 OO0967
 OO0967.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 OO0967.been affixed to the stable North American tectonic plate. See 
 OO0967.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 OO0967
 OO0967.The horizontal coordinates are valid at the epoch date displayed above
 OO0967.which is a decimal equivalence of Year/Month/Day.
 OO0967
 OO0967.The orthometric height was determined by GPS observations and a
 OO0967.high-resolution geoid model.
 OO0967
 OO0967.GPS derived orthometric heights for airport stations designated as
 OO0967.PACS or SACS are published to 2 decimal places.  This maintains
 OO0967.centimeter relative accuracy between the PACS and SACS.  It does
 OO0967.not indicate centimeter accuracy relative to other marks which are
 OO0967.part of the published vertical control network.

 OO0914
 OO0914'RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1980 (CLN)
 OO0914'THE SURFACE STATION MARK, REFERENCE MARKS 1 AND 2 WERE RECOVERED IN
 OO0914'GOOD CONDITION.  THE AZIMUTH MARK WAS FOUND TILTED AND THE DISK WAS
 OO0914'SALVAGE.  AN AZIMUTH MARK 2 WAS ESTABLISHED.  THE DIRECTION TO
 OO0914'REFERENCE MARK 1 AGREED WITH 1934 DATA BUT THE DISTANCE WAS 3 FT (0.9
 OO0914'M) LONGER.  THE DIRECTION TO REFERENCE MARK 2 FAILED TO AGREE BUT THE
 OO0914'DISTANCE AGREED.  A FAVORABLE CHECK ANGLE WAS OBTAINED BETWEEN TWO OLD
 OO0914'DISTANT OBJECTS, THEREFORE, THE UNDERGROUND MARK WAS NOT INSPECTED.  A
 OO0914'NEW DESCRIPTION IS REQUIRED.
 OO0914'THE STATION IS ABOUT 6 MILES (9.7 KM) EAST OF NEW HAMPTON, 2-1/2 MILES
 OO0914'SOUTHWEST OF LAWER, IN A GRASSY STRIP BETWEEN TWO CULTIVATED FIELDS,
 OO0914'BETWEEN THE NE1/4, SEC13, AND THE SE1/4 SEC12, OF T95N, R12W.

 OO0914'LEFT AND THE AZIMUTH MARK 0.15 MILE (0.24 KM) WEST ALONG THAT ROAD.
 OO0914'CONTINUE SOUTH FOR 0.5 MILE (0.8 KM) TO WHERE THE ROAD TURNS SHARP
 OO0914'LEFT AND EAST AND THE END OF TRUCK TRAVEL.  WALK WEST ALONG A GRASSY
 OO0914'STRIP BETWEEN TWO CULTIVATED FIELDS FOR ABOUT 0.1 MILE (0.2 KM) TO THE
 OO0914'CREST OF THE HILL AND THE STATION.
 OO0914'SURFACE STATION MARK IS A STANDARD DISK, STAMPED---BENNETT 1934---,
 OO0914'SET IN THE TOP OF A ROUND CONCRETE POST PROJECTING 0.3 METER.  (1.0
 OO0914'FT) IT IS 0.3 METER (1.0 FT) NORTH OF A WITNESS POST.  REFERENCE MARK
 OO0914'1 IS A STANDARD DISK, STAMPED---BENNETT NO 1 1934---, SET IN THE TOP
 OO0914'OF A ROUND CONCRETE POST, PROJECTING 0.3 METER.  (1.0 FT) IT IS 0.3
 OO0914'METER (1.0 FT) WEST OF A WITNESS POST. REFERENCE MARK 2 IS A STANDARD

 NL0708'OPERATIONS.  A NEW SURFACE MARK WAS ESTABLISHED HOLDING THE EXACT
 NL0708'POSITION OF THE UNDERGROUND MARK AFTER THAT MARKS POSITION WAS
 NL0708'CHECKED FROM THE REFERENCE MARKS.  THE NEW SURFACE MARK WAS LEFT 14
 NL0708'INCHES BELOW THE GROUND SURFACE TO ALLOW FOR FARMING OPERATIONS.  THE
 NL0708'DISTANCE TO REFERENCE MARK 1 WAS 0.002 METER LONGER AND THE DISTANCE
 NL0708'TO REFERENCE MARK 3 WAS ALSO 0.002 METER LONGER WHILE THE DISTANCE
 NL0708'BETWEEN THE MARKS WAS ALSO 0.002 METER LONGER THAN 1972 DATA.  THE
 NL0708'DIRECTION FROM REFERENCE MARK 4 TO REFERENCE MARK 1 WAS 26 SECONDS
 NL0708'LARGER AND TO REFERENCE MARK 3 WAS 12 SECONDS LARGER THAN 1972 DATA.

