     Four Character ID        : STJ2
     Monument Inscription     : M090000
     IERS DOMES Number        : 40101M004
     CDP Number               : 
     Monument Description     : 20 cm diameter stainless steel cylinder
       Height of the Monument : 1.30 (m)
       Monument Foundation    : Exposed bedrock
       Foundation Depth       : 4.00 (m)
     Marker Description       : welded plate with a centered 5/8th inch bolt
     Date Installed           : 2009-07-02T19:00Z
     Geologic Characteristic  : Bedrock
       Bedrock Type           : Sedimentary
       Bedrock Condition      : Weathered
