 LT0602.The horizontal coordinates were established by classical geodetic methods
 LT0602.and adjusted by the National Geodetic Survey in March 1994.
 LT0602.The horizontal coordinates are valid at the epoch date displayed above.
 LT0602.The epoch date for horizontal control is a decimal equivalence
 LT0602.of Year/Month/Day.
 LT0602
 LT0602.The NAVD 88 height was computed by applying the VERTCON shift value to
 LT0602.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 LT0602
 LT0602.The Laplace correction was computed from DEFLEC99 derived deflections.
 LT0602
 LT0602.The geoid height was determined by GEOID99.

 LT0602
 LT0602'DESCRIBED BY COAST AND GEODETIC SURVEY 1948 (WRH)
 LT0602'THE STATION IS ON A PROMINENT BRUSH COVERED HILL THAT IS KNOWN
 LT0602'AS HAYDEN HILL AND HAS A LOOKOUT ON IT BY THAT NAME.  IT IS
 LT0602'ABOUT 14 MILES SOUTH SOUTHEAST OF THE TOWN OF ADIN AND 20 MILES
 LT0602'SOUTHEAST OF THE TOWN OF BIEBER.
 LT0602'
 LT0602'THE STATION MARK, STAMPED HAYDEN HILL 1947, IS A STANDARD STATION
 LT0602'MARK DISK THAT IS CEMENTED IN A DRILL HOLE IN BEDROCK THAT
 LT0602'PROJECTS ABOUT 1 FOOT ABOVE THE GROUND.
 LT0602'
 LT0602'REFERENCE MARK NUMBER 1, STAMPED HAYDEN HILL NO 1 1947, IS A
 LT0602'STANDARD REFERENCE MARK DISK THAT IS SET IN A DRILL HOLE IN
 LT0602'OUTCROPPING BEDROCK THAT IS ABOUT 2-1/2 BY 5 FEET AND PROJECTS
 LT0602'ABOUT 2-1/2 FEET ABOVE THE GROUND.
 LT0602'
 LT0602'REFERENCE MARK NUMBER 2, STAMPED HAYDEN HILL NO 2 1947, IS
 LT0602'A STANDARD REFERENCE MARK DISK THAT IS SET IN A DRILL HOLE IN
 LT0602'A ROCK THAT IS ABOUT 3 BY 4 FEET AND PROJECTS ABOUT THE GROUND
 LT0602'ABOUT 4 FEET.
 LT0602'
 LT0602'THE AZIMUTH MARK, STAMPED HAYDEN HILL 1947, IS A STANDARD AZIMUTH
 LT0602'MARK DISK THAT IS CEMENTED IN A DRILL HOLE IN A LARGE, PROMINENT
 LT0602'BOULDER THAT IS ABOUT 5 BY 8 FEET AND PROJECTS ABOVE THE GROUND
 LT0602'ABOUT 5 FEET.  IT IS LOCATED ABOUT 150 FEET NORTHWEST OF THE
 LT0602'ROAD.
 LT0602'
 LT0602'THE STATION CAN BE REACHED FROM THE POST OFFICE IN ADIN BY
 LT0602'GOING SOUTH ON U.S. HIGHWAY 299 FOR 0.7 MILES TO A SIGN SUSANVILLE
 LT0602'74 AND A ROAD TO THE LEFT.  TURN LEFT ON THE ADIN-SUSANVILLE
 LT0602'ROAD AND FOLLOW THE MAIN TRAVELED ROAD TOWARD SUSANVILLE FOR
 LT0602'13.4 MILES TO A ROAD TO THE RIGHT AND A SIGN HAYDEN HILL.
 LT0602'CROSS THE CREEK AND FOLLOW THE MAIN TRAVELED ROAD UP THE HILL
 LT0602'FOR 4.1 MILES TO A SMALL SETTLEMENT.  TURN RIGHT AND FOLLOW THE
 LT0602'TRACK ROAD UP THE HILL FOR 0.4 MILE TO THE AZIMUTH MARK ON THE
 LT0602'LEFT.  CONTINUE UP THE HILL TO THE LOOKOUT AND THE STATION
 LT0602'ABOUT 100 YARDS TO THE NORTH.
 LT0602'
 LT0602'THE LOOKOUT IS AN ELEVATED BUILDING THAT SETS ON THE HIGHEST
 LT0602'POINT OF THE HILL.  IT IS ABOUT 20 FEET SQUARE AND IS WHITE IN
 LT0602'COLOR.
