Arizona (/ˌærɪˈznə/ ARR-ih-ZOH-nə; Navajo: Hoozdo Hahoodzo [hoː˥z̥to˩ ha˩hoː˩tso˩]; O'odham: Alĭ ṣonak [ˈaɭi̥ ˈʂɔnak]) is a landlocked state in the Southwestern region of the United States. It is part of the Four Corners region with Utah to the north, Colorado to the northeast, and New Mexico to the east; its other neighboring states are Nevada to the northwest, California to the west and the Mexican states of Sonora and Baja California to the south and southwest. It is the 6th-largest and the 14th-most-populous of the 50 states. Its capital and largest city is Phoenix, which is the most populous state capital in the United States.

Arizona 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, 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 territory of New Mexico. The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase.

Southern Arizona is known for its desert climate, with very 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. Cities such as Phoenix and Tucson have developed large, sprawling suburban areas. 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. The state is known for a history of conservative politicians such as Barry Goldwater and John McCain, though it has become a swing state since the 1990s. (Full article...)

Hoover Dam by Ansel Adams, 1941

Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. Constructed between 1931 and 1936, during the Great Depression, it was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over 100 lives. In bills passed by Congress during its construction, it was referred to as the Hoover Dam, after President Herbert Hoover, but was named the Boulder Dam by the Roosevelt administration. In 1947, the name Hoover Dam was restored by Congress.

Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water, and produce hydroelectric power. In 1928, Congress authorized the project. The winning bid to build the dam was submitted by a consortium named Six Companies, Inc., which began construction in early 1931. Such a large concrete structure had never been built before, and some of the techniques used were unproven. The torrid summer weather and lack of facilities near the site also presented difficulties. Nevertheless, Six Companies turned the dam over to the federal government on March 1, 1936, more than two years ahead of schedule. (Full article...)

Selected biography - show another

Ruth Elizabeth "Bazy" Tankersley (née McCormick, formerly Miller; March 7, 1921 – February 5, 2013) was an American breeder of Arabian horses and a newspaper publisher. She was a daughter of U.S. Senator Joseph Medill McCormick. Her mother was progressive Republican U.S. Representative Ruth Hanna McCormick, making Tankersley a granddaughter of Senator Mark Hanna of Ohio. Although Tankersley was involved with conservative Republican causes as a young woman, including a friendship with Senator Joseph McCarthy, her progressive roots reemerged in later years. By the 21st century, she had become a strong supporter of environmental causes and backed Barack Obama for president in 2008.

Tankersley's father died when she was a child. When her mother remarried, the family moved to the southwestern United States, where Tankersley spent considerable time riding horses. She became particularly enamored of the Arabian breed after she was given a part-Arabian to ride. At the age of 18, she began working as a reporter for a newspaper published by her mother. She later ran a newspaper in Illinois with her first husband, Peter Miller. In 1949, she became the publisher of the conservative Washington Times-Herald. That paper was owned by her uncle, the childless Robert McCormick, who viewed Tankersley as his heir until the two had a falling-out over editorial control of the newspaper and her relationship with Garvin Tankersley, who became her second husband. After The Washington Post absorbed the Times-Herald, she shifted to full-time horse breeding. (Full article...)
