In political theory, sovereignty is a substantive term designating supreme authority over some polity. It is a basic principle underlying the dominant Westphalian model of state foundation.  - California is the most populous state in the United States and the third most extensive by area. Located on the western (Pacific Ocean) coast of the U.S., California is bordered by the other U.S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. The state capital is Sacramento. Los Angeles is California's most populous city, and the country's second largest after New York City. The state also has the nation's most populous county, Los Angeles County, and its largest county by area, San Bernardino County.  - A U.S. state is a constituent political entity of the United States of America. There are 50 states, which are bound together in a union with each other. Each state holds administrative jurisdiction over a defined geographic territory, and shares its sovereignty with the United States federal government. Due to the shared sovereignty between each state and the federal government, Americans are citizens of both 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 covered by certain types of court orders (e.g., paroled convicts and children of divorced spouses who are sharing custody).  - Nevada (Spanish for "snowy"; see pronunciations) is a state in the Western, Mountain West, and Southwestern regions of the United States of America. Nevada is the 7th most extensive, the 34th most populous, and the 9th least densely populated of the 50 United States. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las VegasParadise metropolitan area where three of the state's four largest incorporated cities are located. Nevada's capital is Carson City. Nevada is officially known as the "Silver State" because of the importance of silver to its history and economy. It is also known as the "Battle Born State", because it achieved statehood during the Civil War (the words "Battle Born" also appear on the state flag); as the "Sage-brush State", for the native plant of the same name; and as the "Sage-hen State". Nevada borders Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast and Utah to the east.  - Utah (or ) is a state in the western United States. It became the 45th state admitted to the U.S. on January 4, 1896. Utah is the 13th-largest by area, 31st-most-populous, and 10th-least-densely populated of the 50 United States. Utah has a population of more than 3 million (Census estimate for July 1, 2016), approximately 80% of whom live along the Wasatch Front, centering on the state capital Salt Lake City. Utah is bordered by Colorado to the east, Wyoming to the northeast, Idaho to the north, Arizona to the south, and Nevada to the west. It also touches a corner of New Mexico in the southeast.  - A federal republic is a federation of states with a republican form of government. At its core, the literal meaning of the word republic when used to reference a form of government means: "a country that is governed by elected representatives and by an elected leader (such as a president) rather than by a king or queen".  - Las Vegas (Spanish for "The Meadows"), officially the City of Las Vegas and often known simply as Vegas, is the 28th-most populated city in the United States, the most populated city in the state of Nevada, and the county seat of Clark County.

Arizona's border with Mexico is 389 miles (626 km) long, on the northern border of the Mexican states of Sonora and Baja California.  - Hiko is a small, agrarian community in the Tonopah Basin on State Route 318 in Lincoln County, Nevada, United States. It is a census-designated place, with a population of 119 at the 2010 census. Hiko was the county seat of Lincoln County from 1867 to 1871 and a few hundred residents lived nearby, due largely to silver mines in the area. Today, the area is a farming and ranching area, and not much remains of the old town except the cemetery, some mill ruins and a red rock building that was a general store. Although populated, Hiko appears on at least two ghost town lists. Most of the residents of Hiko own farms or ranches, and little to no industrial activity takes place there. In 1871 Hiko was replaced as the county seat of Lincoln County with the current seat, Pioche.  - City is a piece of earth art located in Garden Valley , a desert valley in rural Lincoln County in the U.S. state of Nevada , near the border with Nye County .

As a result, Americans do not equate their nationality with ethnicity, but with citizenship and allegiance. Although citizens make up the majority of Americans, non-citizen residents, dual citizens, and expatriates may also claim an American identity.  - Land art, earthworks (coined by Robert Smithson), or Earth art is an art movement in which landscape and the work of art are inextricably linked. It is also an art form that is created in nature, using natural materials such as soil, rock (bed rock, boulders, stones), organic media (logs, branches, leaves), and water with introduced materials such as concrete, metal, asphalt, or mineral pigments. Sculptures are not placed in the landscape, rather, the landscape is the means of their creation. Often earth moving equipment is involved. The works frequently exist in the open, located well away from civilization, left to change and erode under natural conditions. Many of the first works, created in the deserts of Nevada, New Mexico, Utah or Arizona were ephemeral in nature and now only exist as video recordings or photographic documents. They also pioneered a category of art called site-specific sculpture, designed for a particular outdoor location.
