The sky finally got dark and we got our first look at the large rock piles called mine dumps. Under short-wave ultraviolet the ordinary looking rocks were wonderfully colorful, glowing in fantastic combinations of red, yellow and blue. Sometimes there was white and a few other colors mixed in.

Most of them were small but a few that I found were large museum-quality pieces. The Long Lake Zinc Mine specimens are uniquely beautiful. I know of no other location in the world that has fluorescent minerals like these.
