Latitude: N 33°06'18"
Longitude: W 115°50'24"
Length: 422.4m
Number of Bench marks: 12
Number of Surveys to 2000: 6
Date of Latest Survey: 12 November 1994
Date of Initial Survey: 30 March 1989
Trespass Permission: None required.
Directions:
From Westmorland, proceed WNW 14.5 miles on Hwy 86 to Kane Spring. Take old
Kane Spring Road (Jeep Trail) west-southwest about 0.25 mile. Array straddles
the dirt road.
Comments:
This short line is part of a quadrilateral that 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 (Hudnut et a l., 1989).
Results:
Three levelings are compared in an accompanying diagram. The height changes
of the bench marks vary insignficantly among three levelings in three years,
although the behavior of the two bench marks at the southeast end of the
line s uggest that an active, undetected fault strand may exist between bench
marks KS11 and KS12.
