COLLINSVILLE, Ill. (KMOX) - Curators at Cahokia Mounds State Historic Site have announced that they will mark the annual summer solstice in a manner similar to how Native Americans did a millennium ago.
Woodhenge, a calendar of posts on the site, aligns with sunrise on the longest day of each year, the shortest day, and during the equinoxes, times at which day and night are equal in length. The Mississippian people considered those days sacred, according to experts.
On Sunday, June 21 visitors to the site will be able to stand where residents of Cahokia Mounds once did and watch the sun rise over the mounds.
Curators at the site ask visitors to arrive by 5:20 a.m. for an explanation of Woodhenge by an archaeologist.
