Monday, Sept. 22-Tuesday, Sept. 23

The end of summer is nigh, and it’s time to look forward to fall’s crop of harvest-themed celebrations. The Spiro Mounds Archaeological Center in LeFlore County continues to mark the change of seasons with an autumnal equinox walk. Walks around the center are at 11 a.m. and at 2 and 7 p.m. Monday, Sept. 22, and Tuesday, Sept. 23. Led by Dennis Peterson, center manager, the walk lasts about two hours, but isn’t strenuous. During the walks, guests will learn more about mounds constructed by American Indian tribes native to the region. They’ll also hear stories and discover the history of the excavation site. Peterson will also share how some of these ancient mounds built through the U.S. line up at sunset on solstice and equinox days. He’ll also share how the mounds were vital to Oklahoma’s earliest peoples, telling them when to plant crops and harvest. Tour admission is $3 for adults and $2 for children.
