Geologic GIS Map of Saint Croix National Scenic Riverway, Wisconsin and Minnesota

A digital geologic-GIS dataset for the Saint Croix National Scenic Riverway, adapted from multiple Minnesota and Wisconsin Geological Survey source maps. The dataset is composed of GIS data layers and tables, available in formats including Esri file geodatabase, OGC geopackage, and KMZ/KML for Google Earth. It was last updated on March 13, 2026, and originates from the Department of the Interior.

Use Cases

• Conducting geologic resource evaluations based on the integrated geologic unit descriptions and GIS layers.
• Creating visualizations and analyses of bedrock depth and geologic features using the provided depth-to-bedrock and cross-section line data.
• Performing landscape and terrain modeling based on the geospatial layers representing geologic contacts and feature areas.
• Developing educational or interpretive materials for the national park using the user-friendly FAQ and ancillary map information documents.

Strengths

• Data is available in multiple GIS formats (Esri geodatabase, OGC geopackage, KMZ/KML) to support different software platforms.
• Includes comprehensive supporting documentation: a readme file, an ancillary map information PDF with unit descriptions, and a user-friendly FAQ metadata document.
• Integrates geologic mapping data from at least 11 different authoritative source maps produced by state geological surveys and the National Park Service.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The KMZ/KML format for Google Earth is limited in data layers presented and lacks access to ancillary table information.
• Row count and dataset size are unknown, which may limit suitability assessment for large-scale analysis.
