Mass Movement Geohazards Inventory for Yukon's Dempster Highway

A geohazard inventory report documents landslide, permafrost subsidence, and fluvial erosion risks for the Yukon portion of the Dempster Highway. The study identified 54 mass movement geohazards and 102 meander-highway encroachment sites, with 75% of mass movements influenced by permafrost. It was published by the Government of Yukon and last updated in April 2026.

Use Cases

• Plan highway maintenance and risk mitigation based on mapped geohazard locations.
• Study permafrost degradation impacts on slope stability based on the reported 75% influence.
• Analyze fluvial erosion risk to infrastructure based on identified meander encroachment sites.
• Model future geohazard probability under climate warming scenarios based on permafrost-related attributes.

Strengths

• Quantifies 54 mass movement geohazards and 102 meander-highway encroachment sites.
• Reports a specific geological attribute: 75% of mapped mass movements are influenced by permafrost.
• Created for practical application by a government transportation engineering branch.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific highway corridor.
