Alaska borders the Canadian province of British Columbia. This border stretches for about 1,538 miles (2,475 kilometers) along the southeastern part of Alaska. The boundary between Alaska and British Columbia is defined by the Alaska-British Columbia border, which runs through mountainous terrain and dense forests.
The border was established through a series of treaties and agreements between the United States and the United Kingdom (which was responsible for Canada’s foreign affairs at the time). The most significant of these agreements is the Alaska Boundary Treaty of 1903, which resolved a long-standing dispute over the exact location of the border.
This border is not only a geographical boundary but also a significant point of interest for travelers, as it connects the United States and Canada through various land routes, including the famous Alaska Highway.
