1. Site Identification of the GPS monument

        Site Name              : College Geophysical Observatory
        4 char ID              : CLGO
        Monument Inscription   : (none)
        IERS DOMES Number      : TBD
        CDP Number             :
        Date                   : 11 March 1996
        Additional information : Antenna mounted above pillar on threaded
                                 brass rod. Below the threads, the brass
                                 rod is 5 cm diameter. The vertical reference
                                 point is the top of the thick section of the
