Texline

Texline is a town in northwestern Dallam County, Texas, United States. The population was 507 at the 2010 Census. The town is named for its location near the New Mexico-Texas state line. The town sits on U.S Highway 87, which continues southeast towards Dalhart and northwest towards Clayton, New Mexico.

For years there has been a simmering dispute over whether Texline is lawfully a part of 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 2.29 and 3.77 miles too far west of that line. this survey error resulted in the current towns of Farwell, Texline, and a part of Glenrio being within the State of Texas. New Mexico's short border with Oklahoma, in contrast, was correctly surveyed on the 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 for all purposes are taxed and governed by the State of Texas.
