Geologic Map Images of the Stillwater Complex at 1:12000 Scale

1974 scanned images provide raster versions of the five map sheets from the Geologic map of the Stillwater Complex, Montana by Page and Nokleberg. The collection includes four georeferenced MrSID files for the map sheets and one TIFF file for the explanation sheet. These images were created by scanning paper copies and georeferencing them to the Montana State Plane South coordinate system.

Use Cases

• Integrating raster map sheets (i797origs1.sid, i797origs2.sid, etc.) with vector data from the I-797 dataset for composite geological analysis.
• Using georeferenced MrSID images with .sdw and .aux files for precise spatial alignment in GIS software like ArcInfo.
• Analyzing the explanation sheet (i797origs5.tif) containing map symbols and unit descriptions to interpret features on the four main map sheets.

Strengths

• Five distinct map sheets provide coverage of the entire Stillwater Complex.
• Images are georeferenced to the Montana State Plane South coordinate system for spatial accuracy.

Limitations

• Data is from 1974 and may not reflect current geological knowledge or land features.
• The database is explicitly not meant for use at scales larger than 1:12000, limiting detailed analysis.
• Specific file sizes, resolution details, and scan quality metrics are not provided.
