Intermountain West
From Wikipedia, the free encyclopedia
The Intermountain West is a region of North America lying between the Rocky Mountains to the east and the Cascades and Sierra Nevada to the west. It is also called the Intermountain Region.
[edit] Topography
Many of the Intermountain Region's mountains' streams and rivers never reach the sea. Instead they flow into brackish lakes or into desert sinks. Only some rivers are able to reach the ocean. Some portions are made productive by irrigation systems. Cattle ranching is another process used.
[edit] Climate
The climate of the Intermountain Region is affected be location and elevation. The winters depend on location. In the southern parts, the winters are short, warm, and have little precipitation. In the northern portions, the winters are cold and moist, with hot and dry summers. This portion lacks precipitation as well, but the weather is moderate.
[edit] Vegetation
The vegetation ranges from sparse grassland to plants that are able to survive in desert conditions. Higher areas have thin, pine forests.
