Seagull Creek Surficial Geology Map at 1:50,000 Scale

The Seagull Creek map area covers the upper two-thirds of the Seagull Creek drainage basin in Yukon, Canada. It includes summits up to 2162 m elevation, a 30 km valley, and ubiquitous evidence of glaciation such as arêtes, cirques, rock glaciers, and tarn lakes. The dataset is provided by the Government of Yukon and was last updated in April 2026.

Use Cases

• Mapping glacial landforms based on descriptions of arêtes, horns, and cirques.
• Analyzing terrain stability based on mentions of over-steepened valley sides susceptible to mass movements.
• Studying hydrological systems based on the described drainage area, valley, and tarn lakes.
• Assessing elevation and topography based on the specified summit heights and valley floor elevations.

Strengths

• Map is produced at a detailed 1:50,000 scale.
• Description provides specific elevation data (1372 m valley floor, 2162 m summits) and geographic extent (30 km valley).
• Focuses on a landscape with ubiquitous evidence of glaciation, offering a concentrated 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 format is HTML/PDF, which may require conversion for quantitative analysis.
