- Silver City
town, seat (1874) of Grant county, southwestern New Mexico, U.S. It lies just east of the Continental Divide, at an altitude of 5,931 feet (1,808 metres) in the foothills of the Pinos Altos Range, on the edge of Gila National Forest (of which it is headquarters). It was established in 1870 as a Spanish settlement called San Vincente de la Ciénaga (Spanish: “St. Vincent of the Marsh”).Located in a mining area noted for silver, gold, copper, lead, and zinc, it was founded (1876) as Silver City and was a boomtown during the 1880s. The Santa Rita open-pit copper mine has been in operation since the early 1800s. The nearby ghost town of Tyrone has been revitalized as a copper-mining centre by the Phelps Dodge Corporation. Silver City serves an irrigated farm and ranch area, with some lumbering and tourism. It is the site of Western New Mexico University (1893). Fort Bayard State Hospital and Gila Cliff Dwellings National Monument are nearby. Inc. 1878. Pop. (1990) 10,683; (2000) 10,545.ghost town, Owyhee county, southwestern Idaho, U.S., 37 miles (60 km) southwest of Boise. Founded March 10, 1863, it quickly displaced Ruby City as the centre of the Owyhee mines and was county seat from 1866 to 1935. Rich silver lodes in the nearby War Eagle and Florida mountains were the subject of great excitement and bitter rivalry for control. A 500-pound (225-kg) silver crystal from the Poorman Mine won a gold medal at the Paris Exposition (1867). Silver City survived the collapse of the silver market that accompanied the failure of the Bank of California in 1875 because of its mines' advanced technology, extensive British investments, and improved railway transportation. Mining activity, however, gradually declined, leading to a complete loss of population. Silver City reached its peak population of some 2,500 about the turn of the 20th century, but it began a steady decline thereafter. In 1943 the U.S. post office was closed.
