A 1-1/4 inch diameter steel rod(point P1 -see Point Table)was found 1.7 feet <br /> below the surface, under a water box lid-1 feet below the surface,the same as found 16 <br /> by Sandsnes in 2004. I accepted this as the section corner position. All 4 witness ties rut-, . =s <br /> per Sandsnes 2004 record (P2-P5)were found in the same location. V '%\:\/. <br /> 2.
