DESCRIBED BY US GEOLOGICAL SURVEY 1949 5.6 MI W FROM DINUBA. ALONG ROAD TO KINGSBURG, 6 MILES EAST OF KINGSBURG P. O., 33 FT. EAST OF CENTER LINE OF ROAD, 14 FT. SOUTH OF ROAD RUNNING EAST, IN CONCRETE HEAD WALL OVER IRRIGATION DITCH. WITNESS POST SET.
The headwall in the 1949 description has been rebuilt and the irrigation ditch on the west side of the road has been piped underground. It looks as though the entire culvert undercrossing has been moved about 20-30 feet south.
The cardinal ties to the roads put the position in the top of the ditch bank about 15 feet north of the ditch, with no evidence of a concrete headwall. The existing headwall (built with stacked, wet bags of concrete mix) is not a suitable place to mount a benchmark.
