Found this one right where it was supposed to be.

Found while geocaching today.

The aluminum cap that was found is just as stated. It is only a survey control monument set for Washington city. It is not a replacement for the missing beacon. I know this because I was a member of the survey field crew that monumented this spot, and performed the survey control to establish its position. I could give you centimeter level coordinates on this point. By the way, there are a dozen or so like monuments ringing Washington on various high vantage points.

I went for a little bike ride to find this airway beacon. My goal was to figure out what an airway beacon should look like. I was expecting to see a tower as I road up the hill, so I was surprised to see that the old tower had been cut down. The given coordinates led me to the center of the remaining four tower legs. About 20 feet northwest, there is a new survey disk labeled WASHINGTON CITY SURVEY CONTROL - BEACON - 1994.

According to my GPS, the approximate coordinates of the new benchmark are N 37 02.705 W 113 31.117 (WGS84) at an elevation of 3065 feet. This puts the new benchmark approximately 20 feet northwest of the given coordinates.

Documented History (by the NGS)

01/01/1953 by CGS (FIRST OBSERVED)
DESCRIBED BY COAST AND GEODETIC SURVEY 1953 (LGT) THE STATION IS ABOUT 6 MILES SOUTHEAST OF ST. GEORGE, 6 MILES SOUTH OF WASHINGTON AND 1/2 MILE NORTHWEST OF THE ST. GEORGE CIVIL AERONAUTICS AUTHORITY AIRPORT. IT IS ON THE HIGHEST POINT OF A LOW, NORTHEAST-SOUTHWEST RIM. THE STATION IS THE CENTER OF THE REVOLVING, GREEN AND WHITE LIGHT OF BEACON 36 AT THE ST. GEORGE C.A.A. AIRPORT. THE BEACON TOWER IS PAINTED IN RED AND SILVER SECTIONS AND IS APPROXIMATELY 57 FEET IN HEIGHT. TO REACH THE STATION FROM THE C.A.A. BUILDINGS AT THE AIRPORT GO NORTHWEST ON THE ROAD TO ST. GEORGE FOR 0.3 MILE TO TWO ROAD FORKS ON THE LEFT. TURN LEFT, TAKE THE RIGHT ONE OF THE TWO FORKS, AND CONTINUE WESTERLY FOR 0.15 MILE TO THE END OF THE ROAD, ABOUT 300 FEET EAST OF THE BEACON.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in November 1997.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
