The Canada-US border, the longest land boundary in the world at 5,500 miles, is marked by a 20-foot wide cleared strip of forest called the 'slash,' maintained by the International Boundary Commission with approximately 8,000 monuments along the route, making it the most undefended border in the world despite being the longest.

The Surprising Truth About the Canada-US Border!Added:
Did you know that most of the Canada and United States border [music] is just a cleared strip of forest?
Yes, they decided to mark the longest land boundary in the world that way.
5,500 miles from Maine to Alaska by simply cutting a 20-ft wide strip of forest wherever there are trees. This deforestation is also known as the slash. The dividing line is also marked by monuments.
>> [music] >> There are about 8,000 of them along the border.
All this is done to physically mark the border.
>> [music] >> For example, during a hike, a person can easily identify the boundary.
>> [music] >> The slash is maintained by the International Boundary Commission, which removes new trees there every 5 to 15 years. An interesting fact, clearing these trees costs [music] each US taxpayer about 50 cents per year.
Unlike the southern border, there are no fences, barriers, or military support, making the USA-Canada border the most undefended in the world. However, >> [music] >> you can't easily cross the slash there.
Residents of the USA and Canada can only cross the border through checkpoints [music] located on major roads.
