As described by the NGS in 1963:

"2.85 MI N FROM CEDAR BAYOU. ABOUT 2.6 MILES NORTH ALONG THE CROSBY-CEDAR BAYOU ROAD FROM THE ASSEMBLY OF GOD CHURCH AT CEDAR BAYOU, THENCE 0.25 MILE SOUTHWEST ALONG ARCHER ROAD, ABOUT 128 YARDS SOUTH OF THE CENTER LINE OF THE ROAD, ABOUT 0.1 MILE NORTHWEST OF A SMALL GROVE OF TREES, 37 FEET EAST OF THE CENTER LINE OF BARKALOW ROAD, 85 FEET SOUTH OF THE SOUTHWEST CORNER OF A METAL HANGAR AT THE HUMPHREYS AIRPORTS, 51 1/2 FEET SOUTHWEST OF THE SOUTHWEST CORNER OF A METAL HANGER, 50 FEET NORTH OF THE CENTER LINE OF A DIRT DRIVEWAY, 3 FEET EAST OF A FENCE, 1.6 FEET SOUTH OF A METAL WITNESS POST, AND SET IN THE TOP OF A CONCRETE POST PROJECTING 6 INCHES."

The NGS description probably needs to be revised a bit. It is indeed "0.25 MILE SOUTHWEST ALONG ARCHER ROAD, ABOUT 128 YARDS SOUTH OF THE CENTER LINE OF THE ROAD" and "37 FEET EAST OF THE CENTER LINE OF BARKALOW ROAD", but all other distances can probably be removed. Likewise, references to hangars and a fence are no longer valid. It is "SET IN THE TOP OF A CONCRETE POST", but it no longer project 6 inches (and is actually a bit buried over time). last but definitely not least, the witness post is still there... so recovery relatively easy: you will have to do a little bit of digging to clear off some dirt, though.

The NGS' currently posted coordinates ("N 29 47 23.0 W 094 57 29.9", or "N 29° 47.383 W 94° 57.498") were spot on: my measurements were N 29° 47.383 W 94° 57.499, i.e. they were just 4' off based on 10+ readings within 10' accuracy.

The station was recovered in good condition.
