In 1803, with the authorization of the Louisiana

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.
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.

The three main types of land boundaries are natural boundaries, political boundaries, and cultural boundaries. Natural boundaries are formed by physical features such as rivers, mountains, or lakes; political boundaries are established by governments to define territorial limits; and cultural boundaries are based on cultural differences, such as language or religion. Each type serves to delineate areas for governance, resource management, and social identity.
Natural boundaries can include landforms like rivers, mountains, and oceans that divide territories or regions. These boundaries are formed by natural features of the Earth's landscape and can be used to separate countries, states, or other geographical areas.
