As described by the National Geodetic Survey in 1973 (although already monumented by the CGS back in 1959):

"0.3 MI E FROM KATY.
ABOUT 0.3 MILE EAST ALONG THE MISSOURI-KANSAS-TEXAS RAILROAD FROM THE STATION AT KATY, ABOUT 5.2 FEET SOUTHWEST OF THE SOUTHEAST CORNER OF THE AMERICAN RICE GROWERS CO-OP ASSOCIATION OFFICE BUILDING, 167.6 FEET NORTH OF THE NORTH RAIL OF THE MAIN TRACK, 13.5 FEET EAST OF THE CENTER LINE OF THE ENTRANCE TO THE BUILDING, 3.6 FEET SOUTH OF THE SOUTH FACE OF THE BUILDING, AND IS A DISK SET ON THE TOP OF A 5/8-INCH COPPER COATED STEEL ROD AND PROTECTED BY A 6-INCH TILE WHICH PROJECTS 0.2 FOOT BELOW THE LEVEL OF THE GROUND. THE ROD WAS DRIVEN TO A DEPTH OF 40 FEET."

The 1973 NGS description provides a good general reference, but requires significant updates (as noted below) -- alternatively, one can use the gallery images for any future attempt at actual recovery. Updates include:
* The "American Rice Growers Co-Op Association" office building is still there (and therefore any NGS references such as "5.2 ft SW of the SE corner of the building, etc etc" is still valid), but the Co-Op no longer exists... The building is now an office for the "No Label" Brewing company.
* The disk is no longer protected by a 6" tile... It is now level with the ground, and may at times be completely covered over with lawn grass (as was the case when I recovered it).

Furthermore, the NGS recorded coordinates are a little off, at least at the time of this waymark's posting. Its associated NGS Data Sheet reports it as "N 29° 47 11 W 095° 48 55" (i.e. "N 29° 47.183 W 95° 48.917"), which points to a location ~90ft SSE of the actual BM, on the office's dirt road entryway. The actual coordinates -- as measured within 15' accuracy -- are "N 29° 47.191 W 095° 48.926".

Below are some additional facts, per the NGS database (with some editing for length): (visit link)