 MJ1177                          STATION DESCRIPTION
 MJ1177
 MJ1177'DESCRIBED BY NATIONAL GEODETIC SURVEY 1981 (CLN)
 MJ1177'THE STATION IS LOCATED ABOUT 2 MILES NORTH AND 4 MILES WEST OF
 MJ1177'DEFIANCE, ON THE RIGHT-OF-WAY OF COUNTY ROUTE R.  IT IS 48 FEET SOUTH
 MJ1177'OF THE CENTER OF WHERE COUNTY ROUTE R CROSSES A NORTH-SOUTH OIL TOP
 MJ1177'ROAD, 8 FEET WEST-NORTHWEST OF A TELEPHONE POLE WITH A TRIANGLE BLAZE,
 MJ1177'6 FEET EAST-NORTHEAST OF A FENCE CORNER, AND 4 FEET NORTH OF A FENCE.
 MJ1177'
 MJ1177'THE SURFACE STATION MARK AND REFERENCE MARK 2 WERE FOUND BUT HAD
 MJ1177'OBVIOUSLY BEEN DISTURBED.  REFERENCE MARK 1 WAS FOUND DESTROYED.  THE
 MJ1177'AZIMUTH MARK WAS FOUND IN APPARENT GOOD CONDITION, HOWEVER, THE
 MJ1177'DIRECTION TO THE MARK WAS 10 DEGREES SMALLER THAN 1950 DATA.  A CHECK
 MJ1177'OF 6.1 SECONDS LARGER WAS OBTAINED BETWEEN THE WESTPHALIA ST BONIFACE
 MJ1177'CHURCH AND THE EARLING CATHOLIC CHURCH.  STATION MARK, REFERENCE MARK
 MJ1177'1 AND THE AZIMUTH MARK WERE IN THE WAY OF ROAD CONSTRUCTION,
 MJ1177'THEREFORE, STATION--DEFIANCE 2--, REFERENCE MARKS 3, 4 AND ANOTHER
 MJ1177'AZIMUTH MARK WERE ESTABLISHED.  REFERENCE MARK 2, ALTHOUGH VERY POOR,
 MJ1177'IS NOW A SHELBY COUNTY BENCH MARK AND WAS LEFT IN PLACE.  THE
 MJ1177'UNDERGROUND WAS ALSO LEFT IN PLACE BUT WILL PROBABLY BE DESTROYED.
 MJ1177'ALL 1981 OBSERVATIONS WERE TAKEN FROM THE UNDERGROUND MARK.  DISKS
 MJ1177'WERE SALVAGED FROM THE OLD SURFACE MARK, REFERENCE MARK 1 AND THE
 MJ1177'AZIMUTH MARK.

 MJ1177
 MJ1177'RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1982 (CLN)
 MJ1177'THE UNDERGROUND STATION MARK, DEFIANCE 2 AND DEFIANCE 2 AZ MK WERE
 MJ1177'RECOVERED IN GOOD CONDITION.  REFERENCE MARK 2 WAS RECOVERED IN POOR
 MJ1177'CONDITION AND WAS NOT USED.  SHELBY COUNTY USES THE MARK AS A BENCH
 MJ1177'MARK, THEREFORE IT WAS LEFT IN PLACE.  DUE TO GRADING CHANGES, THE NEW
 MJ1177'STATION WAS SITUATED IN A CULTIVATED FIELD, INSTEAD OF ON COUNTY ROAD
 MJ1177'RIGHT-OF-WAY.  THIS WAS NOT AGREEABLE WITH THE PROPERTY OWNER AND HE
 MJ1177'REQUESTED THAT DEFIANCE 2 AND DEFIANCE 2 RM 3 BE REMOVED.  THE
 MJ1177'POSITION OF THE ORIGINAL UNDERGROUND MARK WAS HELD AND A NEW
 MJ1177'UNDERGROUND MARK AND A NEW SURFACE MARK WERE THEN ESTABLISHED, AS THE
 MJ1177'ORIGINAL UNDERGROUND MARK WAS FOUND ONLY 0.15 M (0.49 FT) BELOW THE
 MJ1177'SURFACE.  REFERENCE MARK 5 WAS ALSO ESTABLISHED AND DEFIANCE 2
 MJ1177'REFERENCE MARK 4 NOW SERVES THE ORIGINAL STATION.  THE ARROW ON THIS
 MJ1177'MARK POINTS TOWARD DEFIANCE 2 UNDERGROUND MARK, WHICH WAS LEFT IN
 MJ1177'PLACE.  SATISFACTORY CHECKS ANGLES TO DISTANT OBJECTS WERE OBTAINED.

