For years, a simmering dispute had existed over of which state the east part of Glenrio is lawfully a part: Texas or New Mexico? The straight north-south border between the two states was originally defined as the 103rd meridian, but the 1859 survey that was supposed to mark that boundary mistakenly set the border between too far west of that line, making the current towns of Farwell, Texline, and the east part of Glenrio appear to be within Texas. New Mexico's short border with Oklahoma, in contrast, was surveyed on the correct meridian. New Mexico's draft constitution in 1910 stated that the border is on the 103rd meridian as intended. The disputed strip, hundreds of miles long, includes parts of valuable oilfields of the Permian Basin. A bill was passed in the New Mexico Senate to fund and file a lawsuit in the U.S. Supreme Court to recover the strip from Texas, but the bill did not become law. Today, land in the strip is included in Texas land surveys and the land and towns (the east part of Glenrio) for all purposes are taxed and governed by the State of Texas.
