From the Parkfield Bridge: Drive southeast on Cholame Road 2.3 miles to Parkfield Cemetary Road. The line begins on Parkfield Cemetary Road ab out 375 m southwest of the intersection; it proceeds up to and northwest along Cholame Road to Turkey Flat Road, thence along Turkey Flat Road across the fault.

This line was established across the San Andreas fault by the U.S. Geological Survey, 2 miles southeast of Parkfield.
Six levelings in nine years are plotted in an accompanying graph. Except for the first bench mark northeast of the San Andreas fault, there is no indication of displacement across the fault nor of nearfield tilt.
