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.

This report provides comprehensive documentation of landslide, permafrost subsidence and fluvial erosion-related geohazards for the Yukon portion of the Dempster Highway. It provides Yukon Department of Highways and Public Works – Transportation Engineering Branch a practical geohazard inventory that will help guide planning and mitigate future risk to the highway. It also becomes a valuable reference pertaining to slope stability, permafrost and fluvial processes in northern Yukon. Results from this study identified 54 mass movement geohazards and 102 meander-highway encroachment sites with the potential for future highway impact. Of particular significance, 75% of the mapped mass movement geohazards are influenced by permafrost or degrading permafrost, an important geological attribute considering future temperatures are expected to increase.
