This picture shows the wood grain in one of the logs. The petrified rocks in Arizona have lots of red in them. They're really pretty. We went to a film at the visitor's center before we started our tour. We learned that the trees started out in a huge swamp and were submerged in water and eventually covered with silt (and then dirt, rocks, etc. when the swamp dried up). All the debris covering them preserved them for us to see now!
This is a log field! Lots of really big logs that we got to walk through. It was really neat to walk through so many rock logs! This was a neat place to visit.
