Geo 730: Jan. 13, Day 378: MAPMB Benchmark

The thing that caught my attention with this benchmark, on the southwest abutment of the Mary Adams Peacock Memorial Bridge, was the "Reset 1984" note. During the visit, I was puzzled, but my guess was that it had been re-surveyed to check for any tectonic offset- vertical or horizontal, who knows? Turns out, the bridge was "remodeled in 1985," and this benchmark's "reset" is probably associated with that construction.
