Detailed surficial geology mapping from 2022 to 2024 for the area surrounding Haines Junction in southwestern Yukon. The map portrays properties of surface sediments and geomorphological processes, produced by the Government of Yukon. It is based on desktop interpretations of high-resolution lidar, air photo, and satellite imagery, supported by field investigations.
Use Cases
- Land use planning based on mapped surface sediment properties and geohazards.
- Archaeological investigations based on the surficial geology and history of Neoglacial Lake Alsek.
- Infrastructure risk assessment based on mapped geohazards such as landslides and permafrost thaw.
- Agricultural development planning based on soil texture and landform data.
- Permafrost monitoring and research based on mapped landforms like pingos and thermokarst ponds.
Strengths
- Mapping was conducted at a detailed 1:15 000 scale.
- Data collection spanned from 2022 to 2024, providing recent observations.
- Methodology integrated high-resolution lidar, air photos, satellite imagery, and field investigations.
- The map identifies specific permafrost landforms like pingos and thermokarst collapse ponds.
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 study area in southwestern Yukon.
