4,000 years old?
Alexandria, Va. — This is Tim, your roving reporter. Did you know that America has its Stonehenge? I know because I went there with my brother and grandparents. It's in North Salem, New Hampshire. It used to be called Mystery Hill. The mystery is they do not know when it was built. They do not know how it was built, or who built it.
Radiocarbon tests show the scientists that it is 4,000 years old.
The people had no calendar. They made a stone calendar. It only worked when there was a sunrise and sunset. It was and still can be used in telling solar and lunar events of the year, equinoxes and solstices.
We explored stone chambers and tunnels and caves. There was a sacrificial table with an oracle chamber behind it, and there was a watch house.
I hope the mystery is solved one day.
