1.   Site Identification of the GNSS Monument

     Site Name                : Table Mountain Gravity Observatory
     Four Character ID        : TMGO
     Monument Inscription     :
     IERS DOMES Number        : 49433M001
     CDP Number               : (A4)
     Monument Description     : STEEL MAST
       Height of the Monument : 6
       Monument Foundation    : CONCRETE BLOCK/PILLAR
       Foundation Depth       : (m)
     Marker Description       : (CHISELLED CROSS/DIVOT/BRASS NAIL/etc)
     Date Installed           : 1994-07-06T00:00Z
     Geologic Characteristic  : (BEDROCK/CLAY/CONGLOMERATE/GRAVEL/SAND/etc)
       Bedrock Type           : (IGNEOUS/METAMORPHIC/SEDIMENTARY)
       Bedrock Condition      : (FRESH/JOINTED/WEATHERED)
       Fracture Spacing       : (1-10 cm/11-50 cm/51-200 cm/over 200 cm)
       Fault zones nearby     : (YES/NO/Name of the zone)
         Distance/activity    : (multiple lines)
     Additional Information   : The steel mast was the base section  of a 3
                              :  section radio mast. The upper two sections and
                              :  guy wires were removed before the station
                              :  station became a CORS. The radio mast was built
                              :  at the same time as the building in 1965.
                              :  The base mast ~6m.  Initially the GPS antenna
                              :  was mounted in the center of the three "poles".
                              :  and was then moved to the top of one leg see
                              :  section 4. At the same time the mast was braced
                              :  to the building. The depth of the pad or pillar
                              :  underlying the tower is unknown
                              :  IERS DOMES number added to log on 04-27-10.
                              : Site decommissioned 05-JUL-2023 replaced by TMG2
