The Mountain states have big peaks. 

The Mountain states are in the West. 
This area has many big mountains. The Rocky Mountains run through it. Some peaks are very high.
The land is very different. Some parts are hot deserts. Other parts have lots of snow.
Many people live here now. Phoenix is the largest city. 
It is a very big and busy place.
The Mountain states are in the Western United States. 
This region includes eight states. These are Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming. The Rocky Mountains run through many of these states. The highest peak is Mount Elbert. It is in Colorado.
The land here is very diverse. You can find high mountain peaks and large deserts. The Great Basin Desert covers much of Nevada.
The weather changes a lot. Some parts are very dry and hot. Other parts get a lot of snow. High mountains can be very cold and wet.
Many people live in this region. It is growing very fast. Phoenix is the largest city. 
The Mountain states are a special part of the Western United States. 

The land here changes very quickly as you travel. You might see some of the highest mountain peaks in the United States. You might also see large, dry desert lands. The Great Basin Desert covers almost all of Nevada and parts of Utah and Idaho.
The weather in the Mountain West is very varied. Many parts of the region are quite dry or even arid. However, the tall mountains can have their own special weather. Some mountains get huge amounts of rain and snow. Other parts of the region get very little rain. 
History and geography help us understand these states. The eight states together have the highest average elevation in the U.S. This means the land is mostly high up. Colorado has the highest peak called Mount Elbert.
Many people are moving to this region today. It is the fastest-growing part of the United States. Some of the fastest-growing states are Utah, Idaho, Nevada, Colorado, and Arizona. Phoenix is the largest city in the whole region. 


The Mountain states represent one of the nine official geographic divisions of the United States. 
Geographers often divide the Mountain West into several smaller subregions. The Southwest region includes Arizona, New Mexico, southern Nevada, and far west Texas. The Intermountain region consists of Utah, Nevada, and Idaho. There is also the Front Range region, which covers northern New Mexico, Colorado, and southeast Wyoming. Some people view the northern parts, like Idaho and Montana, as part of the Northwest or the Northern Rockies. The southern portion, including Arizona and New Mexico, is often separated as the Southwest. These different areas help describe the vast variety of land found here.
The terrain of the Mountain West is more diverse than any other U.S. region. It contains some of the highest mountain peaks in the continental United States. It also features massive desert lands and rolling plains in the east. The Great Basin Desert covers almost all of Nevada and parts of western Utah and southern Idaho.
Climate patterns in this region are also incredibly varied. Most of the area has a semi-arid or arid climate, meaning it is generally dry. However, alpine climates exist in the high mountains of every state. These mountain peaks can receive massive amounts of rain and snow. In contrast, other parts of the region receive very little moisture. The High Plains in the east receive moderate snow but very little rain. 
Elevation plays a massive role in the identity of these states. The eight Mountain states have the highest mean elevation of all 50 U.S. states. This means the average height of the land is higher here than anywhere else in the country. Colorado has the highest mean elevation of all the states.
Human populations in the Mountain West are changing rapidly. This is currently the fastest-growing region in the United States. States like Utah, Idaho, Nevada, Colorado, and Arizona are among the fastest-growing in the nation. Phoenix, Arizona, is the largest city in the region. 


The geography of the Mountain West connects many different natural systems. The region stretches from the High Plains to the Sierra Nevada and the Cascade Range. The landscape transitions from flat, rolling plains into rugged mountains and deep deserts. This variety of landforms creates many different habitats for plants and animals. Whether it is the canyon floors or the snowy mountain tops, the region is defined by its extreme changes in height and moisture.
