Defining the West

deserts lie entirely within the Western region, along with parts of the Sonoran and Chihuahuan deserts (the latter extends significantly into Texas). Given this expansive and diverse geography it is no wonder the region is difficult to specifically define. Sensing a possible shift in the popular understanding of the West as a region in the early 1990s, historian Walter Nugent conducted a survey of three groups of professionals with ties to the region: a large group of Western historians (187 respondents), and two smaller groups, 25 journalists and publishers and 39 Western authors. A majority of the historian respondents placed the eastern boundary of the West east of the Census definition out on the eastern edge of the

Climate and agriculture

Most of the public land held by the U.S. National Forest Service and Bureau of Land Management is in the Western states. Public lands account for 25 to 75 percent of the total land area in these states. The climate of the West is semi-arid, yet parts of the region get high amounts of rain or snow. Other parts are true desert which receive less than of rain per year. The climate is unstable, as areas that are normally wet can be very dry for years and vice versa. The seasonal temperatures vary greatly throughout the West. Low elevations on the West Coast have warm summers and mild winters with little to no snow. The

and the Mormon Trail, made its fortunes on outfitting settlers; St. Louis built itself upon the vast fur trade in the West before its settlement. The 1850s were marked by political battles over the expansion of slavery into the western territories, issues leading to the Civil War. Between 1863 and 1869, North America's first transcontinental railroad was constructed to connect the eastern US with the Pacific coast. The resulting railroad connection revolutionized the settlement and economy of the American West by making the transportation of passengers and freight quicker, safer, and cheaper. The history of the American West in the late 19th and early 20th centuries has acquired a cultural mythos in the literature and cinema of the United States. The image of the

created western art as a method of recording the expansion into the west. The American cinema, in particular, created the genre of the western movie, which, in many cases, use the West as a metaphor for the virtue of self-reliance and an American ethos. The contrast between the romanticism of culture about the West and the actuality of the history of the westward expansion has been a theme of late 20th and early 21st century scholarship about the West. Cowboy culture has become embedded in the American experience as a common cultural touchstone, and modern forms as diverse as country and western music have celebrated the sense of isolation and independence of spirit inspired by the frontiersmen on "virgin land".

years as a major watershed, as a region experienced enormous social and economic change, and became the pacesetter for societal evolution. The population soared, especially in metropolitan areas, as a result of massive expansion of the manufacture of airplanes, ships and munitions and of military and Naval training facilities. California upgraded universities to world-class status, intensified scientific research, and expanded infrastructure. After the war millions more migrated using the GI Bill to buy suburban homes, many of them recalling rewarding wartime experience in military training facilities. The region had always been more democratic with greater racial and gender equality, and continued as a national pacesetter in modernization. New problems emerged, especially environmental issues where westerners took the lead in areas such as the allocation of scarce water resources as well as dealing with smog and air pollution. More recently historians have looked at nuances, pointing out that some of the trends began before 1941. Los Angeles has the largest Mexican population outside of
