Canada–United States international border vista
The Canada–United States international border vista is a man-made track of deforestation that demarcates portions of the border between the two nations.
Description
This border vista is a man-made cut-through of forestland maintained along areas of the border with dense forestation. There are many different sections of the vista, and the total length can vary depending on cycles of maintenance and upkeep, but an approximate length of has been reported by the United [States Department of Homeland Security].From a bird's eye perspective, the vista appears as a "line" running through the wilderness, and can be clearly seen on satellite imagery.

From the ground, one would observe that the vista follows a series of man-made survey monuments that mark the border along the northern 49th parallel, the Alaska/Canada border, and the non-linear eastern border. Because of inaccurate measurements by the official surveyors in the 19th century, the border and thus the vista strays from the intended location by hundreds of feet in some places. It is the actual location of the monuments, however, and not their intended location that defines the border by treaty. It is illegal to cross the vista without official permission.
