Arizona copper ore

with 38 comments

On November 7th last year I couldn’t help noticing that the people who run the Arizona-Sonora Desert Museum in Tucson have placed some colorful slabs of copper ore at the entrance to their establishment. An accompanying sign says: “These boulders were mined south of Tucson. They are rich in copper minerals: the blue-green is chrysocolla, the blue is azurite, and the green is malachite.”

To take this picture I lay on the ground and aimed at an angle elevated enough to include some of the day’s fleecy clouds.
