 DC1879.The horizontal coordinates were established by classical geodetic methods
 DC1879.and adjusted by the National Geodetic Survey in June 1996.
 DC1879.The horizontal coordinates are valid at the epoch date displayed above.
 DC1879.The epoch date for horizontal control is a decimal equivalence
 DC1879.of Year/Month/Day.
 DC1879
 DC1879.The NAVD 88 height was computed by applying the VERTCON shift value to
 DC1879.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 DC1879
 DC1879.The Laplace correction was computed from DEFLEC99 derived deflections.
 DC1879
 DC1879.The geoid height was determined by GEOID99.

 DC1879                          STATION DESCRIPTION
 DC1879
 DC1879'DESCRIBED BY CA DIV OF HIGHWAYS 1958
 DC1879'STATION GORGE IS LOCATED ABOUT 9.2 AIR MILES - APPROXIMATE
 DC1879'BEARING N 55 DEG E - FROM THE TOWN OF JACUMBA.
 DC1879'
 DC1879'TO FIND THE STATION PROCEED AS FOLLOWS--
 DC1879'
 DC1879'STARTING FROM THE POST OFFICE IN JACUMBA, GO E ON U.S. HIGHWAY
 DC1879'80 (11.8 MI.) TO ENGR. STA. 315+35.  AT THIS POINT THERE IS
 DC1879'A GRAVEL ROAD TO THE RIGHT (NE).  THIS ROAD MAKES A LOOP
 DC1879'AROUND A ROCK HILL ABOUT 30 FT. HIGH AND COMES BACK INTO U.S.
 DC1879'HIGHWAY 80 ABOUT 100 FT. FARTHER ON.  NEAR THE MIDPOINT OF THIS
 DC1879'LOOP TURN RIGHT (NE) ON A ROAD WHICH LEADS DOWN INTO A SANDY
 DC1879'WASH AND DIRECTLY TOWARD A HIGH ROCKY HILL ABOUT 300 FT. AWAY.
 DC1879'AT THE BASE OF THE HILL TAKE A FOOT TRAIL WHICH TURNS E AND
 DC1879'THEN LOOPS BACK N AND UP THE W SLOPE OF THE HILL TO THE
 DC1879'HIGH POINT AND STATION GORGE (ABOUT 30-MIN. PACK).
 DC1879'
 DC1879'THE STATION DISK IS SET IN A LARGE BOULDER.  THE REFERENCE
 DC1879'MARKS ARE LOCATED AND SET AS SHOWN BY THE ABOVE DIRECTIONS,
 DC1879'DISTANCES AND NOTES.
