Irwin, 1994). The map of selected post-Nevadan geologic features is in large part a compilation of the published work of many geologists (see Fig. 1--Index map showing sources of data). The principal focus of Map I-2148 concerned the assemblage of terranes that constitute the principal bedrock of the Klamath Mountains. The terranes of the Klamath Mountains variously consist of rocks that range from Cambrian to Late Jurassic and perhaps even earliest Cretaceous age. All of these terranes have been subjected to episodes of metamorphism, plutonism, and tectonism, including a major widespread tectonic event which occurred mainly in Jurassic time and which generally is referred to as the Nevadan orogeny. The geologic map database delineates map units that are identified by general age, lithology and clast size following the stratigraphic nomenclature of the U. S. Geological Survey. The scale of the source map limits the spatial resolution (scale) of the database to 1:500,000 or smaller. Purpose: To provide to the public a digital database of the Klamath mountain region.

Process_Step: Process_Description: The geologic map information was digitized from a stable original of the geologic map at 1:500,000 scale. The author manuscript (ink on a greenline) was scanned using a monochrome scanner with a resolution of 800 dots per inch. The scanned image was vectorized and transformed from scanner coordinates to projection coordinates with digitaltics placed by hand at latitude/longitude intersections. The scanned lines were edited interactively by hand using graphical user interface ALACARTE (Fitzgibbon, 1991, Fitzgibbon and Wentworth, 1991, Wentworth and Fitzgibbon, 1991). Scanning artifacts significant for display at a scale of 1:500,000 were corrected. The base map layer (kla-topo) was prepared by scanning a scale-stable clear film of a photo-mechanical of parts of the California and Oregon state topographic maps (scale = 1:750,000). The base map only contains the culture and drainage layers, contours are notincluded in this base layer. The clear film was scanned using a monochrome scanner with a resolution of 400 dots per inch. The raster scan was converted to a GRID in ARC/INFO. The GRID was then vectorized and reprojected into UTM Projection using the latitude/longitude intersections as reference points.