 AE2135.The horizontal coordinates are valid at the epoch date displayed above
 AE2135.which is a decimal equivalence of Year/Month/Day.
 AE2135
 AE2135.The orthometric height was determined by GPS observations and a
 AE2135.high-resolution geoid model.
 AE2135
 AE2135.GPS derived orthometric heights for airport stations designated as
 AE2135.PACS or SACS are published to 2 decimal places.  This maintains
 AE2135.centimeter relative accuracy between the PACS and SACS.  It does
 AE2135.not indicate centimeter accuracy relative to other marks which are
 AE2135.part of the published vertical control network.
 AE2135

 NL0712'SURFACE STATION MARK AND REFERENCE MARKS 1 AND 2 WERE RECOVERED IN
 NL0712'GOOD CONDITION.  AZIMUTH MARK WAS FOUND TO BE LOOSE WITH PART OF THE
 NL0712'DIRT DUG AWAY FROM TWO SIDES.  THE MARK WAS REINFORCED BY POURING
 NL0712'CONCRETE AROUND THE BASE OF THE MARK WHERE THE DIRT WAS MISSING.  THE
 NL0712'DISTANCES TO REFERENCE MARKS 1 AND 2 WERE 0.005 METER SHORTER AND
 NL0712'0.002 METER LONGER RESPECTIVELY THAN 1971 DATA.  THE DISTANCE BETWEEN
 NL0712'THE REFERENCE MARKS WAS 0.003 METER SHORTER THAN 1971 DATA.  THE
 NL0712'DIRECTION FROM THE LUVERNE MUN TANK TO REFERENCE MARK 1 WAS 31 SECONDS
 NL0712'LARGER AND TO REFERENCE MARK 2 WAS 1 MINUTE, 2 SECONDS LARGER THAN
 NL0712'1971 DATA.  AZIMUTH MARK WAS NOT OBSERVED UPON IN 1971.  THE DIRECTION
 NL0712'FROM THE AZIMUTH MARK TO THE LIVERMORE MUN TANK AND THE LUVERNE MUN
 NL0712'TANK DIFFERED FROM THE 1938 DATA BY 6 MINUTES, 29.1 SECONDS AND 6
 NL0712'MINUTES, 21.9 SECONDS RESPECTIVELY WHILE THE ANGLE BETWEEN THE TWO
 NL0712'TANKS DIFFERED BY 7.2 SECONDS LARGER THAN 1938 DATA INDICATING THE

 NL0663'FOUND, MO. R.C. STATION KENNEBEC DIRECTLY UNDER YOUR STATION
 NL0663'HATHOWAY.  IT IS A STONE 18 IN X 18 IN X 3 IN WITH A COPPER
 NL0663'BOLT SET IN CENTER OF STONE.  THERE IS NO INDICATION THAT
 NL0663'THE STONE OF THE ORIGINAL STATION KENNEBEC HAS BEEN DISTURBED.
 NL0663'THE ORIGNAL PIPE PLACED OVER THIS STONE HAS BEEN REMOVED AND
 NL0663'WAS FOUND AT THE FOOT OF THE HILL.  THE CONCRETE OF YOUR

 NL0663'KENNEBEC.  IT IS NOT POSSIBLE TO LOCATED THE MARK ON THIS
 NL0663'STONE WITHOUT CHIPPING AWAY THE CONCRETE AND DISTURBING
 NL0663'YOUR MONUMENT.  HOWEVER, BY MEASURMENTS TO CORNERS OF THE STONE,
 NL0663'IT IS APPARENT THAT THE STATION HATHOWAY IS WITHIN 0.1
 NL0663'FOOT OF A POINT DIRECTLY OVER THE CENTER OF THE STONE OF
 NL0663'THE ORIGINAL STATION KENNEBEC.  THE ORIGINAL POINT MAY NOT BE
 NL0663'AT THE EXACT CENTER OF THE STONE.

