Stillwater Complex Topographic Base Map from 1943

A 1:12000 scale topographic base map image of the Stillwater Complex in Montana. The image was created by scanning and geo-rectifying four film positives originally prepared in 1943 and later used by Page and Nokleberg (1974). It was archived by the organization CEOS_EXTRA.

Use Cases

• Use the geo-rectified TIFF image as a historical base layer for digitizing geological formations from the 1974 study.
• Analyze the 1943 topographic features for comparative studies with modern elevation data of the Stillwater Complex.
• Reference the 1:12000 scale map for field planning and spatial orientation in the specific Montana region.

Strengths

• Created from four scanned film positives that were geo-referenced and spliced together.
• Provides a specific, documented scale of 1:12000 for the base map.

Limitations

• The underlying topographic data is from 1943, making it temporally stale for modern analysis.
• The dataset is explicitly not meant for display or use at scales larger than 1:12000, limiting its resolution.
