This database of the Silt 7.5 minute quadrangle, originally released as U.S Geological Survey Open-File Report 94-696, has been updated to include a digitized database. The digitized version is also identifed as OFR 94-696. This geologic map was prepared as part of a study of digital methods and techniques as applied to complex geologic maps. The geologic map was scanned from the original greenline sheets used to prepare the published Open-File map of the Silt quadrangle (Shroba and others, 1994). Purpose: To provide to the public a digital geologic map of the Silt quadrangle, Garfield county, Colorado.

Process_Step: Process_Description: This geologic map was prepared as part of a study of digital methods and techniques as applied to complex geologic maps. The geologic map was scanned from the original greenline sheets used to prepare the published Open-File map of the Silt quadrangle (Shroba and others, 1994). Consequently, the digital version is at 1:24,000 scale using the Polyconic map projection parameters of the topographic base map. Stable base contact prints of the greenline sheets were scanned on an Ana Tech Eagle 408ET scanner to produce a .tif file. These files were then transferred to a Sun SPARCstation 20 computer where they were converted into ARC/INFO format. Each vector and polygon was given attributes derived from the original 1993 geologic map using ALACARTE (Wentworth and Fitzgibbon, 1991) software.
