        Note                   : SIO2 was built as a reference mark for SIO1, and
                                 for the first 2 years was used for survey ties
                                 and various receiver/antenna tests. When SIO1
                                 was destroyed (June 1992) due to construction
                                 of new IGPP building, SIO2 became the primary Scripps
                                 site. SIO3, the new PGGA monument at Scripps,
                                 replaces SIO2 as the primary Scripps PGGA site.
