No, not that one.
This Stonehenge is atop a bluff on the Washington side of the Columbia River near Maryville. It was built between 1918 and 1929 by pacifist-entrepreneur Sam Hill as the first monument to World War I soldiers. Mr. Hill mistakenly believed that the original Stonehenge was the site of human sacrifice, and the monument was intended to remind viewers that people are still sacrificed to the god of war.
The monument is dimensionally accurate, but because it is at different latitude, longitude and altitude, and is is misaligned from the original by 3 degrees, it cannot function as a calendar. It is not made of stone, but rather reinforced concrete.
Stonehenge is part of the Maryhill Museum of Art, also founded by Sam Hill.
