Number of Bench marks: 4

Number of Surveys to 1993: 3
Date of Initial Survey: 30 March 1989
Date of Latest Survey: 15 December 1992

Trespass Permission: None needed, although the Bureau of Land Management seems to believe that it should be informed.

Directions: From Indio, take Hwy 86 south to Hwy 78. Turn right, proceed 2.6 miles, and park. Part of the array crosses the road at that point.

Comments: This quadrilateral and leveled alignment array was established to monitor future activity on a northeast-striking fault thought to be connected seismotectonically to the Superstition Hills fault and to the seismo-mechanics of the Salton basin. Bench marks are Class B rod marks driven to refusal and capped with a stainless steel nipple. No significant changes have been observed among the three surveys.
