Montana

Montana is a state in the Western United States. The western one-third of the state has numerous mountain ranges (approximately 77 named) of the northern Rocky Mountains; thus the state's name, derived from the Spanish word montaña 'mountain.' The state nickname is the "Treasure State." Other nicknames include "Land of Shining Mountains", "Big Sky Country", and the slogan "the last best place". The state ranks fourth in area, but 44th in population, and therefore has the third lowest population density in the United States. The economy is primarily based on agriculture and significant lumber and mineral extraction.[citation needed] Tourism is also important to the economy, with millions of visitors a year to Glacier National Park, the Battle of Little Bighorn site, and three of the five entrances to Yellowstone National Park.
