There are in fact fossils found at the Grand Canyon National Park. But here's the fun part, they are older than any known dinosaur dating back to 1200 to 740 million years ago. It is illegal to take any of the fossils from the park if you find them. You must leave them there for other visitors to enjoy and scientists to study. Also, it is a great place to study climate changes, ancient environments, life zones and processes that formed the Grand Canyon the way we see it today.


There is, or was in fact volcanic activity in the Grand Canyon at one point. Now the most you get is a rock falling or on rare occasion you may get a landslide. Over 2 million years there has been hundreds of volcanic eruptions. There's 3 massive lava dams standing at over 1000 feet tall forming lakes 100 miles long that you used to be able to see before the dams eroded it away.
