Summit Benchmark

 

 

Benchmark found at summit of Big Kennesaw Reference mark 1 Reference mark 2

 

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:
 

"Kenesaw (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."
