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.

What that marker records spans 1777 to 1789, overlapping William Gabby's years there.

Marker data: Official Scenic Historic Markers program, New Mexico Historic Preservation Division, Department of Cultural AffairsMarker texts come from the Division’s published marker spreadsheet, reproduced with the Division’s written permission. Where that spreadsheet records a coordinate, the pin is the Division’s own; where it records only a highway and mile marker, an address, a junction or a named place, or where its coordinate contradicts its own highway, mile and county, the pin is ours, resolved on public road and place data and marked approximate.
