Montana is a state in the Western United States. The western third of the state contains numerous mountain ranges; other 'island' ranges are found in the central third of the state, for a total of 77 named ranges of the Rocky Mountains.
This is a list of the 56 counties in the US
state of Montana. Montana has two consolidated city-counties- Anaconda with Deer Lodge County and Butte with Silver Bow County. The portion of
Yellowstone National Park that lies within Montana was not part of any county until 1997, when part of it was nominally added to Gallatin County, and
the rest of it to Park County. Eight counties of the state are composed of two or more words.
