Folks, A long time ago I worked for a division of Litton Industries. One day we visited the Litton Guidance and Control Systems Division, which manufactured Optical Gyros. Part of the test facility was a granite slab mounted using isolators on a column in a hole. I was told that the column went down to bedrock to minimize vibration.
