 LT0774.The horizontal coordinates were established by classical geodetic methods
 LT0774.and adjusted by the National Geodetic Survey in March 1994.
 LT0774.The horizontal coordinates are valid at the epoch date displayed above.
 LT0774.The epoch date for horizontal control is a decimal equivalence
 LT0774.of Year/Month/Day.
 LT0774
 LT0774.The NAVD 88 height was computed by applying the VERTCON shift value to
 LT0774.the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
 LT0774
 LT0774.The Laplace correction was computed from DEFLEC99 derived deflections.
 LT0774
 LT0774.The geoid height was determined by GEOID03.

 LT0774                          STATION DESCRIPTION
 LT0774
 LT0774'DESCRIBED BY COAST AND GEODETIC SURVEY 1948 (WRH)
 LT0774'THE STATION IS LOCATED NEAR BACKBONE LAKE, ON THE WEST SIDE OF
 LT0774'AN ABANDONED RANGER STATION, ABOUT 14 MILES, AIRLINE, SOUTH
 LT0774'OF BURNEY AND 11 MILES, AIRLINE, NORTH OF VIOLA.
 LT0774'
 LT0774'THE STATION MARK, STAMPED BONE 1948, IS A STANDARD DISK SET
 LT0774'IN A TRIANGULAR SHAPED BOULDER THAT PROJECTS 8 INCHES.  IT IS
 LT0774'51.6 FEET NORTHWEST OF THE NORTHWEST CORNER OF THE RANGER STATION
 LT0774'AND 20.0 FEET WEST OF THE CENTER OF THE DRIVEWAY.
 LT0774'
 LT0774'REFERENCE MARK NUMBER 1, STAMPED BONE NO 1 1948, IS A STANDARD
 LT0774'DISK SET IN A BOULDER THAT IS FLUSH WITH THE GROUND AND IS 1-1/2
 LT0774'FEET LOWER THAN THE STATION.  IT IS ON THE NORTH EDGE OF THE
 LT0774'DRIVEWAY.
 LT0774'
 LT0774'REFERENCE MARK NUMBER 2, STAMPED BONE NO 2 1948, IS A STANDARD
 LT0774'DISK SET IN A LARGE BOULDER THAT PROJECTS 8 INCHES AND IS
 LT0774'1 FOOT HIGHER THAN THE STATION.  IT IS 6.8 FEET WEST OF THE
 LT0774'NORTHWEST CORNER OF THE RANGER STATION.
 LT0774'
 LT0774'STATION BURNEY 1920 WILL SERVE AS THE AZIMUTH MARK.  TO REACH
 LT0774'SEE THE DESCRIPTION FOR BURNEY 1920.
 LT0774'
 LT0774'THE STATION IS REACHED AS FOLLOWS--FROM THE U.S. POST OFFICE
 LT0774'IN BURNEY GO SOUTHWEST ON U.S. HIGHWAY 299 FOR 1.0 MILE TO A
 LT0774'SIDE ROAD ON THE LEFT ON THE LEFT AT SCOTT LUMBER COMPANY
 LT0774'HILL.  TURN LEFT ON THE SIDE ROAD, CROSSING A BRIDGE, AND
 LT0774'FOLLOW THE MAIN ROAD SOUTHWEST AND SOUTH FOR 6.2 MILES TO A
 LT0774'FORK AND A SIGN SNOW MTN. PASS 15 1/2.  TAKE THE LEFT FORK
 LT0774'AND GO 0.6 MILE.  TAKE THE LEFT FORK AND GO 1.9 MILES.
 LT0774'CONTINUE STRAIGHT AHEAD FOR 0.9 MILE.  KEEP TO THE RIGHT AND GO
 LT0774'1.6 MILES.  TAKE THE LEFT FORK AS PER SIGN BACKBONE R.S.
 LT0774'7 AND GO 5.5 MILES TO A SIDE ROAD ON THE RIGHT.  TURN
 LT0774'RIGHT ON THE SIDE ROAD AND GO UPHILL FOR 1.5 MILES TO THE
 LT0774'END OF THE ROAD AND THE STATION.
 LT0774'
 LT0774'NOTE--THIS LAST 1.5 MILES IS NARROW AND STEEP.  THE ROAD IS
 LT0774'ABANDONED AND MIGHT HAVE TO BE CLEARED OF ROCKS AND SLIDES
 LT0774'TO MAKE THE STATION WITH A TRUCK.
