Description
The glacial history and placer gold potential dataset from the Government of Yukon provides reconstructions and geomorphic mapping for the North McQuesten River, Dublin Gulch, and Keno Hill map areas. It details a succession of glaciations, including pre-Reid, Reid, and McConnell episodes, and analyzes placer potential based on geomorphology, glacial history, geochemistry, bedrock geology, and historic records. The dataset was last updated on April 17, 2026.
Use Cases
Mapping glacial limits and ice flow patterns based on geomorphic reconstructions.
Evaluating placer gold potential in drainages based on geomorphic evaluations and glacial history.
Analyzing the relationship between valley morphology and placer distribution based on glacial ice flow alignment.
Identifying prospective placer creeks based on integrated analysis of geochemistry, bedrock geology, and historic records.
Strengths
Analysis covers three distinct map areas (North McQuesten River, Dublin Gulch, Keno Hill).
Placer potential assessments integrate multiple data sources: geomorphic evaluations, glacial history, geochemistry, bedrock geology, and historic records.
Glacial history reconstruction identifies three main episodes: pre-Reid, Reid, and McConnell glaciations.
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 areas in the Yukon.
