Arizona

Arizona (ⁱ/ɛrɪˈzoʊnə/; /ærɪˈzoʊnə/) (Navajo: Hoozdo Hahoodzo; O'odham: Alĭ ṣonak) is a state in the southwestern region of the United States. It is also part of the Western United States and of the Mountain West states. It is the sixth largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona is one of the Four Corners states. It has borders with New Mexico, Utah, Nevada, California, and Mexico, and one point in common with the southwestern corner of Colorado. Arizona's border with Mexico is 389 miles (626 km) long, on the northern border of the Mexican states of Sonora and Baja California.

Arizona is the 48th state and last of the contiguous states to be admitted to the Union, achieving statehood on February 14, 1912. It was previously part of the territory of Alta California in New Spain before being passed down to independent Mexico and later ceded to the United States after the Mexican–American War. The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase.

Grand Canyon

The Grand Canyon (Hopi: Ongtupqa; Yavapai: Wi:kaʼi:la, Spanish: Gran Cañón) is a steep-sided canyon carved by the Colorado River in the state of Arizona in the United States. It is contained within and managed by Grand Canyon National Park, the Kaibab National Forest, Grand Canyon-Parashant National Monument, the Hualapai Tribal Nation, the Havasupai people and the Navajo Nation. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery.

The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters). Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While some aspects about the history of incision of the canyon are debated by geologists, several recent studies support the hypothesis that the Colorado River established its course through the area about 5 or 6 million years ago. Since that time, the Colorado River has driven the down-cutting of the tributaries and retreat of the cliffs, simultaneously deepening and widening the canyon.

National park

A national park is a park in use for conservation purposes. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride. An international organization, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas, has defined "National Park" as its Category II type of protected areas.

While this type of national park had been proposed previously, the United States established the first "public park or pleasuring-ground for the benefit and enjoyment of the people", Yellowstone National Park, in 1872. Although Yellowstone was not officially termed a "national park" in its establishing law, it was always termed such in practice and is widely held to be the first and oldest national park in the world. The first area to use "national park" in its creation legislation was the US's Mackinac Island, in 1875. Australia's Royal National Park, established in 1879, was the world's third official national park. In 1895 ownership of Mackinac Island was transferred to the State of Michigan as a state park and national park status was consequently lost. As a result, Australia's Royal National Park is by some considerations the second oldest national park now in existence.

Tourism

Tourism is travel for pleasure; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. Tourism may be international, or within the traveler's country. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only ", as people "traveling to and staying in places outside their usual environment for not more than one consecutive year for leisure, business and other purposes".

Tourism can be domestic or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Today, tourism is a major source of income for many countries, and affects the economy of both the source and host countries, in some cases being of vital importance.

Tourism suffered as a result of a strong economic slowdown of the late-2000s recession, between the second half of 2008 and the end of 2009, and the outbreak of the H1N1 influenza virus, but slowly recovered. International tourism receipts (the travel item in the balance of payments) grew to US$1.03 trillion (€740 billion) in 2011, corresponding to an increase in real terms of 3.8% from 2010. International tourist arrivals surpassed the milestone of 1 billion tourists globally for the first time in 2012, the same year in which China became the largest spender in international tourism globally with US$102 billion, surpassing Germany and United States. China and emerging markets such as Russia and Brazil had significantly increased their spending over the previous decade.

Saguaro National Park

Saguaro National Park is located in southern Arizona on the outskirts of Tucson and is a part of the United States National Park System. The park preserves the desert landscape, fauna and flora contained within two park sections, one east and the other west of Tucson. The park was established to protect its namesake—the giant saguaro cactus (Carnegiea gigantea). Saguaro in this park are near the northernmost limit of their natural survival zone within the Sonoran Desert.

Overview

The park is divided into two sections, called districts, lying approximately 20 miles (32 km) east and 15 miles (24 km) west of the center of the city of Tucson, Arizona. The total area in 2011 was 91,442 acres (37,005 ha) of which 70,905 acres (28,694 ha) is designated wilderness. There is a visitor center in each of the two districts. Both are easily reached by car from Tucson, but there is no public transport into the park. Both districts conserve fine tracts of the Sonoran Desert, including ranges of significant hills, the Tucson Mountains in the west and the Rincon Mountains in the east. The park gets its name from the saguaro, a large cactus which is native to the region. Many other kinds of cactus, including barrel, cholla, and prickly pear, are abundant in the park. One endangered animal, the lesser long-nosed bat, lives in the park part of the year during its migration, together with one threatened species, the Mexican spotted owl.
