What is the Stonehenge built from and where did it come from?
The Missouri S&T-Stonehenge is made of granite which was quarried in Elberton, Georgia. The rock is a hard igneous stone, which is commonly used for monuments. Elberton, Georgia is a major center of the American Granite Quarrying industry. This happened partially because, in 1978, the National Science Foundation funded a study to find better ways of quarrying granite in the United States. One of the ways that were tested was through the use of high pressure waterjets and Dr. Summers of the Missouri S&T RMERC was one of the panelists who worked on that program. It is interesting to note that one of the quarries in which the original testing of waterjetting was carried out in 1978, later served as the source rock for the granite which forms the Missouri S&T Stonehenge. The work was subcontracted from the Elberton Granite Association to Georgia Institute of Technology. Missouri S&T carried out a field demonstration for this consortium during the week of November 27, 1978. Cutting rates of
