What does this data set describe?

Title:
Digital geological maps in the western Belt Basin, Kootenai, Bonner, Benewah and Shoshone counties, Idaho and Lincoln, Mineral, and Sanders counties, Montana
Abstract:
This metadata describes thirteen different geo-referenced tif images. Hand colored geological mapped data of the area in Sanders and Lincoln counties, Montana and Kootenai, Bonner, Benewah, and Shoshone counties, Idaho were converted to digital format (TIFF). These data were donated to US Geological Survey by the mineral industry. The area lies in the western part of the Belt Basin and contains metasedimentary rocks of Middle Proterozoic age. The area mainly contains rocks of the Prichard, Burke, Revett, St. Regis, Wallace, Empire and Spokane formations.
The source maps were scanned on an Ideal FSC 6010 36" width color pass through scanner at 200 ppi as 8 bit indexed color or in two instances at the 24 bit color level. Images were registered and rectified to provided neatline coverages in Universal Transverse Mercator zone 11 projection using ArcView Image Analysis Extension, version 1.1.
The source maps were non-published Asarco company maps representing different geographical areas. TIFF image names and their corresponding descriptions belonging to the Cabinet Mountains Reconnaissance program include: 
PL1R -Geologic map, Lincoln Co., MT,
PL2R - Geology and section location of southwestern Lincoln County,
PL3AR - plate 3a,
PL3BR - plate 3b -Geologic map Sanders Co., MT and Shoshone Co.,

  7. How does the data set describe geographic features?
    Entity_and_Attribute_Overview:
    Since each geologic map was digitized in its entirety, colors in the image generally represent geologic units, and other symbols appear as well. However the color should not be used uncritically, as it may vary across the defined unit as a result of the photographic imaging process.
    Entity_and_Attribute_Detail_Citation:
    Such details as are available will be found on the map images themselves, in the printed legends.
