While doing some
internet research we ran across some published information
about the locations of these marks
1) "GEODESY -
DESCRIPTIONS OF TRIANGULATION STATIONS IN GEORGIA" is a
booklet produced in 1917 by the Government Printing
Office. The information/description of the benchmark located
on Kennesaw Mountain:
(Cobb County, Ga., F. P. Webber, 1873). About 3 miles
north-west of Marietta on the highest part of Kenesaw
Mountain. The station is marked by a cross and the letters
U. S. C. S. in the top of a granite post 5 inches square,
which projects about 2 inches above the ground. The
underground mark is a cross in a copper bolt set in a drill
hole in the bedrock about 2 feet below the ground. Three
reference marks, each consisting of a copper bolt set in a
drill hole in a rock, are at the following distances from
the station: 2.01 meters (6.6 feet) east, 3.47 meters (11.4
feet) west, and 3.41 meters (11.2 feet) northwest."
