Wow! Great info and it may explain what I spotted recently in Portland, ME. I was at the Portland Head Lighthouse and spotted two Benchmarks, labeled National Ocean Survey. I attempted to log them on Geocaching.Com but there's no PID associated with these two marks. The ID on them ends with A for one and B for the other. I looked around and did not see either a "C" or another Benchmark. A and B are only a very short distance apart. Does this jive NGS Surveyor?
