Northern Dawson Range Surficial Geology, Soils, and Permafrost Mapping

Government of Yukon mapping characterizes the surficial geology, soils, and permafrost of the northern Dawson Range. The work was conducted to assist the mineral exploration industry, identifying widespread loess deposits and a mantle of weathered bedrock across the landscape. The dataset was last updated on 2026-04-17.

Use Cases

• Model landscape influences on soil geochemistry based on mapped surficial geology.
• Identify potential mineral exploration targets based on descriptions of weathered bedrock and loess deposits.
• Assess permafrost processes and their effects on surficial materials for regional development planning.

Strengths

• Mapping covers the entire landscape of the northern Dawson Range.
• Description includes specific findings on loess deposit thickness and location.
• Dataset is provided under the OGL-CA-2.0 open license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in HTML and PDF formats, which may require conversion for analysis.
