DESCRIBED BY COAST AND GEODETIC SURVEY 1960 (JCC) STATION IS LOCATED ON THE NORTH RIGHT-OF-WAY OF OLD HIGHWAY 611, 0.2 MILE SOUTH OF THE WAYNE AND MONROE COUNTY LINE, 2-1/2 MILES WEST-SOUTHWEST OF GOULDSBORO, 5-1/2 MILES NORTHWEST OF TOBYHANNA AND 5.0 MILES SOUTH OF DALEVILLE. STATION IS REACHED AS FOLLOWS, FROM THE RAILROAD STATION IN GOULDSBORO GO WEST ON STATE HIGHWAY 507 FOR 2.5 MILES TO THE JUNCTION OF U.S. HIGHWAY 611. TURN LEFT, U.S. HIGHWAY 611 AND GO 0.1 MILE TO A GRAVELED ROAD ON THE LEFT. TURN LEFT, ON GRAVELED ROAD, AND GO ABOUT 150 FEET TO OLD CONCRETE HIGHWAY. TURN RIGHT AND GO 0.1 MILE TO STATION ON THE LEFT. STATION, STAMPED WANNA 1960, IS A STANDARD USC AND GS BRONZE DISK SET IN THE TOP OF A 10-INCH SQUARE CONCRETE MONUMENT THAT PROJECTS ABOUT 1 INCH ABOVE THE GROUND. IT IS 21.0 FEET NORTHEAST OF THE CENTER LINE OF OLD HIGHWAY 611, 21.0 FEET SOUTHWEST OF AN 18-INCH IN DIAMETER TRIANGULAR BLAZED MAPLE TREE, 2.0 FEET SOUTH SOUTHWEST OF A STANDARD METAL WITNESS POST AND MARKER. R.M. NO 1, STAMPED WANNA NO 1 1960, IS A STANDARD USC AND GS BRONZE DISK CEMENTED IN A DRILL HOLE IN A BOULDER THAT IS 3 X 5 FEET AND PROJECTS ABOUT 1 FT. ABOVE THE GROUND. IT IS 76.0 FEET SOUTH SOUTHWEST OF AN 18-INCH IN DIAMETER TRIANGULAR BLAZED MAPLE TREE, 61.4 FEET SOUTH SOUTHWEST OF A STANDARD METAL WITNESS POST AND MARKER, 26.0 FEET SOUTHWEST OF THF THE CENTER LINE OF OLD HIGHWAY AND ABOUT THE SAME ELEVATION AS THE STATION.

NORTHEAST OF A STANDARD METAL WITNESS POST AND MARKER AND ABOUT THE SAME ELEVATION AS THE STATION. TO REACH THE AZIMUTH MARK FROM THE STATION GO SOUTHEAST ON OLD HIGHWAY 0.1 MILE TO GRAVELED ROAD ON THE RIGHT. TURN RIGHT AND THEN LEFT ON U.S. 611 AND GO 0.28 MILE TO THE AZIMUTH MARK ON THE RIGHT.

RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1961 2.7 MI S FROM GOULDSBORO. 2.5 MILE WEST ALONG STATE HWY 507 FROM THE RAILROAD STATION IN GOULDSBORO TO THE JUNCTION OF STATE 507 AND U.S. HWY 611 THENCE SOUTH WEST 0.1 MILE ON U.S. 611 TO A GRAVEL ROAD EAST THENCE ABOUT 150 YARDS TO AN OLD HIGHWAY THENCE SOUTH 0.1 MILE, 21 FEET NORTH EAST OF THE CENTERLINE OF THE OLD HIGHWAY (OLD U.S. 611), 2 FEET SOUTH-SOUTH WEST OF STANDARD METAL WITNESS POST, 59 1/2 FEET NORTH-NORTH EAST OF RM 1, 67 FEET EAST OF RM 2, STANDARD TRIANGULATION STATION DISK SET IN TOP OF CONCRETE POST PROJECTING ABOUT 1 INCH ABOVE THE GROUND, STAMPED WANNA 1960. NOTE-- THIS IS ABOUT 0.2 MILE SOUTH OF THE WAYNE-MONROE COUNTY LINE. NOTE-- 0.4 MILE NORTH WEST OF THE AZIMUTH. TO REACH THE AZIMUTH FROM THE STATION GO ABOUT 0.1 MILE SOUTH EAST ON THE OLD HIGHWAY (U.S. 611) TO A GRAVEL ROAD THENCE LEFT ON U.S. 611 FOR 0.28 MILE.
01/01/1966 by CGS (SEE DESCRIPTION)
RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1966 (JLC) THE STATION MARK, REFERENCE MARKS NO. 1 AND 2 AND THE AZIMUTH MARK WERE RECOVERED IN GOOD CONDITION AND AS DESCRIBED IN 1960. LOCAL INGINEERS STATED THAT THE STATION MARK, REFERENCE MARKS NO. 1 AND 2 WOULD NOT BE IN THE WAY OF THE NEAR FUTURE CONSTRUCTION ALONG U.S. HIGHWAY 611, BUT THE AZIMUTH MARK WOULD POSSIBLY BE DESTROYED. DUE TO THE TIMBER IN THE AREA NO SUITABLE LOCATION WAS FOUND FOR ANOTHER AZIMUTH MARK. THE DISK WAS LEFT IN ITS ORIGINAL POSITION. THIS MARK ALSO BEING AN ELEVATION POINT IT WAS DEEMED NECESSARY TO ESTABLISH A NEW MARK. SEE DESCRIPTION OF BENCH MARK, WANNA AZI 1960 RESET.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in September 1999.
  • The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in June 1991.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
  • The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (g = 980.6199 gals.).
  • The modeled gravity was interpolated from observed gravity values.