 NL0663'THE STATION WAS RECOVERED AND ALL MARKS FOUND IN GOOD CONDITION.
 NL0663'A NEW DESCRIPTION FOLLOWS.
 NL0663'
 NL0663'THE STATION IS LOCATED ABOUT 5.5 MILES E AND 3.0 MILES N
 NL0663'OF THE VILLAGE OF ONAWA ON THE OLD HATHOWAY FARM WHICH IS
 NL0663'NOW VACANT.  NOTHING IS LEFT OF THE OLD HATHOWAY HOME SITE
 NL0663'EXCEPT A LONE WINDMILL TOWER.  THE STATION IS ABOUT 300
 NL0663'YARDS E OF THE OLD TOWER ON THE HIGHEST POINT OF THE BLUFF.
 NL0663'
 NL0663'THIS STATION WAS RECOVERED IN AN EFFORT TO TRAVERSE TO MO.
 NL0663'R.C. STATION KENNEBEC AND A THOROUGH SEARCH WAS MADE WITHOUT
 NL0663'RESULTS.  A BENCH WAS ESTABLISHED OVER STATION HATHOWAY AND
 NL0663'A POINT SET DIRECTLY OVER THE SURFACE MARK, THEN THE SURFACE
 NL0663'MARK WAS REMOVED IN ORDER TO INVESTIGATE THE SUBSURFACE
 NL0663'MARK.
 NL0663'
 NL0663'THE SUBSURFACE MARK WAS FOUND TO BE A BRONZE STATION DISK
 NL0663'SET IN THE CENTER OF AN 18-INCH SQUARE LIMESTONE BLOCK AND
 NL0663'THE DISK WAS STAMPED HATHOWAY 1934.  THIS SUBSURFACE MARK
 NL0663'WAS FOUND TO BE PLUMB WITH THE SURFACE MARK.  THE SURFACE
 NL0663'MARK WAS REESTABLISHED IN THE EXACT LOCATION AS ORIGINALLY
 NL0663'FOUND.

 NL0734'WERE RECOVERED IN GOOD CONDITION.  REFERENCE MARK 2 HAS BEEN
 NL0734'COVERED OVER BY THE DAKOTA CITY MUNICIPAL BUILDING.  THE
 NL0734'PREVIOUS MEASUREMENT TO REFERENCE MARK 1 WAS CHECKED, THE
 NL0734'MEASUREMENT TO THE WATER TANK WAS NOT CHECKED DUE TO BUILDING
 NL0734'ON LINE.  NO NEW MARKS WERE ESTABLISHED AT THIS TIME.  A
 NL0734'COMPLETE NEW DESCRIPTION FOLLOWS.
 NL0734'
 NL0734'THE STATION IS LOCATED IN THE CENTER OF DAKOTA CITY, ON
 NL0734'THE WEST SIDE OF MAIN STREET, BETWEEN MILL AND BROADWAY
 NL0734'STREETS, AT THE MUNICIPAL BUILDING AND WATER TANK, IN A LAWN
 NL0734'OWNED BY THE CITY.
 NL0734'
 NL0734'THE STATION MARKS ARE STANDARD DISKS STAMPED HUMBOTA 1938.
 NL0734'THE SURFACE DISK IS SET IN THE TOP OF A 12-INCH SQUARE CONCRETE
 NL0734'MONUMENT WHICH IS FLUSH WITH THE GROUND.  IT IS 53 FEET
 NL0734'WEST OF THE CENTER OF MAIN STREET, 37.1 FEET SOUTH OF THE
 NL0734'SOUTHEAST CORNER OF THE MUNICIPAL BUILDING, 10.4 FEET WEST
 NL0734'OF THE WEST EDGE OF A SIDEWALK, AND 8.8 FEET SOUTHWEST OF
 NL0734'A 24-INCH TREE.  THE 1938 DESCRIPTION STATES THAT THE
 NL0734'UNDERGROUND DISK IS SET IN THE TOP OF AN IRREGULAR MASS OF
 NL0734'CONCRETE.
 NL0734'
 NL0734'REFERENCE MARK 1, A STANDARD DISK STAMPED HUMBOTA NO 1 1938,
 NL0734'IS SET IN THE TOP OF A 12-INCH SQUARE CONCRETE MONUMENT WHICH
 NL0734'IS 1 INCH BELOW GROUND.  IT IS 37 FEET NORTH OF THE CENTER
 NL0734'OF BROADWAY STREET, 13.7 FEET EAST OF A 16-INCH ELM TREE, AND
 NL0734'7 FEET WEST OF A 24-INCH ELM TREE.
 NL0734'
 NL0734'THE AZIMUTH MARK, A STANDARD DISK STAMPED HUMBOTA 1938, IS
 NL0734'SET IN THE TOP OF A 12-INCH SQUARE CONCRETE MONUMENT WHICH
 NL0734'PROJECTS 1 INCH ABOVE GROUND.  IT IS 41.5 FEET EAST OF THE
 NL0734'CENTER OF MAIN STREET, 26.7 FEET EAST OF A 4 X 4 INCH RAILROAD
 NL0734'CROSSING SIGNPOST, AND 14.3 FEET SOUTH OF THE SOUTH RAIL
 NL0734'OF A SINGLE RAILROAD TRACK.
 NL0734'
 NL0734'TO REACH THE AZIMUTH MARK FROM THE STATION, GO NORTH ON
 NL0734'MAIN STREET FOR 0.55 MILE TO THE RAILROAD TRACK AND THE MARK
 NL0734'ON THE RIGHT.
 NL0734'
 NL0734'BECAUSE OF LARGE TREES CLOSE TO THE STATION, AN ECCENTRIC
 NL0734'POINT WAS SET 23.8 FEET TO THE SOUTHWEST.  THE TOWER WAS
 NL0734'BUILT OVER THIS POINT.

