Montana is generally divided into two main regions:
Eastern Montana and Western Montana. The Continental Divide of the [[Rocky Mountains (United States of America) | Rocky Mountains]] separate the smaller western portion from the larger eastern portion. Western Montana is characterized by higher rainfall in some areas, and terrain dominated by mountains, making for picturesque scenery such as that found in [[Glacier National Park]].

Some areas feature erosion-built features such as buttes and badlands.
