Welcome to the Yukon Geological Survey's Integrated Data System (YGSIDS). We are in the process of merging all of our data into one system (see the current state of the conversion process). When this process is complete, the YGSIDS will include all of the Yukon Geological Survey's publicly accessible data.

Map Location


Mapping was carried out in the summer of 2018 by Rosie Cobbett and Halley Keevil for areas north of the Tintina fault; additional geological data provided by G. Jilson. Geology south of the Tintina fault is from YGS Open File 2002-9. Two areas north of the Tintina fault are extensively thermally and hydrothermally altered. The interpretation of fault traces through areas of poor rock exposure was guided by a Yukon wide geophysical survey of magnetic data.
