There are fifty-six counties in 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.
