MT is the postal code abbreviation for the state of Montana. Nicknamed "the Treasure State" and "Big Sky Country," Montana is home to 1,005,141 people and has been a state since Nov. 8, 1889.
Among the 50 states, Montana is ranked fourth in size but 44th in population. Tourist attractions include Glacier National Park, the Little Bighorn Battlefield National Monument and Yellowstone National Park. Montana gets its name from the Spanish word "montaña," meaning "mountain."
The question, "What state is MT?" might also be interpreted as a humorous riddle since it sounds like, "What state is empty?'". No state is a perfect answer to the riddle since no state is literally empty, but Montana may be an appropriately humorous answer given its population-density rank of 48.
