S. E. Church, D.L. Fey, E. M. Brouwers, C. W. Holmes, Robert Blair
1999, Open-File Report 99-38
Determination of the pre-mining geochemical baseline in bed sediments and the paleoecology in a watershed impacted by historical mining activity is of utmost importance in establishing watershed restoration goals. We have approached this problem in the Animas River watershed using geomorphologic mapping methods to identify old pre-mining sediments. A systematic evaluation of possible sites...
Commemorative naming in the United States
Water Resources Division, U.S. Geological Survey
1999, Fact Sheet 158-99
Naming is a basic human tendency; it allows us to perceive the distinct identities of people and places and conveys those characteristics that make them unique. The name of a geographic feature can describe spectacular physical attributes (such as the Grand Canyon or Half Dome in Yosemite National Park), indicate...

Historical Mapping
Water Resources Division, U.S. Geological Survey
1999, Fact Sheet 154-99
Maps become out of date over time. Maps that are out of date, however, can be useful to historians, attorneys, environmentalists, genealogists, and others interested in researching the background of a particular area. Local historians can compare a series of maps of the same area compiled over a long period...

Stephen E. Cox, Sue C. Kahle
1999, Water-Resources Investigations Report 98-4195
Ground water is an important source of domestic, municipal, and irrigation water supply throughout the Fraser-Whatcom Lowland, particularly for the 225-square mile agricultural area surrounding the Whatcom County communities of Lynden, Everson, Nooksack, and Sumas and the British Columbia communities of Abbotsford and Aldergrove. Population growth and developing ground-water-quality problems...
The Virginia Beach shallow ground-water study
