An exceptionally well-crystallized copper specimen from the historically important copper mining province of the Keweenaw Peninsula, Michigan. While copper mining in Michigan originated thousands of years earlier with Native Americans, modern copper mining in Michigan became an important industry in the 19th and early 20th centuries. The first mineral boom in the United States occurred in 1843 when people from all over the continent began to chase the copper, silver and iron of Michigan's upper peninsula. These mines were in commercial operation for more than a hundred years. Michigan has produced over 14 billion pounds of copper since mining began in 1844. This fantastic specimen of naturally crystallized copper features "fans" of branching, dendritic copper crystals and spinel-law twinned copper crystals. Dimensions (cm): 8 H x 12.5 W x 11.5 D. Location: Keweenaw Peninsula, Michigan, USA HWAC# 53027
