Americans have long regarded the West as the last frontier. Yet California has a history of European settlement older than that of most midwestern states. Spanish priests founded missions along the California coast a few years before the outbreak of the American Revolution. In the 19th century, California and Oregon entered the Union ahead of many states to the east.

The West is a region of scenic beauty on a grand scale. All of its states are partly mountainous, and the ranges are the sources of startling contrasts. To the west of the peaks, winds from the Pacific Ocean carry enough moisture to keep the land well-watered. To the east, however, the land is very dry. Parts of western Washington State, for example, receive 20 times the amount of rain that falls on the eastern side of the state's Cascade Range.

In much of the West the population is sparse, and the federal government owns and manages millions of hectares of undeveloped land. Americans use these areas for recreational and commercial activities, such as fishing, camping, hiking, boating, grazing, lumbering, and mining. In recent years some local residents who earn their livelihoods on federal land have come into conflict with the land's managers, who are required to keep land use within environmentally acceptable limits.

Alaska, the northernmost state in the Union, is a vast land of few, but hardy, people and great stretches of wilderness, protected in national parks and wildlife refuges. Hawaii is the only state in the union in which Asian Americans outnumber residents of European stock. Beginning in the 1980s large numbers of Asians have also settled in California, mainly around Los Angeles.

Los Angeles -- and Southern California as a whole -- bears the stamp of its large Mexican-American population. Now the second largest city in the nation, Los Angeles is best known as the home of the Hollywood film industry. Fueled by the growth of Los Angeles and the �Silicon Valley� area near San Jose, California has become the most populous of all the states.

Western cities are known for their tolerance. Perhaps because so many westerners have moved there from other regions to make a new start, as a rule interpersonal relations are marked by a live-and-let-live attitude. The western economy is varied. California, for example, is both an agricultural state and a high-technology manufacturing state.
