[I]The following information, along with photos, was submitted to NGS, who subsequently declared this station Destroyed:[/I]
We found what we believe to be the three remaining (of four) anchor points for the legs of the airway beacon tower. No part of the northwest leg was found, but it was easy to determine its prior position by taking measurements from the other legs. This position coincided with the measurement of 17.7 feet west from station LY2803 (given in LY2803's description). WAAS-corrected coordinates obtained at what would have been the center of the base of the tower were identical to those coordinates given on the datasheet.

[B]Station landmark no longer exists.[/B]
This station was located and identified but the station landmark was destroyed. The airway beacon tower was dismantled and removed. Three of the embedded anchor points for the beacon tower legs remain protruding roughly 12-15 inches above the ground. The fourth leg, which is referred to in the historic description for LY2803, appears to have been close to the edge of the gravel roadway and was most likely pulled out. At what would have been the center of the base of the tower, a Garmin GPSmap76 receiver was used to record WAAS-corrected coordinates which were identical to the adjusted coordinates listed on the NGS datasheet. ~Rich in NEPA~
[I]Note: NGS has subsequently declared this station as destroyed based on a recovery report submitted by Zhanna.[/I]

Documented History (by the NGS)
|1/1/1942 by CGS (MONUMENTED)
|DESCRIBED BY COAST AND GEODETIC SURVEY 1942 (FBQ)
THIS INTERSECTION STATION IS LOCATED ABOUT 2 MILES E OF TUNKHANNOCK ON THE E END OF A HILL KNOWN AS LAND HILL. IT IS THE FIRST BEACON W OF THE SCRANTON MUNICIPAL AIRPORT ON THE BUFFALO-NEW YORK CITY AIR LINE. IT IS A STANDARD TYPE AIR-LINE BEACON AND IS MOUNTED ON A 50-FOOT TOWER. THE POINT LOCATED WAS THE CENTER OF THE REVOLVING WHITE LIGHT.
- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in January 1999.
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
