I have a Geodetic Control File on my Google Earth. I noticed this "was on the way" to a new cache within the park and just had to find it. It is marked by a single metal fencing stake. We had to chop the grasses away with our walking sticks to reveal the Benchmark.
From the Data Sheet: "Description: DESCRIBED BY OCS 2003 - FOUND 3 3\4" OCS ALUMINUM BENCHMARK DISK STAMPED "3AA-12-70", SET IN THE TOP OF A 6 IN. BY 6 IN. CONCRETE POST.
