Documented History (by the NGS)
|01/01/1934 by CGS (MONUMENTED)
|DESCRIBED BY COAST AND GEODETIC SURVEY 1934
19.5 MI W FROM CAMERON. ABOUT 19.5 MILES WEST ALONG STATE HIGHWAY 64 FROM CAMERON, COCONINO COUNTY, ABOUT 50 YARDS EAST OF A 2-FOOT GALVANIZED-IRON CULVERT, AT THE EAST RIM OF A DEEP CANYON, ABOUT 70 FEET NORTH OF THE WEST END OF A CUT, 89 FEET NORTH OF THE CENTER LINE OF THE HIGHWAY, AND IN THE TOP OF A LIMESTONE LEDGE. A STANDARD DISK, STAMPED M 62 1934.
|01/01/1977 by NGS (GOOD)
|RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1977
THE STATION WAS RECOVERED AND FOUND IN GOOD CONDITION. A NEW DESCRIPTION FOLLOWS-- TO REACH THE STATION FROM CAMERON, TRAVEL SOUTH ON U.S. HWY. 89 FOR ABOUT 1 MILE TO JUNCTION WITH STATE ROUTE 64, GO WEST ON HWY. 64 FOR 16 MILES TO MILE POST 280, ABOUT 100 FEET BEFORE YOU REACH THE MILE POST, TURN LEFT, AND GO TO OLD HWY., TURN RIGHT ON OLD HWY. AND GO 1.90 MILES TO STATION ON THE RIGHT ABOUT 50 YARDS EAST OF A 2 FOOT GALVANIZED-IRON CULVERT, AT THE EAST RIM OF A DEEP CANYON, ABOUT 70 FEET NORTH OF THE WEST END OF A CUT, 89 FEET NORTH OF CENTERLINE OF HWY., AND IN THE TOP OF A LIMESTONE LEDGE ABOUT 3 FEET HIGHER THAN HWY. NOTE-- FUTURE WORK ON REALIGNMENT OF STATE HWY. 64 WILL CHANGE MILEAGE.
- The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.
- The orthometric height was determined by differential leveling and adjusted by the National Geodetic Survey in 1992. * This is a POSTED BENCH MARK height. Code A indicates a distribution rate of 0.0 thru 1.0 mm/km.
- The geoid height was determined by GEOID99.
- The dynamic height is computed by dividing the NAVD 88 geopotential number by the normal gravity value computed on the Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 degrees latitude (G = 980.6199 gals.).
- The modeled gravity was interpolated from observed gravity values.
