Print of the Superior Stone.
What is the Superior Stone?
The stone was quite different from other banded agates because there were no bands. The face of the stone was open. It had never been cut. Immediately you could clearly see a picture.
In research it was found that the region had volcanic activity 100 million years ago.
Agates are formed from pockets of minerals, and with cooling and pressure bands are formed.
The belief is that this pocket of minerals was exposed when the large meteor hit the earth about 65 million years ago. The resultant explosion was so large that the stone was altered. With the flash and heat a picture was taken naturally of the day the dinosaurs became extinct.
