Comments:
The Grant Boundary Road nail array replaces an earlier nail line established
12 June 1968 by Bob Burford. It trends 022°, and the San Andreas fault
strikes 142° at this site. A deep sag in the street here precludes
measurement of the nails with a kite string. The street was resurfaced 3
January 1989, obliterating Burford's line. The new nail line was established
on 28 January 1992 and last measured on 10 April 1993.
