William F. Romain, of The Ancient Earthworks Project Blog, has written an exciting post about how the Hopewell Mound Group's recently discovered Woodhenge is aligned to the Solstice.
"The interesting thing about the Great Circle design is that the summer solstice alignment is orthogonal to the diagonal of the 1/4 HMU square; and further, the diagonal of the square and its solstice orthogonal establish the locations for at least two of the gateways into the circle. In this design, astronomic observations, geometry, and a specific unit of length are integrated in a sophisticated and unique way. "
