Yukon Surficial Geology Maps with 80% Territory Coverage

Yukon Geological Survey compiled over 195 surficial geology maps into standardized GIS datasets. The compilation provides approximately 80% coverage of Yukon territory, with map scales ranging from 1:250,000 to 1:10,000. Data includes polygon, line, and point features describing surficial material, texture, age, landforms, and permafrost features.

Use Cases

• Model permafrost distribution and thermokarst depression risk using point and polygon permafrost feature data.
• Assess granular resource potential by analyzing polygon attributes for surficial material and texture.
• Map glacial history and landform evolution using line features like eskers, moraines, and meltwater channels.
• Support geotechnical engineering and infrastructure planning with data on surface expression and landslide features.

Strengths

• Compilation of over 195 individual source maps into a standardized format.
• Approximately 80% spatial coverage of the Yukon territory.
• Includes polygon, line, and point features capturing diverse geological attributes.

Limitations

• Spatial overlap between maps of different scales (1:250,000 to 1:10,000) may create redundancy or require resolution decisions.
• Original maps produced by various agencies may introduce inconsistencies in original data collection methods.
