As described by the NGS in 1987:
"THE STATION IS A PUNCH MARK IN THE TOP OF A STAINLESS STEEL ROD DRIVEN INTO THE GROUND AND INSIDE A 1-INCH PVC PIPE THAT IS 20 FEET LONG FILLED WITH GREASE THAT IS ENCASED IN A 5-INCH PVC PIPE WITH A LOGO CAP STAMPED---HGCSD 7 1986---, THE ROD IS RECESSED 7 CM BELOW THE GROUND. LOCATED 16.3 METERS (53.6 FT) WEST-SOUTHWEST FROM A FIRE HYDRANT, 13.6 METERS (44.5 FT) SOUTH FROM THE CENTERLINE OF THE EASTBOUND LANE OF [FM 1960], 9.3 METERS (30.5 FT) NORTH FROM THE NORTH CURB OF THE PARKING LOT AND 4.5 METERS (14.8 FT) EAST FROM THE EAST CURB OF THE ENTRANCE TO THE SHOPPING PLAZA."
An amendment by the NOS in 1992 is even more helpful:
"0.53 M (1.74 FT) SOUTHEAST OF THE NORTHEAST CORNER OF THE CONCRETE FOUNDATION FOR A SIGN, 0.27 M (0.89 FT) EAST OF THE EAST FACE OF THE FOUNDATION
The NGS and NOS descriptions are quite accurate (save for the fact that its stamping was "HGCSD 7 1987", not "HGCSD 7 1986"): the station is located about 300 feet west of the SW corner of FM-1960 and Timber Forest Drive, inside a flower bed and just a few feet east of a small sign/marquee within the "Lake Country Plaza" shopping strip parking area.
The NGS' currently posted coordinates ("N 29 59 55.11593 W 095 11 39.46068", or "N29° 59.919 W95° 11.658") were exactly in line with my observations, as measured within 10' accuracy and 10+ reading averages.
The station was recovered in decent condition, although its logo cap is missing.