 NL0895
 NL0895'DESCRIBED BY COAST AND GEODETIC SURVEY 1934 (CAS)
 NL0895'THE STATION IS THE CENTER OF THE WOODEN MUNICIPAL WATER TANK
 NL0895'OF LAURENS.  THIS TANK IS LOCATED ABOUT 28 FEET N AND ABOUT 10
 NL0895'FEET E OF THE CENTER OF THE STEEL MUNICIPAL TANK OF LAURENS.
 NL0895'
 NL0895'THIS TANK IS A WOODEN TANK BUILT ON FOUR-LEGGED STEEL STRUCTURE.
 NL0895'THE BOTTOM OF THE TANK IS FLAT AND IS ABOUT 80 FEET ABOVE THE
 NL0895'GROUND.  IT IS CYLINDRICAL AND HAS A CONICAL ROOF OF LITTLE
 NL0895'PITCH.  THE TANK IS PAINTED BLACK.  THE STRUCTURE SUPPORTING
 NL0895'THE TANK WAS BUILT IN 1900.  THE PRESENT WOOD TANK WAS BUILT
 NL0895'ON THIS FRAMEWORK IN 1930.  FROM MOST DIRECTIONS THIS TANK CAN
 NL0895'BE DISTINGUISHED FROM THE STEEL TANK JUST S OF IT BY ITS FLAT
 NL0895'BOTTOM, ITS GREATER DIAMETER AND ITS LESS HEIGHT.

 NL0901.The horizontal coordinates were established by GPS observations
 NL0901.and adjusted by the National Geodetic Survey in June 2012.
 NL0901
 NL0901.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 NL0901.been affixed to the stable North American tectonic plate. See 
 NL0901.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 NL0901
 NL0901.The horizontal coordinates are valid at the epoch date displayed above
 NL0901.which is a decimal equivalence of Year/Month/Day.
 NL0901
 NL0901.The orthometric height was determined by GPS observations and a
 NL0901.high-resolution geoid model.
 NL0901
 NL0901.GPS derived orthometric heights for airport stations designated as
 NL0901.PACS or SACS are published to 2 decimal places.  This maintains
 NL0901.centimeter relative accuracy between the PACS and SACS.  It does
 NL0901.not indicate centimeter accuracy relative to other marks which are
 NL0901.part of the published vertical control network.

 MH0588
 MH0588'RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1975 (CLN)
 MH0588'THIS DATE THE PROPERTY OWNERS, MR. D.A. AND MRS. MARY A. COOK WERE
 MH0588'CONTACTED AND WOULD ASSIST IN THE RECOVERY OF THE STATION MARK BEING
 MH0588'THE OLD TIES ARE GONE IN THE AREA, BUT THE AREA IS IN BEANS THIS
 MH0588'DATE AND THE SEARCH FOR THE STATION MARK WOULD NEED TO TAKE PLACE
 MH0588'WHEN THE CROP IS HARVESTED.  REFERENCE MARK 1 WAS NOT FOUND AND IT
 MH0588'IS BELIEVED THE MARK WAS DESTROYED BY ROAD CONSTRUCTION.  THE TOP
 MH0588'PART OF THE REFERENCE MARK 2 CONCRETE MONUMENT WITH DISK WAS
 MH0588'FOUND ON TOP THE GROUND IN A FENCELINE.

