Glenrio, formerly Rock Island, is an unincorporated community in both Deaf Smith County, Texas, and Quay County, New Mexico, in the United States. Located on the former U.S. Route 66, the ghost town sits on the Texas–New Mexico state line. It includes the Glenrio Historic District which was listed on the National Register of Historic Places in 2007


The community was founded in 1903 as a railroad siding on the Rock Island Railroad. Its name is derived from Scots “glen” + Spanish “rio” (meaning “river”). Originally a railroad town, the village was renamed from Rock Island to Glenrio by the Rock Island and Pacific Railroad in 1908 and began receiving motorists on the dusty Ozark Trail in 1917. Its original structures were adobe buildings. The circa-1910 Angel House was in New Mexico.





Current Status:

On June 25, 2008, the State of New Mexico opened the Glenrio Welcome Center on Interstate 40 at the Texas state line. The center includes such things as a pet walk, a livestock corral, wireless Internet access, a movie theater, and information kiosks. Built to accommodate one million visitors per year, it includes green features such as recycling of greywater for grounds irrigation, and a wind turbine that will generate 20 percent of the center’s energy.


The location of Glenrio on Texas and New Mexico’s border led to some interesting business practices. At one point, all fuel was dispensed in Texas due to New Mexico’s higher gasoline taxes. The 1930s State Line Bar and motel were built in New Mexico because Deaf Smith County, Texas, was dry at the time. The railroad station was in Texas. The local post office, built circa-1935, was in New Mexico. A water tank and windmill in New Mexico were constructed circa 1945.
