Defining the West

The Western U.S. is the largest region of the country, covering nearly half the land area of the contiguous United States. It is also the most geographically diverse, incorporating geographic regions such as the temperate rainforests of the Northwest, the highest mountain ranges (including the
Rocky Mountains The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico ...
, the Sierra Nevada, and the Cascade Range), numerous glaciers, and the western edge of the Great Plains. It also contains the majority of the desert areas located in the United States. The Mojave and Great Basin 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 Great Plains or on the
Mississippi River The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it fl ...
. The survey respondents as a whole showed just how little agreement there was on the boundaries of the West.

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.

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.
