Bartlett Garcia Continental Survey Point

On April 24, 1851, John Russell Bartlett for the United States and Pedro Garcia-Conde for the Republic of Mexico, erected near here a monument designating 32022’ north latitude on the Rio Grande as the initial point for the official survey of the U.S. – Mexico boundary. After the Gadsden Purchase of 1853, the international boundary was moved south and the former Mexican lands were ceded to the U.S.
