In 1998 some friends of mine started a community garden at another friend's house not to far from me. I saw this as an opportunity to do something I'd always wanted to do, stand some really big stones on their end. My wife and I had recently watched a show on PBS about the stones at Stonehenge and the great obelisk at Alexandria, with two groups putting their theories to practice and I thought "we could do that". So I spoke with a friend who was a rigger for a local power company, and another who was a geological engineer. We decided we could do it, but we wanted to erect the stones with no modern equipment.
A year later we erected the uprights (14 tons of columnar basalt), and 15 months after that we placed the lintel, (3.5 tons of granite). All this was done with ropes and simple pulleys, and a LOT of volunteers pulling on the ropes!
Over the next decade we added smaller stones around to make a circle
It was one hell of an experience which none of us will ever forget.
