Recent field investigations have improved knowledge of Quaternary surficial geology, stratigraphy and glacial limits in southwest McQuesten map area (115P). The data likely contains information on pre-Reid glacial surfaces and evidence for large glacial lakes like 'glacial lake Coldspring' and 'glacial lake Rosebud'. It was published by the Government of Yukon and last updated on April 17, 2026.
Use Cases
- Mapping glacial limits based on field delineation at approximately 1000 m a.s.l.
- Analyzing stratigraphic exposures for evidence of large glacial lakes mentioned in the description.
- Supporting surficial geochemical exploration based on Quaternary geology applications.
- Correlating pre-Reid glacial surfaces with adjacent map sheets based on cited historical mapping.
Strengths
- Data is based on recent field investigations that improved geological knowledge.
- Includes specific elevation delineation for the pre-Reid glacial limit at approximately 1000 m.
- Correlates findings with historical mapping by Bostock (1964), Jackson (2005a,b), and Froese and Jackson (2005).
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 Yukon region.
