BL1573 - "F 1023" bench mark disk - Harris County, TX - U.S. Benchmarks on Waymarking.com

The marker was first monumented by the CGS back in 1954. As described by the NGS 19 years later, back in 1973:

"1 MI N FROM HOCKLEY.
ABOUT 1 MILE NORTH ALONG HEGAR RD. FROM THE JUNCTION OF US HIGHWAY 290 AND HEGAR RD., ABOUT 0.3 MILE NORTH OF A BRIDGE OVER A DRAINAGE DITCH, 49.8 FEET EAST OF AND ACROSS FROM THE ROAD FROM A POWER POLE, 25.8 FEET EAST OF THE CENTER LINE OF THE ROAD, 1.3 FEET WEST OF A FENCE, 1 FOOT NORTH OF A METAL WITNESS POST, ABOUT LEVEL WITH THE ROAD, AND SET IN THE TOP OF A CONCRETE POST PROJECTING 0.1 FOOT."

The 1973 description and associated reference points (i.e. distances/directions) are good references for locating this station, or at least what's left of it: the round concrete post has been dislodged from its setting and the actual BM disk is completely gone; all that remains is its the contour of where the metal disk used to be, along with its broken stem.

The BM is now marked as "destroyed" by the NGS, per my geocaching.com 08/31/2014 log entry. For reference, an NGS Datasheet search (on destroyed PID's) revealed the following information (summarized for brevity):
