Yukon River Valley Ground Penetrating Radar Profiles, 270 km Survey

Ground penetrating radar profiles were collected along a 270 km stretch of the Yukon River valley between the White River confluence and Eagle, Alaska. The data, likely from the Government of Yukon, shows an average valley-fill gravel thickness of approximately 10 meters and suggests minimal recent vertical movement along the Tintina Fault. The dataset was last updated on 2026-04-17.

Use Cases

• Estimate valley-fill sediment thickness based on GPR profiles
• Assess bedrock depth and river scour depth equivalence
• Analyze tectonic stability by comparing fill depths across the Tintina Fault
• Model regional uplift rates using combined GPR and uplift history data

Strengths

• Survey covers a 270 km distance along the Yukon River
• Provides an average valley-fill gravel thickness of approximately 10 meters
• Includes observations across the Tintina Fault

Limitations

• Row count and column-level documentation are unknown
• Description metadata is limited; actual data quality requires manual inspection after download
• The profiles are described as preliminary
