    Description:
      Abstract: This digital map database has been prepared by R.W. Tabor from the published Geologic map of the Chelan 30-Minute  Quadrangle, Washington.  Together with the accompanying text files as PDF, it provides information on the geologic structure and stratigraphy of the area covered.  The database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey.  The authors mapped most of the bedrock geology at 1:100,000 scale, but compiled Quaternary units at 1:24,000 scale.  The Quaternary contacts and structural data have been much simplified for the 1:100,000-scale map and database. The spatial resolution (scale) of the database is 1:100,000 or smaller.
    Purpose: This database depicts the distribution of geologic materials and structures at a regional (1:100,000) scale.  The report is intended to provide geologic information for the regional study of materials properties, earthquake shaking, landslide potential, mineral hazards, seismic velocity, and earthquake faults.  In addition, the report contains information and interpretations about the regional geologic history and framework.  However, the regional scale of this report does not provide sufficient detail for site development purposes.
     Supplemental_Information
DIGITAL COMPILATION- The United States Forest Service, Wenatchee Washington and/or their contractors scanned and vectorized the geologic map information from photographic reproduction of the printing negative, originally drafted from a stable ink-on-mylar author compilation at 1:100,000 scale. ARC/INFO vectorized coverage of the geology was later edited by R.W. Tabor to produce an coverage complete with faults etc.  R.W. Tabor hand-digitized structural and additional coverage data from scanned and georeferenced paper copy of the published map.
The digital compilation was done in versions 7.1.1 through 8.2 of ARC/INFO with version 3.0 of the menu interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991).  
BASE MAP-The geology of this dataset was mapped on dimensionally stable chronflex prints of the Chelan 1:100,000 scale topographic quadrangle.  Although no base map material is included in this dataset, a vectorized version of the base can be downloaded from http://edcftp.cr.usgs.gov/pub/data/DLG/100K/C/.   Registration of the DLG and some coverages in this dataset may not be a good as on the original published map due to instability of scanned paper copy. 
SPATIAL RESOLUTION- Uses of this digital geologic map should not violate the spatial resolution of the data.  Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data.  The fact that this database was edited for a scale of 1:100,000 means that higher resolution information is not present in the dataset.  Plotting at scales larger than 1:100,000 will not yield greater real detail, although it may reveal fine- scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.
