The terrain of the Mountain West is more diverse than any other region in the United States. Its physical geography ranges from some of the highest mountain peaks in the continental United States, to large desert lands, and rolling plains in the eastern portion of the region. The Mountain West states contain all of the major deserts found in North America. The [[Great Basin Desert]] is located in almost all of Nevada, western Utah, and southern Idaho. Wyoming also has a vast amount of desert land in the southwestern portion of the state, which is known as the [[Red Desert (Wyoming)|Red Desert]]. Portions of the [[Mojave Desert]] are located in California, but over half of the desert is located in southern Nevada, in the Mountain West. Meanwhile, the [[Sonoran Desert]] is located in much of Arizona, and the [[Chihuahuan Desert]] is located in most of southwestern and southern New Mexico. Colorado also has scattered desert lands in the southern and northwestern portions of the state including the expansive [[San Luis Valley]].

Colorado, New Mexico, Utah, and Arizona have other smaller desert lands, part of the [[Colorado Plateau]]. The [[Painted Desert, Arizona|Painted Desert]] is located in northern and northeastern Arizona, and the [[San Rafael Desert]] is located in eastern Utah. New Mexico has other desert lands located in the northern and northwest. Colorado has large desert lands on the Colorado plateau in the northwestern, western, and southern parts of the state. These desert lands in Colorado are located in and around areas such as [[Royal Gorge]], [[Great Sand Dunes National Park]], [[Pueblo, Colorado|Pueblo]], the [[San Luis Valley]], [[Cortez, Colorado|Cortez]], [[Dove Creek, Colorado|Dove Creek]], [[Delta, Colorado|Delta]], [[Canyons of the Ancients National Monument]], the [[Roan Plateau]], [[Dinosaur National Monument]], [[Colorado National Monument]], and the [[Grand Mesa]].<ref>[http://research.allacademic.com/meta/p_mla_apa_research_citation/2/6/6/3/3/p266339_index.html The Shifting Terrain of the Mountain West].

In the far eastern portions of the Mountain West are the High Plains, a portion of the [[Great Plains]].

The High Plains receive very little rainfall and sit at high elevations, usually about {{convert|3000|to|6000|ft}}.

Regional definitions vary from source to source. The states shown in dark red are always included, while the striped states are usually considered part of the same region called the Mountain States.
An enlargeable map of the Rocky Mountains of western North America.

The Mountain States (also known as the Mountain West and the Interior West) form one of the nine geographic divisions of the United States that are officially recognized by the United States Census Bureau. It is a subregion of the Western United States. The Mountain States are usually split up into two other regions known as the Northwest and Southwest. Idaho, Montana, and Wyoming are considered part of the Northwest, while Arizona, New Mexico, Colorado, Nevada, and Utah are considered part of the Southwest.

The division consists of eight states: Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming. These eight states have the highest mean elevations of all 50 U.S. states. Together with the Pacific States of Alaska, California, Hawaii, Oregon and Washington, the Mountain States constitute the broader region of the West, one of the four regions the United States Census Bureau formally recognizes (the Northeast, South, and Midwest being the other three). The word "Mountain" refers to the Rocky Mountains, which run north-south through portions of the states of Montana, Idaho, Wyoming, Colorado, Utah, and New Mexico. Arizona and Nevada, as well as other parts of Utah and New Mexico, have other smaller mountain ranges and scattered mountains located in them as well.

Mountain Time is observed in nearly the entire division, except Nevada (all but the stateline city of West Wendover) and the Idaho Panhandle. Daylight saving time is not observed in Arizona, except for lands within the Navajo Nation (northeast corner of the state) which observe daylight saving time due to the Nation traversing state lines. For this reason, most of Arizona is one hour behind the rest of the Mountain Time Zone from the second Sunday in March until the first Sunday in November.[1]

Phoenix is the largest city and metropolitan area of the Mountain States, followed by Denver, Las Vegas, and Salt Lake City.

Regional geography

The Grand Canyon of the Yellowstone in Wyoming

The Mountain West is one of the largest and most diverse regions in the United States. Most regional boundaries of the Mountain West are often looked at as the area from the High Plains to the Sierra Nevada and Cascade Range. The southern and northern portions of the Mountain West are often split into two separate regions. The southern portion (Arizona, New Mexico, Utah, Colorado, and Nevada) is often called the greater Southwest region, while the northern portion (Wyoming, Idaho, and Montana) is often called either the Northwest states or the Northern Mountain West region.[2]

Climate

Snow on the Great Basin Desert of Nevada
The Painted Desert in northeastern Arizona

The climate of the Mountain West is one of the more diverse climates in the United States. The entire region generally features a semi-arid to arid climate, with some alpine climates in the mountains of each state. Some parts of the tall mountains can receive very large amounts of snow and rain, while other parts of the region receive very little rain and virtually no snow at all. The High Plains in the eastern portion of the region receive moderate snowfalls, but virtually very little rain at all.

The states of Nevada and Arizona are generally filled with desert lands and scattered mountain ranges. Much of Nevada receives little to no snow in the southern portion of the state, while northern Nevada can receive large amounts of snow in and around the mountains, and even in the desert lands in Nevada. Arizona generally receives little rain or snow, but high elevations in and near mountains receive extremely large amounts of rain and snow. Northern and northeastern Arizona display characteristics of a "High Desert", where the summers are very hot and dry, while the winters can become very cold and it can snow as well.

Utah is also generally large desert lands with mountains as well. However, the desert lands in Utah receive significant snowfalls, and there are large snowfalls in and around the mountains. Colorado and New Mexico have very similar climates. Both states can receive significant snowfalls off the mountains, while the mountains in both states receive extremely large amounts of snow. However, southern and southwestern New Mexico generally does not receive much snow at all, similar to southern Nevada and southern Arizona. The desert lands found in northeastern Arizona, eastern Utah, northern New Mexico, and western and southern Colorado are generally referred to as the "High Desert" lands.

The northern portion of the Mountain West tends to be a bit cooler than the southwestern areas. Wyoming, Idaho, and Montana all receive significant snowfalls off the mountains and very large snowfalls in the mountains. The High Desert also exists in the northern Mountain West. Southeastern Oregon, southern Idaho, and southwestern Wyoming have the Great Basin Desert lands located in them, which is part of the high desert.[3]
