In the United States, a state is a constituent political entity, of which there are currently 50. Bound together in a political union, each state holds governmental jurisdiction over a separate and defined geographic territory and shares its sovereignty with the federal government. Due to this shared sovereignty, Americans are citizens both of the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons restricted by certain types of court orders. Four states use the term commonwealth rather than state in their full official names.
Arizona is a state in the southwestern region of the United States. It is also part of the Western and the Mountain states. It is the sixth largest and the 14th most populous of the 50 states.

The Four Corners is a region of the United States consisting of the southwestern corner of Colorado, southeastern corner of Utah, northeastern corner of Arizona, and northwestern corner of New Mexico. The Four Corners area is named after the quadripoint at the intersection of approximately 37° north latitude with 109° 03' west longitude, where the boundaries of the four states meet, and are marked by the Four Corners Monument. It is the only location in the United States where four states meet. Most of the Four Corners region belongs to semi-autonomous Native American nations, the largest of which is the Navajo Nation, followed by Hopi, Ute, and Zuni tribal reserves and nations. The Four Corners region is part of a larger region known as the Colorado Plateau and is mostly rural, rugged, and arid. In addition to the monument, commonly visited areas within Four Corners include Monument Valley, Mesa Verde National Park, Chaco Canyon, Canyons of the Ancients National Monument and Canyon de Chelly National Monument. The most populous city in the Four Corners region is Farmington, New Mexico, followed by Durango, Colorado.
Abert's squirrel, or tassel-eared squirrel, is a tree squirrel in the genus Sciurus native to the southern Rocky Mountains from the United States to the northern Sierra Madre Occidental of Mexico, with concentrations found in Arizona, the Grand Canyon, New Mexico, and southwestern Colorado. It is closely associated with, and largely confined to, cool dry ponderosa pine forests. It is named in honor of the American naturalist John James Abert; nine subspecies are recognised. It is recognizable by its tufted ears, gray color, pale underparts and rufous patch on the lower back. The squirrel feeds on the seeds and cones of the Mexican pinyon and the ponderosa pine when they are available, but will also take fungi, buds, bark, and carrion. Breeding normally occurs in summer, with a spherical nest being built high in the canopy.
The Africanized bee, also known as the Africanised honey bee, and known colloquially as the "killer bee", is a hybrid of the western honey bee species, produced originally by cross-breeding of the East African lowland honey bee (A. m. scutellata) with various European honey bees such as the Italian honey bee A. m. ligustica and the Iberian honey bee A. m. iberiensis.

The Southwestern United States, also known as the American Southwest, is the informal name for a region of the western United States. Definitions of the region's boundaries vary a great deal and have never been standardized, though many boundaries have been proposed. For example, one definition includes the stretch from the Mojave Desert in California to Carlsbad, New Mexico, and from the Mexico–United States border to the southern areas of Colorado, Utah, and Nevada. The largest metropolitan areas are centered around Phoenix, Las Vegas, Tucson, Albuquerque, and El Paso. Those five metropolitan areas have an estimated total population of more than 9.6 million as of 2017, with nearly 60 percent of them living in the two Arizona cities—Phoenix and Tucson.
The Sonoran Desert is a North American desert which covers large parts of the Southwestern United States in Arizona and California and of Northwestern Mexico in Sonora, Baja California, and Baja California Sur. It is the hottest desert in Mexico. It has an area of 260,000 square kilometers (100,000 sq mi). The western portion of the United States–Mexico border passes through the Sonoran Desert.
The Gila River is a 649-mile (1,044 km) tributary of the Colorado River flowing through New Mexico and Arizona in the United States. The river drains an arid watershed of nearly 60,000 square miles (160,000 km2) that lies mainly within the U.S. but also extends into northern Sonora, Mexico. Indigenous peoples have lived along the river for at least 2,000 years, establishing complex agricultural societies before European exploration of the region began in the 16th century. However, European Americans did not permanently settle the Gila River watershed until the mid-19th century.
The Salt River is a stream in the U.S. state of Arizona. It is the largest tributary of the Gila River. The river is about 200 miles (320 km) long. Its drainage basin is about 13,700 square miles (35,000 km2) large. The longest of the Salt River's many tributaries is the 195-mile (314 km) Verde River. The Salt's headwaters tributaries, the Black River and East Fork, increase the river's total length to about 300 miles (480 km). The name Salt River comes from the fact that the river flows over large salt deposits shortly after the merging of the White and Black Rivers.
The Apache-Sitgreaves National Forests are two 2.76-million-acre (11,169 km2) United States National Forests which run along the Mogollon Rim and the White Mountains in east-central Arizona and into the U.S. state of New Mexico. Both forests are managed as one unit by USDA Forest Service from the forests Supervisors Office in Springerville, Arizona. Apache-Sitgreaves has over 400 species of wildlife. With its high elevation and cool summer breezes it is a popular weekend destination from the hot desert for Phoenix, Arizona residents. The forest is divided into 5 Ranger Districts that span almost 300 miles (480 km) from Clifton, Arizona in the east-central portion of Arizona to the eastern boundary of the Coconino National Forest in north-central Arizona. The Apache-Sitgreaves National Forest borders the western and northern borders of the Fort Apache Indian Reservation. It is located in parts of Greenlee, Apache, Navajo, and Coconino counties in eastern and east-central Arizona, and Catron County in western New Mexico. The more northwesterly Sitgreaves National Forest portion lies adjacent to the north side of the Fort Apache Indian Reservation and is located entirely in Arizona, within Navajo, Apache, and Coconino counties. It has a total area of 818,651 acres (3,313 km2). The more southeasterly and much larger Apache National Forest portion lies adjacent to the east side of the Fort Apache and the San Carlos Indian Reservations. It lies on both sides of the border with New Mexico, in Greenlee, Catron, and Apache counties. It has a total area of 1,813,601 acres (7,339 km2).

The Yuma Desert is a lower-elevation section of the Sonoran Desert in the southwestern United States and the northwest of Mexico. It lies in the Salton basin. The desert contains areas of sparse vegetation and has notable areas of sand dunes. With an average rainfall less than 8 inches (200 mm) each year, this is among the harshest deserts in North America. Human presence is sparse throughout, the largest city being Yuma, Arizona, on the Colorado River and the border of California.
Tonto National Monument is a National Monument in the Superstition Mountains, in Gila County of central Arizona. The area lies on the northeastern edge of the Sonoran Desert ecoregion, an arid habitat with annual rainfall of about 16 inches (400 mm) here. The Salt River runs through this area, providing a rare, year-round source of water.
The Lower Colorado River Valley ("LCRV") is the river region of the lower Colorado River of the southwestern United States in North America that rises in the Rocky Mountains and has its outlet at the Colorado River Delta in the northern Gulf of California in northwestern Mexico, between the states of Baja California and Sonora. This north–south stretch of the Colorado River forms the border between the U.S. states of California/Arizona and Nevada/Arizona, and between the Mexican states of Baja California/Sonora.
Arizona is a landlocked state situated in the southwestern region of the United States of America.
