I also went to the Petrified Forest that contains the remains of the Triassic Period. Basically, the area flooded all of the trees and carried them through the land and covered them with sediment for millions of years, that sediment is made up of agate, amethyst, and other gemstones. So, when mountains lifted and erosion occurred they were exposed. They look like multicolored gemstone discs encased in bark. They are incredible!
No, I did not steal any. I read the sign and followed the rules :)
