Preliminary integrated geologic map databases for the United States: Delaware, Maryland, New York, Pennsylvania, and Virginia
Connie L. Dicken, Suzanne W. Nicholson, John D. Horton, Scott A. Kinney, Gregory L. Gunther, Michael P. Foose, Julia A. L. Mueller
2005, Open-File Report 2005-1325
The growth in the use of Geographic Information Systems (GIS) has highlighted the need for regional and national digital geologic maps attributed with age and lithology information. Such maps can be conveniently used to generate derivative maps for purposes including mineral-resource assessment, metallogenic studies, tectonic studies, and environmental research....

Geologic map of the Great Smoky Mountains National Park region, Tennessee and North Carolina
Scott Southworth, Art Schultz, Danielle Denenny
2005, Open-File Report 2005-1225
The geology of the Great Smoky Mountain National Park (GSMNP) region of Tennessee and North Carolina was studied from 1993 to 2003 as part of a cooperative investigation with the National Park Service (NPS). This work has been compiled as a 1:100,000-scale map derived from mapping done at 1:24,000 and...
Preliminary integrated geologic map databases for the United States: Central states: Montana, Wyoming, Colorado, New Mexico, North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Texas, Iowa, Missouri, Arkansas, and Louisiana

Estimates of ground-water recharge based on streamflow-hydrograph methods: Pennsylvania
Dennis W. Risser, Randall W. Conger, James E. Ulrich, Michael P. Asmussen
2005, Open-File Report 2005-1333
This study, completed by the U.S. Geological Survey (USGS) in cooperation with the Pennsylvania Department of Conservation and Natural Resources, Bureau of Topographic and Geologic Survey (T&GS), provides estimates of ground-water recharge for watersheds throughout Pennsylvania computed by use of two automated streamflow-hydrograph-analysis methods--PART and RORA. The PART computer program...
The difference between the potentiometric surfaces of the Lower Patapsco Aquifer, September 1990 and September 2003 in Southern Maryland
Stephen E. Curtin, David C. Andreasen, Judith C. Wheeler
2005, Open-File Report 2005-1011
This report presents a map showing the change in the potentiometric surface of the Lower Patapsco aquifer in the Lower Patapsco Formation of Cretaceous age in Southern Maryland for September 1990 and September 2003. The map, based on water level measurements in 45 wells, shows that the change of the...
