Yukon Surficial Geology Line Features at 250k Scale

Yukon Geological Survey compiled over 195 surficial geology maps into a standardized GIS format, providing approximately 80% coverage of the territory. The compilation includes line features such as geological contacts, glacial limits, and landforms like eskers and moraines.

Use Cases

• Map glacial landforms like eskers and moraines for mineral and placer exploration targeting.
• Analyze line features including faults and landslides for geotechnical engineering and infrastructure planning.
• Model permafrost distribution using point features such as pingos and thermokarst depressions.
• Assess granular resources by analyzing polygon attributes like surficial material and texture.

Strengths

• Compilation integrates over 195 individual source maps from multiple agencies.
• Provides approximately 80% spatial coverage of the Yukon territory.
• Original feature descriptions are preserved and converted to a standardized terrain classification system.

Limitations

• Spatial overlap between maps of different scales (1:250,000 to 1:10,000) may create complexity for analysis.
• Dataset size and specific record counts are not provided in the input.
