Featured in this lot are three pieces of Michigan Native "Float" Copper found in the Copper County of Michigan. Butchite, usually known as Float Copper, is found in abundance in the state of Michigan. In geology, "float" is a term that refers to any material that has been carried away by erosion from where it was formed. Glacial movements thousands of years ago altered the geologic deposits of the native copper by tearing and scouring the land. Copper, along with other rocks, gravel, and sand were constantly tumbled and deposited over large areas of the Upper Midwestern United States. Exposure to the soils, water and air has oxidized the copper surface to a bright green. The float copper pieces show bright copper colors and other sediments set in the pieces with one piece showing small crystals. The largest float copper piece measures 2 1/2" L x 1 1/2" W x 3/4" H, while the smallest measures 1 1/2" L x 1" W x 13/16" H.
