Visit Arizona - Arizona is one of the most diverse state in terms of scenic beauty and landscape. This makes Arizona one of the most popular states for RVing and sightseeing.
Arizona covers 113,909 square miles, with about 350 square miles of water surface including Lake Havasu, Lake Powell, Lake Mead and the Colorado River. The state consists of three primary topographical features: a high plateau in the northeast of the state, averaging between 5,000 and 7,000 feet in elevation; a mountainous region which runs from the southeast to the northwest with peak elevations between 9,000 and 12,000 feet; and low mountain ranges and desert valleys in the southwestern of the state.The state is defined by the Grand Canyon in the north, the Mogollon (pronounced MUG-ee-own) Rim in the central mountainous region and the Sonoran Desert to the south. Scattered among these regions, features such as the red rocks of Sedona, the tall, wind-swept towers of Monument Valley and the saguaro-filled desert valleys around Phoenix and Tucson add depth and character to the landscape of Arizona.
Another prominent feature of the Arizona landscape, a Ponderosa Pine forest stretches across the state from the White Mountain region around Greer and Alpine across the Mogollon Rim to the San Francisco Peaks north of Flagstaff. This strip of pine also extends beyond the Grand Canyon onto the Kaibab Plateau and into Southern Utah.
Humphreys Peak, part of the San Francisco Peaks, is the highest point in Arizona with an elevation of 12,611 feet. Baldy Peak, located in the White Mountains, is the second highest point with an elevation of 11,490 feet. In the southwest of the state, the Sonoran Desert stretches out of Mexico and into Arizona with elevations as low as about 100 feet above sea level in the Lower Colorado River Valley. Wiki
