Arizona is a landlocked state in the Southwestern United States , sharing the Four Corners region with Colorado , New Mexico , and Utah . It also borders Nevada to the northwest and California to the west, and shares an international border with the Mexican states of Sonora and Baja California to the south and southwest. Its capital and largest city is Phoenix , which is the most populous state capital and fifth-most populous city in the United States. Arizona is divided into 15 counties .
Arizona is the sixth-largest state by area and the 14th-most-populous of the 50 states. It is the 48th state and last of the contiguous states to be admitted to the Union , achieving statehood on February 14, 1912. Historically part of the territory of Alta California and Nuevo México in New Spain (Spanish Empire ), it became part of independent Mexico in 1821. After being defeated in the Mexican–American War , Mexico ceded much of this territory to the United States in 1848, where the area became part of the New Mexico Territory . The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase .
Southern Arizona is known for its desert climate, with extremely hot summers and mild winters. Northern Arizona features forests of pine, Douglas fir , and spruce trees; the Colorado Plateau ; mountain ranges (such as the San Francisco Mountains ); as well as large, deep canyons , with much more moderate summer temperatures and significant winter snowfalls. There are ski resorts in the areas of Flagstaff , Sunrise , and Tucson . In addition to the internationally known Grand Canyon National Park , which is one of the world's seven natural wonders , there are several national forests , national parks , and national monuments .
Arizona is home to a diverse population. About one-quarter of the state is made up of Indian reservations that serve as the home of 27 federally recognized Native American tribes , including the Navajo Nation , the largest in the state and the country, with more than 300,000 citizens. Since the 1980s, the proportion of Hispanics has grown significantly owing to migration from Mexico and Central America. A substantial portion of the population are followers of the Roman Catholic Church and the Church of Jesus Christ of Latter-day Saints . Arizona's population and economy have grown dramatically since the 1950s because of inward migration, and the state is now a major hub of the Sun Belt . Many large companies, such as PetSmart and Circle K , have headquarters in the state, and Arizona is home to major universities, including the University of Arizona , Arizona State University , and Northern Arizona University .

Waterfall on Fossil Creek
Fossil Creek (Yavapai : Hakhavsuwa or Vialnyucha ) is a perennial stream accessed by a forest road near the community of Camp Verde in the U.S. state of Arizona . Access is from Forest Road 708 off Arizona State Route 260 east of Camp Verde. A tributary of the Verde River , Fossil Creek flows from its headwaters on the Mogollon Rim to meet the larger stream near the former Childs Power Plant .
Fossil Springs , near the headwaters, emits upwards of 20,000 US gallons (76 m3 ) per minute that flow into the creek year-round. Calcium carbonate , precipitating from the 72 °F (22 °C) water from the springs, creates travertine dams and deposits for several miles downstream. The Fossil Creek system is the fourth largest producer of travertine in the United States. (Full article... )
Havasu Falls
Havasu Falls , one of the four waterfalls of the Havasupai Indian Reservation, is located near the village of Supai, Arizona . It is the second of four falls on Havasu Creek, which empties into the Grand Canyon on the Colorado River . The water of Havasu Creek has a bluish green tint due to the heavy lime content of the water. The fall is forked and looks like two falls when the river is flowing heavily.
