Most people in this area know about the "Ark-La-Tex", but some do not know where the states of Arkansas, Louisiana and Texas geographically meet. There is a concrete monument about 11 miles southeast of Atlanta Texas on Texas Highway 77 that marks the exact location. It is also the termination point of Louisiana Highway 1, northwest of Zylks and Rodessa, Louisiana, and about 43 miles from Shreveport. The community of Ravanna, Arkansas lies directly to the north.
This U.S. Coast & Geodetic Survery Triangulation Station identifies the meeting of the states of Arkansas, Louisiana and Texas. The station also marks the location where Lafayette County Arkansas, Cass County Texas and Caddo Parish Louisiana meet. Most survey marks across the country were set by the U.S. Coast & Geodetic Survey, now called the National Geodetic Survey (NGS).
Benchmarks (survey marks, survey monuments, or geodetic marks) are objects placed to indicate key survey points along the Earth's surface. They are used primarily in geodetic and land surveying. Informally, such marks are referred to as benchmarks, although strictly speaking the term "benchmark" is used to indicate elevation. Benchmarks typically consist of bronze plates set in stone or concrete. Some are marked with the elevation to the nearest foot above mean sea level, however most are not marked with any indication of elevation.
This marker is at Latitude 33 01 09.19955(N) Longitude 094 02 35.21446(W), and labeled as NGS DM1223. The monument was placed by the Coast & Geodetic Survey in 1930. The site is located in USGS Ravanna Quad.

The concrete monument resides at the base of an ever-encroaching tree. A colorful sign marking the site was erected in 2023 by local residents and sponsored by the nearby Magnolia Club House in Louisiana. See photos below.
