The farthest boundary between settled and unsettled territory is often referred to as the "frontier." This boundary represents the edge of human civilization, where agricultural practices and urban development give way to wilderness and uninhabited land. Throughout history, frontiers have shifted due to exploration, colonization, and population movement, reflecting changes in societal expansion and resource availability. The concept varies by region and context, influenced by factors such as geography, culture, and technology.
The natural boundary between British Columbia and Alberta is primarily formed by the Rocky Mountains. This mountain range serves as a significant geographical divide, influencing the flow of rivers and the climate in the respective provinces. Additionally, the Continental Divide runs along parts of this boundary, marking the separation between watersheds that drain into the Pacific Ocean and those that drain into the Arctic and Atlantic Oceans.
The disputed territory is often marked by natural geographic boundaries such as rivers, mountains, or lakes. For example, the Himalayas serve as a boundary in the conflict between India and Pakistan over Kashmir, while the Rio Grande acts as a border between the United States and Mexico. These natural features can complicate territorial claims and influence historical and political tensions in the region.

The new border between British and Spanish territory in North America was established by the Treaty of Paris in 1763, following the conclusion of the French and Indian War. The treaty ceded Florida to Britain and recognized the Mississippi River as the boundary between British territories to the east and Spanish territories to the west. This division effectively marked the expansion of British influence in North America while placing Spanish holdings primarily in the region west of the Mississippi.
The two rivers that marked the northern boundary between Spanish territory and the United States in 1819 were the Sabine River and the Red River. This boundary was established through the Adams-Onís Treaty, which defined the limits of Spanish territory in North America. The treaty aimed to settle disputes and clarify territorial claims between the U.S. and Spain.

The Oregon Treaty set the boundary at the 49th Parallel.
In order to resolve the Aroostook War, Daniel Webster and the British ambassador, Lord Alexander Ashburton, had to create a treaty. In this treaty, known as the Webster-Ashburton Treaty, the territory that was fought over was split between Maine and British Canada. The treaty also settled the boundary of the Minnesota territory.
Baffin Bay forms a natural boundary between Greenland (an autonomous territory of Denmark) and Baffin Island (part of the Canadian territory of Nunavut).
The United States made a treaty with Britain to acquire the Oregon Territory through the Oregon Treaty of 1846. This agreement established the boundary between U.S. and British territories at the 49th parallel, except for the area around Vancouver Island, which remained under British control. The acquisition of the Oregon Territory was significant in expanding U.S. territory westward and fulfilling the concept of Manifest Destiny.
