Yukon Surficial Geology Line Features at 1:250k Scale

A compilation of over 195 standardized surficial geology maps provides approximately 80% coverage of Yukon territory. The dataset includes line features such as geological contacts, glacial limits, and landforms like eskers and moraines. It was compiled by the Yukon Geological Survey from maps produced by various agencies.

Use Cases

• Map glacial limits and glacial landforms like eskers and moraines for paleo-environmental reconstruction.
• Analyze geological contacts and non-glacial landforms such as faults and landslides for geotechnical hazard assessment.
• Integrate line features depicting meltwater channels and cirques with polygon data for permafrost modeling.
• Use the standardized terrain classification for line features in land-use planning and granular resource assessments.

Strengths

• Compilation integrates over 195 individual maps into a standardized GIS format.
• Provides approximately 80% spatial coverage of the Yukon territory.
• Original feature descriptions are preserved alongside standardized Yukon terrain classification values.
• Includes a map index with publication details like author, title, and scale for each source map.

Limitations

• Spatial overlap exists between maps at different scales (1:250,000 to 1:10,000), which may complicate analysis.
• The dataset is a compilation from multiple original agencies, potentially introducing inconsistencies in original mapping methods.
