The U.S. claim to NW Montana, the area between the Rockies and the N Idaho border, was validated in the Oregon Treaty of 1846 with the British.
Montana also contains a number of rivers, many of which are known for "blue-ribbon" trout fishing, but which also provide most of the water needed by residents of the state, as well as being a source of hydropower.
Montana was the scene of the Native Americans' last effort to keep their land, and the last stand of U.S. Army Lieutenant Colonel George Armstrong Custer was fought near the present day town of Hardin.
The cow camp job was, and is, still the most desired job of a cowboy, but only the most senior and lucky ones get to do it.