 AE9184.This is a reference station for the NORTH LIBERTY
 AE9184.National Continuously Operating Reference Station (NLIB).
 AE9184
 AE9184.The horizontal coordinates were established by GPS observations
 AE9184.and adjusted by the National Geodetic Survey in June 2012.
 AE9184
 AE9184.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AE9184.been affixed to the stable North American tectonic plate. See 
 AE9184.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AE9184
 AE9184.The horizontal coordinates are valid at the epoch date displayed above
 AE9184.which is a decimal equivalence of Year/Month/Day.
 AE9184
 AE9184.The orthometric height was determined by differential leveling and
 AE9184.adjusted by the NATIONAL GEODETIC SURVEY
 AE9184.in July 2002.
 AE9184
 AE9184.Significant digits in the geoid height do not necessarily reflect accuracy.
 AE9184.GEOID18 height accuracy estimate available here.
 AE9184
 AE9184.Click photographs - Photos may exist for this station.
 AE9184
 AE9184.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AE9184
 AE9184.The Laplace correction was computed from DEFLEC18 derived deflections.
 AE9184
 AE9184.The ellipsoidal height was determined by GPS observations
 AE9184.and is referenced to NAD 83.
 AE9184
 AE9184.The dynamic height is computed by dividing the NAVD 88
 AE9184.geopotential number by the normal gravity value computed on the
 AE9184.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 AE9184.degrees latitude (g = 980.6199 gals.).
 AE9184
 AE9184.The modeled gravity was interpolated from observed gravity values.

 MG0916.This is a reference station for the NORTH LIBERTY
 MG0916.National Continuously Operating Reference Station (NLIB).
 MG0916
 MG0916.The horizontal coordinates were established by GPS observations
 MG0916.and adjusted by the National Geodetic Survey in June 2012.
 MG0916
 MG0916.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 MG0916.been affixed to the stable North American tectonic plate. See 
 MG0916.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 MG0916
 MG0916.The horizontal coordinates are valid at the epoch date displayed above
 MG0916.which is a decimal equivalence of Year/Month/Day.
 MG0916
 MG0916.The orthometric height was determined by differential leveling and
 MG0916.adjusted by the NATIONAL GEODETIC SURVEY
 MG0916.in July 2002.

 MG0916.The Laplace correction was computed from DEFLEC18 derived deflections.
 MG0916
 MG0916.The ellipsoidal height was determined by GPS observations
 MG0916.and is referenced to NAD 83.
 MG0916
 MG0916.The dynamic height is computed by dividing the NAVD 88
 MG0916.geopotential number by the normal gravity value computed on the
 MG0916.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 MG0916.degrees latitude (g = 980.6199 gals.).

 AJ8292.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AJ8292.been affixed to the stable North American tectonic plate. See 
 AJ8292.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AJ8292
 AJ8292.The horizontal coordinates are valid at the epoch date displayed above
 AJ8292.which is a decimal equivalence of Year/Month/Day.
 AJ8292
 AJ8292.The orthometric height was determined by GPS observations and a
 AJ8292.high-resolution geoid model.
 AJ8292
 AJ8292.GPS derived orthometric heights for airport stations designated as
 AJ8292.PACS or SACS are published to 2 decimal places.  This maintains
 AJ8292.centimeter relative accuracy between the PACS and SACS.  It does
 AJ8292.not indicate centimeter accuracy relative to other marks which are
 AJ8292.part of the published vertical control network.

 MH0654
 MH0654'RECOVERY NOTE BY IOWA GEODETIC SURVEY 1934
 MH0654'STATION WAS FOUND AS DESCRIBED WITH BOTH REFERENCE MARKS AND
 MH0654'THE STATION ITSELF IN GOOD CONDITION.  A U.S. COAST AND
 MH0654'GEODETIC SURVEY AND STATE SURVEY TRAVERSE STATION WAS ESTABLISHED
 MH0654'1276 FEET NORTH-NORTHEAST OF THE PALMYRA TRIANGULATION STATION.
 MH0654'THE STATION IS A BRASS TABLET SET IN CONCRETE FLUSH WITH THE
 MH0654'GROUND.  IT IS ABOUT 1/4 MILE WEST OF THE PALMYRA STORE ON
 MH0654'THE WEST SIDE OF THE PALMYRA-INDIANOLA ROAD, 24 FEET FROM
 MH0654'THE CENTER LINE AND 12 FEET SOUTH FROM THE CENTER LINE OF
 MH0654'THE ROAD RUNNING EAST INTO PALMYRA.

