Spring is on the way, bringing longer days, warmer weather, and a chance to explore the ancient earthworks at Spiro Mounds Archaeological Center.

On Saturday, March 20, visitors can take part in guided tours that tell the story of one of the country’s most significant prehistoric sites. The tours will be led by Anna Vincent, current director of Spiro Mounds. Two tours will be offered that day — one at 11 a.m. and another at 6 p.m. The 6 p.m. walk will conclude with a sunset viewing on the upper terrace.

In the event of inclement weather, talks will be given inside the visitor center. Participants will learn about this unique prehistoric mound site, including the different types of mounds, their purposes, the significance of the solstices, and the solar alignments that occur at Spiro. Vincent will share the history of excavations at the site, discuss Native ceremonies and stories, recount unusual events associated with the mounds, and answer visitors’ questions.

The tours are included with the standard cost of admission to the site. View a complete list of admission fees at Spiro Mounds Archaeological Center.
