Comments: This quadrilateral is an NGS Earth Movement Study site. Previous NGS surveys are leveling surveys. Bench marks were established in 1969 and are standard NGS bronze tablets. Bench marks A and B were not found in 1989. The NGS determined bench marks heig hts by precise leveling. UCSB determined heights with a Wild TC2000 total station distance meter in 1989. Heights differ between the two agencies between 5 and 10 cm, probably because of the inaccuracy of determining heights by trigonometric leveling.
