiles is presented in two projections; an Albers Equal Area projection and UTM coordinate system. Vector data files are also presented in several different file formats (ArcInfo coverages; Interchange (*.e00), dBase (*.dbf), shapefiles (*.shp), and image data files are presented in band interleaved by line (*.bil), and tagged image file format (*.tif).

This is a re-release of data collected and published as the Yukon GEOPROCESS FILE between 1994-1996. The data set is a compilation of information and knowledge on geological processes and terrain hazards in the Yukon Territory. The original work was carried out in three phases from 1992 to 1995. Contractors performed the work under the supervision of the Environmental Geologist, Exploration and Geological Services Division, Yukon Region, Indian and Northern Affairs Canada. The following individuals and companies were involved in carrying out the project: Mougeot GeoAnalysis, Aurum Geological Consultants Inc., L. Walton and C. Hart.

The Yukon Geological Survey (YGS) has seen significant change over the last year, with eight new staff joining the team in 2024. This change has brought some new energy to the survey, enabling more visits to exploration projects and building the organization’s capacity to deliver geoscience. This report provides a snapshot of YGS’ staff and fiscal resources, and summarizes YGS’ 2024 activities and project highlights. Over the course of the year, YGS organized three workshops to assess current gaps in map coverage, seek input from clients about their needs, and consider how current trends such as interest in critical minerals and increasing frequency of landslides might influence YGS’ priorities in the future. Following each workshop, a list of project ideas for future work was compiled; these are summarized in this report. Gold prices in 2024 were high, averaging over C$3351 per ounce during the production season. This was a major driver for placer activity in the Yukon, which recorded the highest production on record since 1886. On a more somber note, the failure of the heap leach pad at Eagle Gold Mine in late June had a significantly negative impact on the First Nation of Na-Cho Nyäk Dun and the mineral industry in general. The medium to long-term effects of this incident on the environment and the mining sector are currently unclear.

Geographic Information Systems (GIS) spatial database of bedrock geology, surficial geology, mineral deposits, paleontology and geochronology for the Yukon Territory. It also contains a portfolio of georeferenced regional aeromagnetic images. All spatial database files are provided in two projections. The UTM coordinate system (disc 2) is commonly used at detailed scales. Albers equal area projection (disc 1) is provided to allow viewing or querying of larger areas that cross UTM zone boundaries. The datafiles are provided in various formats including an ARC/INFO coverage library, ARC/INFO interchange format (*.e00) and shapefile format (*.shp).
