city, Shoshone county, northern Idaho, U.S. It is situated in the Coeur d'Alene mining district of the Bitterroot Range. Established as a prospecting camp in 1893 and originally called Milo, it was renamed (1894) to honour Noah S. Kellogg, discoverer of the Bunker Hill Mine. The community developed as a mining and smelting centre for lead, zinc, and silver. Bunker Hill (combined with the Sullivan) is one of the world's largest lead mines. The Sunshine Mine, a few miles east of Kellogg, is one of the largest single-lode producers of silver in the United States; in 1972 it was the scene of a disastrous fire that killed 91 miners. A downturn in the world metals-production market led to severe layoffs in the 1980s, and production was limited thereafter. The mining activities in the region also made it “one of the largest and most complex abandoned hazardous waste sites” in the United States; cleanup was in progress at the turn of the 21st century. Nearby Silver Mountain is a popular skiing area that features the world's longest single-stage gondola. The Cataldo Old Mission of the Sacred Heart (1848; restored within a state park) is 11 miles (18 km) to the west. Inc. town, 1897; city, 1913. Pop. (1990) 2,591; (2000) 2,395.
