As described by the NGS in 1974:
"[...] THE STATION MARK, STAMPED CG 11 1974, IS A STANDARD DISK SET IN A DRILL HOLE IN THE CONCRETE SEAWALL. IT IS 100 FEET WEST OF THE EAST END OF THE SEAWALL, 3 FEET SOUTH OF THE NORTH EDGE OF THE SEAWALL AND 1.8 FEET NORTH OF THE SOUTH EDGE OF THE SEAWALL. NOTE--THERE WERE NO REFERENCE MARKS SET FOR THIS STATION. NEAREST TOWN--PORT BOLIVAR."
The NGS description is still very accurate -- and so are the distance estimates. Likewise, the NGS' currently posted coordinates ("N 29 21 47.90213 W 094 45 30.41154") seemed quite accurate as well: my original measurements were "N 29 21.800 W 94 45.507", but another visit confirmed it was indeed "N 29 21.798 W 94 45.507".
The station was recovered in good condition.
