Paleodrainage Map of Beringia with 1 km Bathymetric Resolution

Government of Yukon provides a geospatial map reconstructing the paleodrainage and lake systems of Beringia, the land bridge between North America and Asia. The map is based on bathymetric data with a grid spacing of 1 km, and 100 m for Norton Sound. It was last updated on 2026-05-20.

Use Cases

• Modeling ancient human migration routes based on reconstructed land bridge geography.
• Analyzing paleoenvironmental conditions based on reconstructed lake and drainage systems.
• Studying the impact of glaciation on landscape evolution based on the bathymetric reconstruction.

Strengths

• Based on bathymetric data with a specified 1 km grid resolution.
• Includes higher 100 m resolution data for the Norton Sound area.
• Provides a reconstructed perspective on the environment of a significant paleogeographic feature.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
