AJ1051 O 39 -- Laredo TX - U.S. Benchmarks on Waymarking.com

The old latitude and longitude station at Fort McIntosh was established most likely before the turn-of-the-20th century.

In 1917, the US COast and Geodetic survey passed through the local area setting modern benchmark disks. At that time, this old rough limestone post got a bronze benchmark disk affixed to its center.

This unique benchmark survived the decommsissioning of the fort, and can now be found on the campus of the Laredo Community College.
