"Stonehenge" in America?

Do We Have our very own Stonehenge right here in the United States?
And, could it have been built by the same people as Stonehenge in England?

America's Stonehenge is a Prehistoric Site in Salem, New Hampshire.
The Owner of the Ancient site claims it dates back some 4000 years.
It appears to be in Solar alignment. Just like at Stonehenge someone placed standing stones in a circle, where the placement is key.

When viewed from the center of the site each standing stone aligns with the sun, on important days of the year, such as the solstices. Equinoxes and Cross quarter days are even aligned.
