 MW0854.The horizontal coordinates were established by classical geodetic methods
 MW0854.and adjusted by the National Geodetic Survey in March 1994.
 MW0854.The horizontal coordinates are valid at the epoch date displayed above.
 MW0854.The epoch date for horizontal control is a decimal equivalence
 MW0854.of Year/Month/Day.
 MW0854
 MW0854.The NAVD 88 height was computed by applying the VERTCON shift value to
 MW0854.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 MW0854
 MW0854.The Laplace correction was computed from DEFLEC99 derived deflections.
 MW0854
 MW0854.The geoid height was determined by GEOID99.

 MW0854
 MW0854'DESCRIBED BY COAST AND GEODETIC SURVEY 1920 (EWE)
 MW0854'ABOUT 20 MILES NORTH OF BIEBER, 13 MILES NORTH OF LOOKOUT
 MW0854'POST OFFICE, 4 MILES (BY TRAIL) SOUTHEAST OF HAPPY CAMP RANGER
 MW0854'STATION, ON HIGHEST POINT OF TURRET MOUNTAIN, AND 9 METERS
 MW0854'(30 FEET) WEST OF FOREST SERVICE LOOKOUT HAPPY CAMP.  MARKED BY
 MW0854'STANDARD STATION DISK IN BEDROCK, NOTE 2.  REFERENCE MARK NO.
 MW0854'1 IS STANDARD REFERENCE IN CONCRETE FOUNDATION OF LOOKOUT
 MW0854'HOUSE, AND 9.05 METERS (29.7 FEET) FROM STATION IN AZIMUTH
 MW0854'273 DEG 54 MIN.  REFERENCE MARK NO. 2 IS STANDARD REFERENCE
 MW0854'DISK IN BEDROCK, NOTE 12A, 8.10 METERS (26.6 FEET) FROM
 MW0854'STATION IN AZIMUTH 106 DEG 44 MIN.

 MW0854
 MW0854'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1947 (SPH)
 MW0854'THE STATION MARK HAS BEEN REMOVED.  THE ORIGINAL POSITION MUST
 MW0854'BE CONSIDERED LOST.  THE TOP OF THE MOUNTAIN HAS BEEN BLASTED
 MW0854'AND LEVELED OFF TO PERMIT THE BUILDING OF THE U.S. FOREST SERVICE
 MW0854'LOOKOUT HAPPY CAMP, AND IT IS BELIEVED THE ROCK IN WHICH THE
 MW0854'STATION MARK WAS SET WAS SHATTERED.  THE RECONNAISSANCE PARTY OF
 MW0854'NORMAN E. SYLAR RECOVERED THE MARK EARLY IN 1947, AND BELIEVED
 MW0854'IT TO BE IN ITS ORIGINAL POSITION, ALTHOUGH THE ROCK WAS
 MW0854'BADLY CRACKED.  LATER THE MARK WAS FOUND IN A SMALL
 MW0854'FRAGMENT OF ROCK, AND ITS FORMER POSITION UNKNOWN.
 MW0854'
 MW0854'BOTH REFERENCE MARKS ARE ALSO BELIEVED LOST, ALTHOUGH IT IS
 MW0854'POSSIBLE THAT NO. 1 IS UNDER THE PORCH OF THE LOOKOUT HOUSE.
 MW0854'
 MW0854'NO SUITABLE PLACE IN THE IMMEDIATE VICINITY COULD BE FOUND TO
 MW0854'REESTABLISH THE STATION.  A NEW STATION, HAPPY, WAS ESTABLISHED
 MW0854'ABOUT 1/2 MILE NORTHWEST OF THE LOOKOUT, AND AN AZIMUTH MARK
 MW0854'WAS SET NEAR THE POSITION OF THE OLD STATION.
