The Western United States, commonly referred to as the American West or simply "the West," traditionally refers to the region comprising the westernmost states of the United States. Because the U.S. expanded westward after its founding, the meaning of the West has evolved over time. Prior to about 1800, the crest of the Appalachian Mountains was seen as the western frontier. Since then, the frontier moved further west and the Mississippi River was referenced as the easternmost possible boundary of The West.
In the 21st century, the states including the Rocky Mountains to the West Coast are generally considered to comprise the American West.
In its most expansive definition, the western U.S. is the largest region, covering more than half the land area of the United States. It is also the most geographically diverse, incorporating geographic regions such as the Pacific Coast, the temperate rain forests of the Northwest, the Rocky Mountains, the Great Plains, most of the tall-grass prairie eastward to Western Wisconsin, Illinois, the western Ozark plateau, the western portions of the southern forests, the Gulf Coast, and all of the desert areas located in the United States (the Mojave, Sonoran, Great Basin, and Chihuahua deserts).
The region encompasses some of the Louisiana Purchase, most of the land ceded by Britain in 1818, some of the land acquired when the Republic of Texas joined the U.S., all of the land ceded by Britain in 1846, all of the land ceded by Mexico in 1848, and all of the Gadsden Purchase.
Arizona and New Mexico are always considered to be in the Southwest while portions of California, Colorado, Nevada, Oklahoma, Texas, and Utah are sometimes considered part of the Southwest, while all or part of Idaho, Montana, Oregon, Washington, and Wyoming can be considered part of the Northwest, more narrowly part or all of those same states, with the exception of Wyoming and the eastern portions of Montana and Idaho, and the addition of the Canadian province of British Columbia comprise the Pacific Northwest.
The West can be divided into the Pacific States; Alaska, California, Hawaii, Oregon, and Washington, with the term West Coast usually restricted to just California, Oregon, and Washington, and the Mountain States, always Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming. Alaska and Hawaii, being detached from the other western states, have few similarities with them, but are usually also classified as part of the West. Western Texas in the Chihuahuan Desert is also traditionally considered part of the Western U.S.
Some western states are grouped into regions with eastern states. Kansas, Nebraska, South Dakota and North Dakota are often included in the Midwest, which also includes states like Iowa, Illinois and Wisconsin. Texas, Arkansas, and Louisiana—and to a lesser extent, Oklahoma—are also considered part of the South.
It is rare for any state east of the Mississippi River to be considered part of the modern west. Historically, however, the Northwest Territory was an important early territory of the U.S., comprising the modern states of Ohio, Indiana, Illinois, Michigan and Wisconsin, as well as the northeastern part of Minnesota.
Along the Pacific Ocean coast lie the Coast Ranges, which, while not approaching the scale of the Rockies, are formidable nevertheless. They collect a large part of the airborne moisture moving in from the ocean. Even in the relatively arid climate of central California, the Coast Ranges squeeze enough water out of the clouds to support the growth of coast redwoods. East of the Coast Ranges lie several cultivated fertile valleys, notably the San Joaquin Valley of California and the Willamette Valley of Oregon.
Beyond the valleys lie the Sierra Nevada in the south and the Cascade Range in the north. These mountains are some of the highest in the United States. Mount Whitney, at 14,505 feet (4,421 m) the tallest peak in the contiguous 48 states, is in the Sierra Nevada. The Cascades are also volcanic. Mount Rainier, a volcano in Washington, is also well over 14,000 feet (4,250 meters approx.). Mount St. Helens, a volcano in the Cascades erupted explosively in 1980. A major volcanic eruption at Mount Mazama around 4860 BCE formed Crater Lake. These mountain ranges see heavy precipitation, capturing most of the moisture that remains after the Coast Ranges, and creating a rain shadow to the east forming vast stretches of arid land. These dry areas encompass much of Nevada, Utah and Arizona. The Mojave Desert and Sonoran Desert along with other deserts are found here.
Beyond the deserts lie the Rocky Mountains. In the north, they run almost immediately east of the Cascade Range, so that the desert region is only a few miles wide by the time one reaches the Canadian border. The Rockies are hundreds of miles wide, and run uninterrupted from New Mexico to Alaska. The tallest peaks of the Rockies, some of which are over 14,000 feet (4,250 meters approx.), are found in central Colorado.
The West has several long rivers that empty into the Pacific Ocean, while the eastern rivers run into the Gulf of Mexico. The Mississippi River forms the easternmost possible boundary for the West today. The Missouri River, a tributary of the Mississippi, flows from its headwaters in the Rocky Mountains eastward across the Great Plains, a vast grassy plateau, before sloping gradually down to the forests and hence to the Mississippi. The Colorado River snakes through the Mountain states, at one point forming the Grand Canyon. The Colorado is a major source of water in the Southwest and many dams, such as the Hoover Dam, form reservoirs along it. So much water is drawn for drinking water throughout the West and irrigation in California that in some years, water from the Colorado no longer reaches the Gulf of California. The Columbia River, the largest river in volume flowing into the Pacific Ocean from North America, and its tributary, the Snake River, water the Pacific Northwest. The Platte runs through Nebraska and was known for being a mile (2 km) wide but only a half-inch (1 cm) deep. The Rio Grande forms the border between Texas and Mexico before turning due north and splitting New Mexico in half.
According to the United States Coast Guard, "The Western Rivers System consists of the Mississippi, Ohio, Missouri, Illinois, Tennessee, Cumberland, Arkansas and White Rivers and their tributaries, and certain other rivers that flow towards the Gulf of Mexico".
Facing both the Pacific Ocean and the Mexican border, the West has been shaped by a variety of ethnic groups. Hawaii is the only state in the union in which Asian Americans outnumber European American residents. Asians from many countries have settled in California and other coastal states in several waves of immigration since the 1800s, contributing to the Gold Rush, the building of the transcontinental railroad, agriculture, and more recently, high technology.
The southwestern border states – California, Arizona, New Mexico, and Texas – all have large Mexican American populations, and the many Spanish place names attest to their history as former Mexican territories.
The West also contains much of the Native American population in the U.S., particularly in the large reservations in the mountain and desert states.
Because of having once been a Southern slave state, Texas has a sizeable, non-migrant and rural, African-American population, particularly in the eastern half.
Alaska – the northernmost state in the Union – is a vast land of few, but hearty, people, many of them native, and of great stretches of wilderness, protected in national parks and wildlife refuges. Hawaii's location makes it a major gateway between the U.S. and Asia, as well as a center for tourism.
In the Pacific Coast states, the wide areas filled with small towns, farms, and forests are supplemented by a few big port cities which have evolved into world centers for the media and technology industries. Now the second largest city in the nation, Los Angeles is best known as the home of the Hollywood film industry; the area around Los Angeles also was a major center for the aerospace industry by World War II, though Boeing, located in Washington state would lead the aerospace industry. Fueled by the growth of Los Angeles – as well as the San Francisco Bay Area, including Silicon Valley – California has become the most populous of all the states. Oregon and Washington have also seen rapid growth with the rise of Boeing and Microsoft along with agriculture and resource based industries. The desert and mountain states have relatively low population densities, and developed as ranching and mining areas which are only recently becoming urbanized. Most of them have highly individualistic cultures, and have worked to balance the interests of urban development, recreation, and the environment.
Culturally distinctive points include the large Mormon population of Southeastern Idaho, Utah, Northern Arizona and Nevada; the extravagant casino resort towns of Las Vegas and Reno, Nevada; and, of course, the many Native American tribal reservations.
