In 1966, Congress established Chamizal National Memorial to commemorate the Chamizal Convention (treaty) of 1963. The Chamizal treaty finally ended a long-standing border dispute between the U.S. and Mexico. The 1848 Treaty of Guadalupe-Hidalgo established the Rio Grande/Río Bravo as the international boundary between the U.S. and Mexico. However, rivers naturally move over time. In this case, the river gradually, and at times abruptly, moved south, which left Mexico with less land than the 1848 treaty established. The land disputes that arose because of the river movement caused tension between the U.S. and Mexico for more than 100-years. Finally, in 1963 U.S. President John F. Kennedy and Mexican President Adolfo Lopez Mateos met to discuss the "Chamizal Issue" and through diplomatic negotiations, they solved the Chamizal Issue with the signing of the Chamizal Treaty.

En 1966, nuestro Congreso hizo El Trato de Chamizal. Termino el disputo entra los Estados Unidos y Mexico. El Trato de Guadalupe-Hidalgo establizo la frontera el Rio Grande / Rio Bravo. Despues, el rio movio con tiempo. En este caso, el rio cambio por el sur y Mexico quedo con menos tierra. El disputo y el movimiento del rio causo tension entra los Estados Unidos y Mexico sobre cien años. Al final, en 1963, El Presidente Johnson y El Presidente Lopez Mateos tuvieron junta y firmaron El Trato Chamizal.

Surveyor
In 1848, the Treaty of Guadalupe Hidalgo established the boundary between the United States and Mexico. Surveyors from both countries spent the next eight years mapping the over 2,000 mile political border. This sextant, used for measuring angles and determining latitude coordinates, is typical of the instruments used by surveyors and is on display in the Memorial’s historical exhibition.
