Landscape

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.

The Grand Canyon
One of the Seven Natural Wonders of the World, the Grand Canyon dominates the Northern Arizona landscape. Stretching 277 miles across the high plateaus and plunging up to 6,000 feet into the arid plateau, the canyon was shaped and carved by the constant motion of the Colorado River. The Grand Canyon features three or four eras of geological time as well several layers of fossil records, several variety rock types, numerous caves and several major ecosystems.

Climate

A primary reason for travelers to visit to Arizona, specifically in the low desert regions around Phoenix and Tucson, is the state's mild climate during the fall, winter and spring. The warm weather and low precipitation provide travelers with an enjoyable climate for numerous outdoor activities such as hiking, biking, golf and sightseeing. At higher elevations during the winter, snowfall allows visitors to enjoy winter sports such as cross-country skiing.

During the summer months, temperatures in the low desert regions can reach well above 100 degrees F, however the climate at higher elevations, as in Flagstaff, stays mild and allows for enjoyable outdoor activities as well as a break from the summer heat.

Temperatures

High temperatures near or above 100-110 degrees F are common throughout the summer months at the lower elevations. During the winter, cold fronts can bring temperatures well below zero in the higher areas of central and northern Arizona, with lows averaging between 15...
