Keweenaw National Historical Park - Calumet Unit

Calumet Unit

The Calumet Unit of the Keweenaw National Historical Park includes many sites in and around the villages of Calumet and Laurium, which are not ghost towns but operating human communities that have survived the shutdown of their parent employer, the Calumet and Hecla Mining Company, in 1968. By digging shafts into the rock, the men and owners of the Calumet & Hecla found geological formations of rock laced with nuggets of almost pure copper.

The Calumet & Hecla was the richest of the separate copper mines of the Keweenaw, and the towns built at the mine head reflect its productivity. A 1,200-seat opera house, large churches built of Lake Superior brownstone, and mansions built by the mining bosses survive as memories of the Calumet mine's glory years.

Famous quotes containing the word unit:

    During the Suffragette revolt of 1913 I ... [urged] that what was needed was not the vote, but a constitutional amendment enacting that all representative bodies shall consist of women and men in equal numbers, whether elected or nominated or coopted or registered or picked up in the street like a coroner’s jury. In the case of elected bodies the only way of effecting this is by the Coupled Vote. The representative unit must not be a man or a woman but a man and a woman.
    George Bernard Shaw (1856–1950)