 MH0654
 MH0654'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1958 (REW)
 MH0654'THE STATION MARK AND REFERENCE MARK 2 WERE RECOVERED AND FOUND
 MH0654'TO BE IN GOOD CONDITION.  A ROUGH DISTANCE CHECK WAS MADE FROM
 MH0654'REFERENCE MARK 2 TO THE STATION TO ENABLE THE RECOVERY OF
 MH0654'THE STATION MARK, WHICH WAS EASILY FOUND.  REFERENCE MARK 1
 MH0654'WAS DESTROYED DURING ROAD IMPROVEMENTS.  THE DISK WAS REMOVED
 MH0654'FROM THE POST AND BROUGHT IN.  AN INSTRUMENT SET UP WAS
 MH0654'NOT MADE SO THE DIRECTION TO REFERENCE MARK 2 WAS NOT VERIFIED.
 MH0654'THE OLD ROUTE TO THE STATION IS NOW OBSOLETE AND A NEW ONE
 MH0654'FOLLOWS.
 MH0654'
 MH0654'TO REACH THE STATION FROM THE STORE IN PALMYRA GO WEST ON
 MH0654'THE GRAVELED ROAD FOR 0.3 MILE TO A T INTERSECTION.  TURN
 MH0654'LEFT AND GO SOUTH FOR 0.2 MILE TO WHERE THE ROAD TURNS RIGHT.
 MH0654'TURN RIGHT AND GO 0.05 MILE TO THE STATION ON THE RIGHT,
 MH0654'NORTH, SIDE OF THE ROAD.

 MH0654
 MH0654'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1963 (RCY)
 MH0654'THE STATION WAS RECOVERED IN GOOD CONDITION.  REFERENCE MARK
 MH0654'NO. 1 COULD NOT BE FOUND AND WAS PROBABLY DESTROYED BY DITCH
 MH0654'GRADING.  REFERENCE MARK NO. 2 WAS NOT LOOKED FOR.  THE
 MH0654'LAND ON WHICH THE STATION IS LOCATED IS NOW OWNED BY MR.
 MH0654'CHARLES CRAIG.
 MH0654'
 MH0654'A TO REACH DESCRIPTION FOLLOWS--TO REACH FROM THE T-ROAD
 MH0654'INTERSECTION IN PALMYRA GO WESTERLY FOR 0.35 MILE TO T-ROAD,
 MH0654'TURN LEFT (SOUTH) AND GO 0.25 MILE TO CURVE IN ROAD, TURN RIGHT
 MH0654'(WEST) TO STATION IN FIELD ON RIGHT AS DESCRIBED.

 MH0654                          STATION RECOVERY (1979)
 MH0654
 MH0654'RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1979 (CLN)
 MH0654'THE STATION SIGHT WAS VISITED BUT THE FIELD WAS STILL IN CROPS AND THE
 MH0654'PROPERTY OWNER, MR. CHARLES CRAIG, COULD NOT BE LOCATED.  REFERENCE
 MH0654'MARK 2 WAS SEARCHED FOR BUT NOT FOUND.  THE STATE SURVEY TRAVERSE
 MH0654'STATION THAT WAS ESTABLISHED IN 1934 WAS ALSO SEARCHED FOR BUT NOT
 MH0654'FOUND.  IN ALL PROBABILITY THE STATION STILL EXISTS AND THE SITE WILL
 MH0654'BE RE-VISITED IN THE FUTURE IN ORDER TO ESTABLISH NEW REFERENCE MARKS
 MH0654'AND AN AZIMUTH MARK.

 MJ1441.The horizontal coordinates were established by GPS observations
 MJ1441.and adjusted by the National Geodetic Survey in June 2012.
 MJ1441
 MJ1441.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 MJ1441.been affixed to the stable North American tectonic plate. See 
 MJ1441.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 MJ1441
 MJ1441.The horizontal coordinates are valid at the epoch date displayed above
 MJ1441.which is a decimal equivalence of Year/Month/Day.
 MJ1441
 MJ1441.The orthometric height was determined by GPS observations and a
 MJ1441.high-resolution geoid model.
 MJ1441
 MJ1441.GPS derived orthometric heights for airport stations designated as
 MJ1441.PACS or SACS are published to 2 decimal places.  This maintains
 MJ1441.centimeter relative accuracy between the PACS and SACS.  It does
 MJ1441.not indicate centimeter accuracy relative to other marks which are
 MJ1441.part of the published vertical control network.

 NL0877'AZIMUTH MARK FROM THE REFERENCE MARKS, AND A THOROUGH SEARCH
 NL0877'WAS MADE ON BOTH SIDES OF HIGHWAY, BUT NO EVIDENCE COULD
 NL0877'BE FOUND.  AS ORIGINALLY DESCRIBED, THE MARK WOULD BE IN THE
 NL0877'MIDDLE OF THE DITCH, AND, THEREFORE, SHOULD BE LISTED AS
 NL0877'DESTROYED.

