| Auxiliary benchmarks | BMR 8290 3092 NMV/C/443: small piece of blue metal gravel embedded in and protruding slightly above the concrete top of the sea wall. NMV/C/444 & NMV/C/445: centres of triangles carved in flat concrete on the top of the sea wall of the jetty, with their numbers next to them. TRIG 'M': drill hole in a damaged concrete block. |
