Why are you reporting this puzzle?
While the colors in this photo did not turn out nearly as well as some of the others, the structure is so beautiful, it is still one of my favorites. All the minerals I photographed - with the exception of the gypsum - are large, however this piece of copper was the biggest. I didn't estimate its size when I was there so this is a guess: maybe 18" (45 cm) across? Could have been a little bigger or smaller. If anyone else has seen it and can remember if I'm grossly exaggerating, please let me know in the comments.
