Pacific Southwest

Last updated

The Pacific Southwest is a region of the United States. In its broadest definition, it encompasses five states: California, Arizona, Hawaii, Utah, and part of Nevada. The region is one of cultural diversity seen all over. Several major urban areas lie within the region, including Salt Lake City. With the exception of Hawaii, four of the five states share similar historical backgrounds.[ citation needed ]

Definition

There is no universally accepted definition of the phrase "Pacific Southwest." Whereas the related term Southwestern United States is generally used in a cultural or historical sense (for example, to refer to parts of the United States that were once part of the First Mexican Empire), the term "Pacific Southwest" is more commonly defined strictly by geographic or ecological factors.

For example, the American Society for Photogrammetry and Remote Sensing has a geographical application of the term, defining it as California, Arizona, Nevada and Hawaii. [1] The Fish and Wildlife Service, on the other hand, uses an ecological approach to define it as California, Nevada, and the Klamath Basin (which includes parts of Oregon). [2]

Ambiguity regarding the term is further compounded by the fact that even several United States federal agencies use different definitions. In addition to the Fish and Wildlife Service mentioned above, the Environmental Protection Agency defines Pacific Southwest as California, Nevada, Arizona and Hawaii, [3] and the Forest Service defines it as California, Hawaii, and other U.S. islands in the Pacific Ocean.

Culture

Cultures combine and collaborate in the Pacific Southwest. Traces of the Old American West can still be seen in some areas, especially in the deserts. Hip-hop is one of the many cultures prevalent here, most noticeable in Los Angeles. Polynesian culture flourishes in Hawaii, and Hawaiian Pidgin can still be heard in certain areas of the state. Spanish/Mexican culture is the most visible in the region, due to four of the five states having once been Spanish/Mexican possessions. Cowboys in the vaquero traditions of northern Mexico can be found in the Pacific Southwest, though less along the Pacific coast. Hawaii has its own version of the American cowboy, the paniolo. Asian culture is demonstrated in the region, especially in California and Hawaii. The area also has a sizeable black population, along with prominent Arabic and Jewish cultures.

Geography

The Pacific Southwest contains a vast diversity in environments. Sub-arctic conditions are common in the high mountains of the region, such as in the Sierra Nevada and on Mauna Kea. California, Nevada, and Arizona contain significant deserts, both hot and cold type. California is characterized primarily by hot summer and warm summer Mediterranean climates, in addition to 33 million acres of forests. Rainforests exist along the northernmost coast of California, as well as in certain areas of Hawaii.

Geography of California Overview of the geography of California

California is a U.S. state on the western coast of North America. Covering an area of 163,696 sq mi (423,970 km2), California is among the most geographically diverse states. The Sierra Nevada, the fertile farmlands of the Central Valley, and the arid Mojave Desert of the south are some of the major geographic features of this U.S. state. It is home to some of the world's most exceptional trees: the tallest, most massive, and oldest. It is also home to both the highest and lowest points in the 48 contiguous states. The state is generally divided into Northern and Southern California, although the boundary between the two is not well defined. San Francisco is decidedly a Northern California city and Los Angeles likewise a Southern California one, but areas in between do not often share their confidence in geographic identity. The US Geological Survey defines the geographic center of the state at a point near North Fork, California.

Southwestern United States Geographical region of the United States

The Southwestern United States, also known as the American Southwest or simply the Southwest, is a geographic and cultural region of the United States that generally includes Arizona, New Mexico, and adjacent portions of California, Colorado, Nevada, Oklahoma, Texas, and Utah. The largest cities by metropolitan area are Phoenix, Las Vegas, El Paso, Albuquerque, and Tucson. Prior to 1848, in the historical region of Santa Fe de Nuevo México as well as parts of Alta California and Coahuila y Tejas, settlement was almost non-existent outside of Nuevo México's Pueblos and Spanish or Mexican municipalities. Much of the area had been a part of New Spain and Mexico until the United States acquired the area through the Treaty of Guadalupe Hidalgo in 1848 and the smaller Gadsden Purchase in 1854.

Western United States One of the four census regions of the United States of America

The Western United States is the region comprising the westernmost states of the United States. As American settlement in the U.S. expanded westward, the meaning of the term the West changed. Before about 1800, the crest of the Appalachian Mountains was seen as the western frontier. The frontier moved westward and eventually the lands west of the Mississippi River were considered the West.

Great Basin Large depression in western North America

The Great Basin is the largest area of contiguous endorheic watersheds – those with no outlets – in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California, Mexico. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than 100 miles (160 km) away at the summit of Mount Whitney. The region spans several physiographic divisions, biomes, ecoregions, and deserts.

Sonoran Desert Desert in northwestern Mexico and the southwestern United States

The Sonoran Desert is a North American desert and ecoregion that covers large parts of the southwestern United States, as well as the northwestern Mexican states of Sonora, Baja California, and Baja California Sur. It is the hottest desert in both Mexico and the United States. It has an area of 260,000 square kilometers (100,000 sq mi).

Great Basin Desert Desert in the western United States

The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range. The desert is a geographical region that largely overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, and the Central Basin and Range ecoregion defined by the U.S. Environmental Protection Agency and United States Geological Survey. It is a temperate desert with hot, dry summers and snowy winters. The desert spans a large part of the state of Nevada and extends into western Utah, eastern California, and Idaho. The desert is one of the four biologically defined deserts in North America, in addition to the Mojave, Sonoran, and Chihuahuan Deserts.

Ecology of California

The ecology of California can be understood by dividing the state into a number of ecoregions, which contain distinct ecological communities of plants and animals in a contiguous region. The ecoregions of California can be grouped into four major groups: desert ecoregions, Mediterranean ecoregions, forested mountains, and coastal forests.

Oasisamerica Pre-Columbian cultural region of North America

Oasisamerica is a term that was coined by Paul Kirchhoff and published in a 1954 article, and is used by some scholars, primarily Mexican anthropologists, for the broad cultural area defining pre-Columbian southwestern North America. It extends from modern-day Utah down to southern Chihuahua, and from the coast on the Gulf of California eastward to the Río Bravo river valley. Its name comes from its position in relationship with the similar regions of Mesoamerica and mostly nomadic Aridoamerica. The term Greater Southwest is often used to describe this region by American anthropologists.

The Californias Region of the North America continent

The Californias, occasionally known as The Three Californias or Two Californias, are a region of North America spanning the United States and Mexico, consisting of the U.S. state of California and the Mexican states of Baja California and Baja California Sur. Historically, the term Californias was used to define the vast northwestern region of Spanish America, as the Province of the Californias, and later as a collective term for Alta California and the Baja California Peninsula.

Lower Colorado River Valley Landform in Arizona and California

The Lower Colorado River Valley (LCRV) is the river region of the lower Colorado River of the southwestern United States in North America that rises in the Rocky Mountains and has its outlet at the Colorado River Delta in the northern Gulf of California in northwestern Mexico, between the states of Baja California and Sonora. This north–south stretch of the Colorado River forms the border between the U.S. states of California/Arizona and Nevada/Arizona, and between the Mexican states of Baja California/Sonora.

Deserts of California

The Deserts of California have unique ecosystems and habitats, a sociocultural and historical "Old West" collection of legends, districts, and communities, and they also form a popular tourism region of dramatic natural features and recreational development. All of the deserts are located in eastern Southern California, in the Western United States.
