Mississippi Petrified Forest

Mississippi Petrified Forest is a petrified forest located near Flora, Mississippi in the United States. It is currently privately owned and open for public visitation. The forest is believed to have been formed 36 million years ago when fir and maple logs washed down an ancient river channel to the current site where they later became petrified. It is the only petrified forest in the eastern United States. It was declared a National Natural Landmark in October 1965.^[2][3]
