Serpent Mound - Ohio Serpent Mound - OhioCredit: dreamstime. The figure of a giant snake, apparently uncoiling itself, was excavated in the late 19th century. The massive serpent is nearly a quarter-mile long. Recent carbon-dating research suggests the Fort Ancient culture built the monument roughly 900 years ago. The serpent's body is made of raised berms of grassy earth that weave across a plateau. On the summer solstice, the setting sun aligns with the snake's head.
Stonehendge England.... Meaning of Solstice 'Solstice' (Latin: 'solstitium') means 'sun-stopping'. The point on the horizon where the sun appears to rise and set, stops and reverses direction after this day. On the solstice, the sun does not rise precisely in the east, but rises to the north of east and sets to the north of west, meaning it's visible in the sky for a longer period of time.
