The basalt columns are now lowered into position. These will be the six corners of the dry stacked hexagon structure. (The granite quoins which were precisely stacked in position, had to be disassembled and neatly stacked to the sides so as not be in the way of maneuvering in the basalt columns.)
The proper measuring of the columns so that the bottoms were cut square was essential. Then each column had to be skilfully rigged with sturdy straps and lifted into place in its proper orientation. These silent sentry columns final placement depended on a crack team of rock stars. Mark R, Sean A and Shawn K. The Gradall operated by Peter M. did the necessary usual amazingly precise lifts.
Sean A complains a lot. Please caption this one.
