These GIS files were used in the production of the Open-File Report OFSM 07-02.0: Surficial Geology of the Lopez 7.5-Minute Quadrangle, Sullivan and Wyoming Counties, Pennsylvania, located on the Pennsylvania Geological Survey web site at: http://www.dcnr.state.pa.us/topogeo/openfile/
The report was funded in part by the USGS National Cooperative Geologic Mapping Program.
Surficial Geologic mapping was done by Duane D. Braun of Bloomsburg University. Digital data production was done by Thomas G. Whitfield of the Pennsylvania Geological Survey.

Maps were prepared using ESRI software ArcInfo ArcMap 9.2. The base map Digital Raster Graphic (DRG) files of the 7.5-minute USGS quadrangle are not included with the shapefile and geodatabase data sets, but may be downloaded from PASDA in the form of uncropped DRGs, which contain full collar information, or cropped DRGs, which have the white collar digitally removed. Adjacent quadrangles as cropped DRGs may be displayed side by side, but they have a black artifact along the outside as a result of the clipping process. The artifact can be eliminated by turning off color #13. In addition, color #1 (white) and color #5 (forest green) can be made transparent to allow the data sets to show through.
Please note that the enclosed data and maps were created in ESRI ArcGIS 9.2. Although this data functioned properly on Pennsylvania Geological Survey equipment, it does not guarantee it will work on equipment outside the Bureau.
