Surficial Geology Maps of Garner Creek and Matson Creek Areas, Yukon Territory

Late Tertiary and Quaternary geological data from the Lower Stewart River and adjacent Yukon River above Dawson. The dataset includes two 1:50,000-scale surficial geology maps and one 1:250,000-scale topographic map from the Government of Yukon, last updated in April 2026. Maps show field study sites, heavy mineral sample sites, and hardrock mineral occurrences.

Use Cases

• Identify potential placer gold deposit settings based on descriptions of multiple glaciations and proglacial outwash.
• Analyze sedimentology and stratigraphy of gravelly exposures for mining suitability.
• Map surficial geology and terrain features using the provided 1:50,000 and 1:250,000-scale maps.
• Assess physical characteristics of gravelly deposits for regulatory decisions on placer mining.

Strengths

• Includes two detailed 1:50,000-scale surficial geology maps.
• Includes one 1:250,000-scale topographic map with field study site locations.
• Focuses on a region with a documented history of placer gold discovery since 1884.
• Provides information on late Tertiary and Quaternary geology in a previously limited-study area.

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 map areas studied.
