Texhomex is a marker showing the tri-point of Oklahoma, Texas and New Mexico. The marker is off U.S. Highway 56 about two miles east on Texas State Line Road at the corner of Oklahoma State Line Road, and is at an elevation of 4712 feet.[1] There are no signs on Highway 56 in either direction.
The tri-state marker is in a pasture and can be accessed by walking over a cattle guard.[2] [3] [4]
It is a concrete post a few feet tall with a metal circle at the top which describes the technical position of the post.
The Northwest corner of the Texas panhandle is located 2.2 miles west of this point, which was due to originally a surveying error in 1859. The joint congressional resolution in 1911 declared the line surveyed by Clark to be the actual boundary line between Texas and New Mexico. The Northwest corner of the Texas panhandle had been previously marked[5] but the marker was either removed or buried when the highway was widened in 2016.[6]
The marker for the Cimarron Meridian is located approximately 100 feet north of the Texhomex corner, and is marked by a concrete pillar and a sign.[7]