 LF1496.The horizontal coordinates were established by GPS observations
 LF1496.and adjusted by the National Geodetic Survey in June 2012.
 LF1496
 LF1496.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 LF1496.been affixed to the stable North American tectonic plate. See 
 LF1496.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 LF1496
 LF1496.The horizontal coordinates are valid at the epoch date displayed above
 LF1496.which is a decimal equivalence of Year/Month/Day.
 LF1496
 LF1496.The orthometric height was determined by GPS observations and a
 LF1496.high-resolution geoid model.
 LF1496
 LF1496.GPS derived orthometric heights for airport stations designated as
 LF1496.PACS or SACS are published to 2 decimal places.  This maintains
 LF1496.centimeter relative accuracy between the PACS and SACS.  It does
 LF1496.not indicate centimeter accuracy relative to other marks which are
 LF1496.part of the published vertical control network.
 LF1496
 LF1496.Significant digits in the geoid height do not necessarily reflect accuracy.

 AI1965.The horizontal coordinates were established by GPS observations
 AI1965.and adjusted by the National Geodetic Survey in June 2012.
 AI1965
 AI1965.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AI1965.been affixed to the stable North American tectonic plate. See 
 AI1965.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AI1965
 AI1965.The horizontal coordinates are valid at the epoch date displayed above
 AI1965.which is a decimal equivalence of Year/Month/Day.
 AI1965
 AI1965.The orthometric height was determined by GPS observations and a
 AI1965.high-resolution geoid model.
 AI1965
 AI1965.GPS derived orthometric heights for airport stations designated as
 AI1965.PACS or SACS are published to 2 decimal places.  This maintains
 AI1965.centimeter relative accuracy between the PACS and SACS.  It does
 AI1965.not indicate centimeter accuracy relative to other marks which are
 AI1965.part of the published vertical control network.

 NM0113.The horizontal coordinates were established by GPS observations
 NM0113.and adjusted by the National Geodetic Survey in June 2012.
 NM0113
 NM0113.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 NM0113.been affixed to the stable North American tectonic plate. See 
 NM0113.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 NM0113
 NM0113.The horizontal coordinates are valid at the epoch date displayed above
 NM0113.which is a decimal equivalence of Year/Month/Day.
 NM0113
 NM0113.The orthometric height was determined by differential leveling and
 NM0113.adjusted by the NATIONAL GEODETIC SURVEY
 NM0113.in June 1991.
 NM0113
 NM0113.Significant digits in the geoid height do not necessarily reflect accuracy.

 NM0113
 NM0113.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 NM0113
 NM0113.The Laplace correction was computed from DEFLEC18 derived deflections.
 NM0113
 NM0113.The ellipsoidal height was determined by GPS observations
 NM0113.and is referenced to NAD 83.
 NM0113
 NM0113.The dynamic height is computed by dividing the NAVD 88
 NM0113.geopotential number by the normal gravity value computed on the
 NM0113.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 NM0113.degrees latitude (g = 980.6199 gals.).
 NM0113
 NM0113.The modeled gravity was interpolated from observed gravity values.

 NJ0544'THE RAILROAD DISTANCE FROM V 80 INDICATES THE BLAIRS FERRY ROAD
 NJ0544'CROSSING. THE TRACKS WERE RECENTLY TORN OUT FROM THIS LOCALITY AND
 NJ0544'CONSIDERABLE RE-GRADING HAS BEEN DONE IN CONNECTION WITH WIDENING
 NJ0544'BLAIRS FERRY, EXPANDING BUSINESSES ALONG THE OLD RR RIGHT OF WAY, AND
 NJ0544'ADDING A SIDEWALK ALONG BLAIRS FERRY.
 NJ0544'
 NJ0544'ABOUT 70 YARDS FROM THE CROSSING ENE ALONG THE OLD RAILROAD ROUTE, AND
 NJ0544'DOWN THE RE-GRADED BANK ON THE NORTHERLY SIDE, IS THE END OF AN OLD 2
 NJ0544'FOOT CAST IRON CULVERT. THE SOUTHERLY END CAN BE SEEN THROUGH A
 NJ0544'MANHOLE ACCESS IN A NEW CONCRETE BOX ADJACENT TO BLAIRS FERRY ROAD
 NJ0544'WHICH CONNECTS TO A CULVERT UNDER THE ROAD. THE OLD CULVERT TERMINATES
 NJ0544'FLUSH WITH THE INSIDE OF THE BOX ABOUT 6 FEET BELOW THE SURFACE.
 NJ0544'
 NJ0544'THE OLD CONCRETE HEADWALL IS OR WAS JUST NORTH OF THE NEW BOX. THE
 NJ0544'DISK COULD BE BURIED THERE, BUT IS MOST LIKELY GONE GIVEN THE BROKEN
 NJ0544'CONDITION OR NEAR LACK OF CONCRETE ON OTHER CULVERTS ALONG THIS RAIL
 NJ0544'LINE.
