Float Copper (Butchite) Nugget 8

Description

Float and Drift Copper is found throughout the “Copper Country” of Michigan. 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 with a bright green color. These specimens with the natural oxidation color provide a great contrast to the polished copper sections. These are excellent glacial float and drift collector specimens from the upper peninsula of Michigan!
This specimen weighs 37.5 oz or 2.34 lbs. (1.063kg) and measures 5.8 x 5.4 x 0.98 inches (14.9 x 13.8 x 2.5 cm)
