The United States Geological Survey (USGS) was established by an act of Congress in 1879 to conduct scientific and systematic "classification of the public lands, and examination of the geological structure, mineral resources, and products of the national domain." Since that time the USGS has been collecting, analyzing, and publishing information about the countryÕs land, mineral, and water resources. [Description adapted from information supplied by the USGS.]
