+happycycler Posted June 11, 2003 Share Posted June 11, 2003 Yes. This past weekend I found a benchmark (PU 07, 2001 -- too new for the GeoCaching database) that had a cross made of white plastic sheets with the benchmark in the center of the cross. The plastic was getting worn out but I could tell where it had been. It was in a growing and active area near I-44 in Missouri. Quote Link to comment
