If you want to get geographical you have to configure in the Red River of the North which flows north unlike the Mississippi and it cuts the drainage basin short up north in the Minnesota/North Dakota area. Here is a link to show you a picture: http://toxics.usgs.gov/hypoxia/images/mississippi_river_watershed.gif The Rocky Mountains are in the west. They act as a barrier. The appalcian mountains in the east probably do as well.

A natural boundary is formed with natural geographic features, such as mountain ranges and rivers. They often become political boundaries. However, political boundaries are boundaries between countries, and they do not really care about natural geographic features, like mountain ranges. They just draw out in the land by politicians.
Mountains, rivers, oceans, and deserts were natural features that served as boundaries between culture areas.

The Mississippi River marked the eastern boundary of the Louisiana Purchase, while the Rocky Mountains served as the western boundary.
Natural boundaries are physical features that define the borders of a region, such as rivers, mountains, oceans, and deserts. These boundaries are created by nature and can help to separate one area from another based on the geographical features present. Natural boundaries are often more permanent and easier to identify compared to artificial boundaries created by humans.
