The Petrified Forest also has the Painted Desert, petroglyphs, fossils, ancient pueblos, and ancient pottery and arrow-heads. In 1895 the Arizona Territorial legislature petitioned Congress to protect this valuable scientific and cultural treasure. In 1906, President Theodor Roosevelt signed legislation creating Petrified Forest National Monument. The monument became a national park in 1962.
The petroglyphs capture thousands of years of the human story. Although we do not know the meaning of all the petroglyphs, several are solar calendars. Some mark the summer or winter solstice, while others indicate both equinoxes.
