The Making of a Mining District: Keweenaw Native Copper 1500-1870The Making of a Mining District is the first book to fully document the Keweenaw Peninsula of northern Michigan's large amount of pure metallic "native" state, and the unique value of these deposits. The Keweenaw Peninsula of northern Michigan is the only place on earth where large amounts of copper are found in the pure metallic "native" state. The Making of a Mining District is the first book to fully document how the value of these unique deposits came to be recognized, from the time Europeans first became aware of the native copper shortly after 1500 to the establishment of the region as one of the great copper mining districts of the world. |
