As described by the CGS back in 1935:

"IN GIDDINGS.
AT GIDDINGS, LEE COUNTY, AT THE NORTH ENTRANCE TO THE COUNTY COURTHOUSE, AND ON THE TOP OF THE WEST END OF THE THIRD STEP. AN OUTLINED CHISELED SQUARE."

The 1935 description and associated reference points (i.e. directions / number of "steps") are still good references for locating this station, however one clarification might be in order:
* There are actually TWO "north" entrances to the courthouse ("northeast" and "northwest"), and as such the "NORTH ENTRANCE" reference may be a little misleading. The station in question is at the NORTHWEST entrance, 3rd step of the granite staircase, western end of the 5ft-wide step.

The station's associated NGS Data Sheet's posted coordinates are pretty much in line with my own observations: the NGS reports the station at "N 30 10 53.4 W 096 56 13.8" which was quite close to my own readings -- as measured within 15' accuracy and 20+ reading averages: "N 30° 10.891 W 96° 56.232".

The station was recovered in "decent" condition: the chiseled square's etching is probably not as pronounced as is was when originally created, but still visible if one knows what to look for. See posted waymark's gallery images for BM close-up and setting details; some additional pictures are available on the NGS website as well.
