 DC1964.The horizontal coordinates were established by classical geodetic methods
 DC1964.and adjusted by the National Geodetic Survey in June 1996.
 DC1964.The horizontal coordinates are valid at the epoch date displayed above.
 DC1964.The epoch date for horizontal control is a decimal equivalence
 DC1964.of Year/Month/Day.
 DC1964
 DC1964.The NAVD 88 height was computed by applying the VERTCON shift value to
 DC1964.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 DC1964
 DC1964.The Laplace correction was computed from DEFLEC99 derived deflections.
 DC1964
 DC1964.The geoid height was determined by GEOID99.

 DC1964'DESCRIBED BY US ENGINEERS 1940
 DC1964'STATION IS STANDARD DISK IN BOULDER ON SECOND LARGEST AND SOUTHERN
 DC1964'BOULDER ON TOP OF HILL.
 DC1964'
 DC1964'IT IS LOCATED ON A HIGH BOULDER COVERED HILL ON THE SOUTHWEST EDGE OF
 DC1964'MASON VALLEY.  HILL IS ON THE NORTHERN SLOPE OF A STEEP SIDE RIDGE
 DC1964'RUNNING NORTH FROM THE MAIN RIDGE, WHICH IS THE HIGHEST RIDGE
 DC1964'RUNNING NORTH FROM MASON VALLEY.  THE HILL IS THE HIGHEST ONE
 DC1964'SETTING SOUTHEAST FROM A GROUP OF RANCH BUILDINGS, THE ONLY
 DC1964'RANCH IN THIS SECTION OF THE VALLEY.
