Canada–United States international border vista

[1] From a bird's eye perspective, the vista appears as a "line" running through the wilderness, and can be clearly seen on satellite imagery.

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.

[5] In more populous, less forested areas, this was accomplished largely with signs, monuments, physical barriers, and service roads; but the mountainous terrain and wilderness conditions in certain areas made that approach impractical, thus the 20-foot-wide track of deforestation was adopted as a solution.

The IBC reports a $1.4 million annual budget (total amount for all border maintenance, including vista clearing).

This can be challenging in the remote areas of the vista, so DHS and the CBP's divisions of border patrol cooperated to install third-party technology in the form of solar-powered, motion-detecting surveillance equipment, known as the Slash CameraPole system.
