although i've never seen stonehenge in person,
your description sent chills up my spine.
Descendent Of Stone Age Skeleton Found (Cheddar Man - 9,000 Years Old)
"British scientists Saturday celebrated their feat of tracing a living descendant of a 9,000-year-old skeleton and establishing the world's oldest known family tree. "
My visit left an entirely different impression than that experienced by U.P. There is something mystical about the place, I agree. But for me it was more a "connectedness" with a very long stream of human experience. I loved it and would go back at any opportunity, just to experience that feeling again.
My visit included other nearby mystical places: Avebury, very much the equal of Stonehenge in its own way; Woodhenge, Silbury Hill, etc. Those places are all within direct line-of-sight with each other, and at the time I visited I realized this part of the Salisbury Plain must have had particular significance to the builders of all those monuments and others nearby.
