  This digital database was compiled in ArcGIS version 10 
  personal geodatabase format and consists of geologic map 
  feature classes for each of the two printed map sheets 
  (Sheet 1 and Sheet 2) from the Geologic Map of Newberry 
  Volcano, Deschutes, Klamath, and Lake Counties, Oregon; 
  U.S. Geological Survey Miscellaneous Investigations Series 
  Map I-2455.  ArcGIS-compatible GIS software is, therefore, 
  required to use the files of this database.  The 
  geodatabase is stored in a single zipped folder (6.58 MB in 
  size) in this release for ease of transfer.  The scale of 
  the source mapping limits the spatial resolution of the 
  database to 1:62,500 scale or less detailed for Sheet 1 and 
  1:24,000 scale or less detailed for Sheet 2.
