Collinsville Illinois USA Woodhenge Dial 94
At the Cahokia Mounds is a woodhenge discovered in the early 1960's during excavations and has been reconstructed. There are a series of wood posts in multiple circles that indicate various solar events such as the solstices, equinoxes, and what are thought to be special festival days related to the agricultural cycle of the region. Critical posts also align with the mounds of the site on certain dates. The outer of 3 circles of posts has a diameter of 410 feet with 48 equidistant posts. Each post is about 20 feet high. Equinox and solstice sunrise observations are held at the site on the Sunday morning closest to the event.
