The fallen petrified trees lived in the late Triassic
period about 225 million years ago when northern Arizona was near the equator on the southwestern edge of the super continent
Pangea. The climate was moist, humid subtropical
How interesting. Something I learned about long ago in public school. My brother stopped at the Petrified Forest National Park on his way to visit his son in CA. (I was on the phone with him at the time.) He couldn't throw enough time into the stop to walk to see the trees like this. Is this where you were?
