Considering the significance of this place let’s explore the Initial Point of Boundary Between U.S. and Mexico. It stands as the westernmost boundary marker between the United States and Mexico. Since its erection, this monument has marked the southwestern corner of the Continental United States.
In 1848, the Treaty of Guadalupe Hidalgo defined the initial border point. It was set one marine league south of the southernmost point of San Diego Bay. From there, the border proceeds in a straight line. It heads towards the confluence of the Colorado River and the Gila River.
The Initial Point of Boundary Between U.S. and Mexico holds immense historical weight. Its importance is etched on the west side of the original marble shaft. The inscription declares it as the “Initial point of Boundary between the United States and Mexico”. It states it was established by the Joint Commission on October 10, 1849. This was done agreeably to the Treaty of Guadalupe Hidalgo. The treaty was dated February 2, 1848. The inscription also credits John B. Weller, U.S. Commissioner and Andrew B. Gray, U.S. Surveyor.
Originally, in 1849, the boundary marker was a simple cairn of rocks. This followed the signing of the Treaty of Guadalupe Hidalgo. A more permanent marker was created later. A white marble shaft was manufactured in New York. It was transported around Cape Horn on the USS Supply to San Diego. In June 1851, it was erected and dedicated in Imperial Beach.
The marble monument was an obelisk. It stood approximately 20 feet tall resting on a marble pedestal. Atop the obelisk was an inverted acorn. This symbolized the strength of the California live oak tree.
By 1894, the monument had suffered greatly from visitors. Its outlines were nearly destroyed and the inscriptions partly obliterated. The Barlow-Blanco Commission renovated the monument in San Diego. It was reconstructed at the site. An enclosure was added to protect it. As of 1974, the reconstructed marble monument still stood at its original site.
In August 1971, Mrs. Pat Nixon turned over 372 acres of surplus Navy land. This land, formerly known as Border Field, became a beach park for the people of California. It was part of President Richard Nixon’s “Legacy of Parks”. The area is now known as Border Field State Park.
Before 1994, the US-Mexico border fence bisected the Initial Point of Boundary Between U.S. and Mexico. Operation Gatekeeper in 1994 restricted access to the marker from the United States side. Today, the border fence runs north of the marker. It is now possible to walk around the monument from Playas de Tijuana in Mexico. It remains a popular attraction.
The Initial Point of Boundary Between U.S. and Mexico stands as a testament to history. It marks not just a border but also the complex relationship between two nations. It has evolved. It has been rebuilt, and it has adapted to changing times. Yet, its significance as a marker remains.
