The significance of the monument is stated in the inscription on the west side of the original marble shaft: "Initial point of Boundary between the United States and Mexico, established by the Joint Commission, 10 October, A.D. 1849, Agreeably to the Treaty dated at the City of Guadalupe, Hidalgo, February 2, A.D. 1848.

The Tijuana River (Spanish: Río Tijuana) is an intermittent river, 120 mi (195 km) long, near the Pacific coast of northern Baja California state in northwestern Mexico and Southern California in the western United States.

Goat Canyon (Spanish: Cañón de los Laureles) also known as Cañón de los Laureles, begins in Tijuana, Mexico, and ends in the United States just north of the Mexico–U.S. border. The canyon is formed by Goat Canyon Creek, which receives water and other runoff from areas south of the border. Most of the canyon and its watershed lies within Baja California.The canyon originated during the Quaternary period; it is bordered by Bunker Hill to its west and Spooner's Mesa to its east. Part of the canyon contains coastal salt marshland and supports numerous sensitive and endangered species.Human activity in and around the canyon pre-dates European colonization; it was part of a route used by the Portolá expedition to San Diego Bay and later formed part of the Missionary Road, which was abandoned in the late 19th century. Farms existed in and around Goat Canyon until the area came under the control of the federal government of the United States. Development south of the Tijuana-Ensenada scenic highway began in the late 20th century, causing sewage to flow northward, a problem that persisted into the 21st century.
