Four film positives of topography [which was prepared in 1943 andsubsequently used by Page and Nokleberg (1974) for a base map for thegeology of the Stillwater Complex, Montana] were scanned, and theresulting TIFF images were then geoferenced, rectified, and splicedtogether to create i797base.tif.
Geologic map datasets of the Custer and Gallatin National Forestsof South-central Montana, in ARC/INFO format: Absaroka-Beartooth study area
The digital ARC/INFO databases included in this directory provide a geologic map GIS database of the Absaroka-Beartooth study area (ABSA), a tract of approximately 1.4 million acres of National Forest land in southwestern Montana. The ABSA is adjacent to the northern part of Yellowstone National Park, and includes southeastern parts of Gallatin National Forest and western parts of the Custer National Forest. The geologic map was originally prepared to accompany a U.S. Geological Survey evaluation of the mineral resource potential within the ABSA. The results of this mineral resource assessment were published as U.S. Geological Survey Open-File Report 93-207 and the geologic map was plate 1 of this report. The enclosed...
This report provides a digital version of the Geologic map of theStillwater Complex, Montana originally published by N. Page andW. Nokleberg (1974). Paper copies of the four geologic mapsheets from the original report were scanned and initiallyattributed by Optronics Specialty Company (Northridge, CA) andremitted to the U.S. Geological Survey for further attributionand publication of the geospatial digital files. The resultingdigital geologic dataset can be queried in a geographicinformation system (GIS) in many ways to produce a variety ofgeological maps.
This collection of four georeferenced MrSID files and one TIFF fileprovides raster images of the five map sheets comprising the Geologicmap of the Stillwater Complex, Montana by Page and Nokleberg (1974).Paper copies of the four geologic map sheets and the explanation werescanned, and the geologic map sheets were georeferenced to the MontanaState Plane South coordinate system.
