Texhomex
Texhomex is a marker showing the tripoint of Oklahoma, Texas, and New Mexico. The marker is off U.S. Highway 56 about 2 miles east on Texas State Line Road at the corner of Oklahoma State Line Road, and is at an elevation of 4712 feet. No signs are posted on Highway 56 in either direction.
The tristate marker is typically covered by soil, but a nearby concrete pillar marker can be seen across the fence a few feet away. A witness post and sign are a few inches from the underground marker.
