TO REACH FROM THE JUNCTION OF U.S. HIGHWAYS NOS. 219 AND 250, IN HUTTONSVILLE, GO SOUTH AND SOUTHEAST ON HIGHWAY 250 FOR 8.8 MILES TO SUMMIT OF MOUNTAIN GRADE AND A SIDE ROAD ON THE LEFT. TURN LEFT, GO NORTHERLY ON GRAVELED ROAD FOR 4.2 MILES TO A ROAD FORK. TAKE LEFT FORK, GO 1.35 MILES TO A WOODS ROAD ON THE RIGHT, AT TRIANGULAR BLAZES ON THE LEFT AND RIGHT.

TURN RIGHT, GO WESTERLY ALONG THE EDGE OF WOODS FOR 0.05 MILE TO WHERE A PHONE LINE ENTERS THE WOODS AT THE WEST END OF MEADOW. TURN RIGHT, GO WEST PICKING WAY THROUGH WOODS FOR 0.2 MILE TO THE HIGHEST PART OF HILL AND THE STATION. STATION MARKS ARE STANDARD DISKS STAMPED CHEAT 1957. THE SURFACE DISK IS SET IN A SQUARE CONCRETE POST WHICH PROJECTS 4 INCHES. IT IS 22 FEET EAST OF A TRIANGULAR BLAZE ON THE EAST SIDE OF A 10-INCH TREE, 19 FEET SOUTH-SOUTHWEST OF A TRIANGULAR BLAZE ON THE SOUTH SIDE OF A 10-INCH TREE, AND 14 FEET WEST OF A TRIANGULAR BLAZE ON THE EAST SIDE OF A 6-INCH TREE. A STANDARD WITNESS POST WAS SET 3 FEET WEST OF THE MARK. THE UNDERGROUND DISK IS SET IN AN IRREGULAR MASS OF CONCRETE 25 INCHES BELOW THE SURFACE OF THE GROUND. REFERENCE MARK NO. 1, A STANDARD DISK STAMPED CHEAT NO 1 1957, IS SET IN A SQUARE CONCRETE POST WHICH PROJECTS 6 INCHES.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in April 1998.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
