The three-needled Rocky Mountain ponderosa pine is the most common pine tree found in Arizona.
Petrified Forest National Park

Petrified forests are the unique attractions enjoyed at Petrified National Park. This national park is located 118 miles east of Flagstaff, off Interstate 40. Enjoy 200-million-year-old fossils and one of the most colorful concentrations of petrified wood, multi-hued badlands and more. This is a remarkable place that provides a glimpse into ancient times.
Saguaro National Park

Located about 16 miles east of Tucson, Saguaro National Park is home to some enormous, towering cacti. Saguaro are only found in a small area of the U. S., and here is one of the impressive displays of the subtropical giants.
