Montana
Montana is located in the western region of the United States. The western third of the state consists of 100 or more mountain ranges making up the Rocky Mountains. The boundary with Idaho is marked by the crest of the Bitterroot Range. The North American Continental Divide also runs along it. Eastern Montana forms part of the Great Plains. It is drained by the Missouri River and its tributaries, including the Yellowstone, Sun and Milk. The Plains consist of rolling prairies and badlands—rocky uplands where the soils have been stripped away by wind and water.
Name
The state's name come from the Spanish word montaña, meaning “mountain” or "mountainous country". The early Spanish explorers gave the name Montaña del Norte to the entire mountainous region of the American West on their travels across what is now the southwestern United States in the 16th century.
Climate
Eastern Montana has a semi-arid climate. The Rocky Mountains block the flow of warm, moist air moving east from the Pacific, and so have a significant effect on the climate in areas east of the mountains. Western Montana’s valleys have milder winters and cooler summers than the eastern plains. The mountain ranges themselves may receive several tens of feet of snow during winter months.
Economy
Fields of grain, mainly wheat and barley, but also some oats and rye, cover much of Montana's eastern plains. Flax, sugar beet, hay and potatoes are other important crops. Sheep and cattle ranches are also widespread on the pastures of the Great Plains, where once vast herds of bison roamed.
In Montana's mountainous west are the large mineral deposits which formed the basis of the state’s early economy: copper, silver, gold, platinum, zinc, lead and manganese. Coal, oil and natural gas reserves are located in the east. Leading manufactures are forest products, processed foods and refined oil.
Tourism is also an important industry. Every year, millions of tourists visit Glacier National Park, the Little Bighorn Battlefield National Monument and Yellowstone National Park, which lies partly within the state’s borders.
