Documented History (by the NGS)
|Unknown by (MONUMENTED)
|01/01/1929 by CGS (MONUMENTED)
|DESCRIBED BY COAST AND GEODETIC SURVEY 1929
STATION IS ON THE HIGHEST PART OF THE FIRST PROMINENT POINT OR HIGH BLUFF S OF FLINT ROCK, ABOUT 1 METER FROM THE EDGE OF THE BLUFF, WHICH IS THE NORTHERN FACE AND ALMOST PERPENDICULAR. THE STATION IS MARKED BY A BRONZE DISK IN CONCRETE, AS DESCRIBED IN NOTE 1A. IT IS SURROUNDED BY A LARGE ROCK CAIRN.
|01/01/1939 by CGS (MONUMENTED)
|RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1939 (IER)
STATION WAS ESTABLISHED IN 1871 BY A.W. CHASE AND RECOVERED AND MARKED IN 1914 BY H.A.S. STATION IS LOCATED ON THE HIGHEST PART OF THE FIRST PROMINENT POINT S OF FLINT ROCK. THE NORTHERN FACE OF THIS POINT IS ALMOST PERPENDICULAR BLUFF AND STATION IS ABOUT 2-1/2 FEET FROM EDGE OF BLUFF.
MARKED BY A STANDARD DISK SET IN BLOCK OF CONCRETE AND SURROUNDED BY A CAIRN OF ROCKS.
REFERENCE MARK IS A STANDARD DISK CEMENTED IN DRILL HOLE IN A ROCK 1-1/2 METERS S OF THE STATION.
THE STATION IS BEST REACHED BY TAKING THE HIGHWAY 101 S FROM THE TOWN OF KLAMATH TO THE POINT WHERE IT REACHES THE COAST LINE. AN OLD ROAD TURNS OFF TO THE NW AT THIS POINT. FOLLOW THIS OLD ROAD ABOUT 200 METERS TO THE FIRST POINT. THE POINT AND STATION ARE ABOUT 300 METERS W OF THE ROAD.
- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in March 1994. The horizontal coordinates are valid at the epoch date displayed above. The epoch date for horizontal control is a decimal equivalence of Year/Month/Day.
- The orthometric height was scaled from a topographic map.
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
