Southwestern United States

The Southwestern United States (also known as the American Southwest) is the United States portion of the Southwest (which is situated in both the United States and Mexico). It is a region of the United States defined in different ways by different sources. The definition of what constitutes the American Southwest has evolved over the last one hundred and fifty years, moving steadily farther south and west, as well as becoming more confined in scope. Broad definitions have included nearly a quarter of the United States, including Arizona, California, Colorado, Nevada, New Mexico, Oklahoma, Texas, and Utah. Narrowly defined, the "core" Southwest is centered on Arizona and western New Mexico, the extreme western part of Texas, and the very southern parts of Colorado and Utah. This is one of the most common definitions of the term, as exemplified by archeologists such as Erik Reed and geologists such as D. W. Meinig. The other variations are discussed in a separate section, the main article will deal with this core definition, which includes all of Arizona, the western portion of New Mexico, bordered on the east by the Llano Estacado, the southern portions of Colorado and Utah below the 39th parallel, the "horn" of Texas (the Trans-Pecos section, below New Mexico, which includes El Paso), the southernmost triangle of Nevada, and the very most southeastern portion of California, which encompasses the Mojave and Colorado Deserts.

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.
