Head for Cahokia Mounds

  • Modern-day mounds stand as mute testament to the societies that preceded us along the Mississippi River.

The Metro East, like the rest of Illinois, is a mostly vast expanse of flat, swampy prairie, but about a thousand years ago, a little-understood native culture built massive earthen mounds that now exist as evidence of a complex and densely populated city — which at its height included rings of "suburb" dwellings that extended across the river to the areas of present-day St. Louis.

Today, the Cahokia Mounds State Historic Site (30 Ramey Street, Collinsville, IL) is spread out over three-and-a-half miles of crisp green grassland — and is dominated by the 100-foot-tall Monks Mound. Taking the stairs to the top platform, the view extends for miles.

However, before attempting to surmount the mound, visitors should head to the interpretive center — which is different than a museum, notes archeologist and the center's executive director Lori Belknap.

"Our goal is that the visitors would leave with an understanding of the life of the people who lived here a thousand years ago," she explains. "That interpretation given to visitors is grounded in science. Everything we are telling you are things that we have learned through excavations, and we keep it very close to the actual data we recovered in early digs."

Along with hundreds of excavated artifacts, the center's exhibits illustrate the remarkably urban existence of the nearly 20,000 residents believed to have lived, worked and died in Cahokia at its height around the year 1200 A.D.

Though they left behind no writing, the Cahokians did leave structural demonstrations of their knowledge, including "Woodhenge," a solar calendar of wooden posts that's been functionally rebuilt on the site. Every year, on solstice and equinox, crowds gather in the ancient circle to watch the sunrise.

That the center is dedicated to interpretation, not just preservation, also hints at the mystery of the fate of the Native American culture that thrived here. Only a tiny part of the total area has been excavated, and researchers have spent years looking at the possibilities presented by the evidence they uncover. The Interpretive Center lays out these threads with lushly illustrated maps and models, as the galleries and exhibits tell the story of the end of a powerful civilization, one that had once been part of a continent-spanning trade network and religious system that was already centuries gone by the time the first Europeans arrived.

The Cahokia represents the largest settlement of "Mississippian" culture, which in Southern Illinois grew to a population of tens of thousands by maintaining huge agricultural operations. Today, the people are gone, but the impact of their lives and work remains. Belknap argues that it's important that the current residents recognize the depth of history in the land around them.

"Our site dominated that area at the time," Belknap says. "It went into East St. Louis and across the river. It was a very large civilization here, and it's important for people to understand that."

She says the center hopes that easing pandemic restrictions in the coming months will allow the site to schedule its usual array of kids and archeology events for the year. In the meantime, the walking and hiking paths remain open, covering sixteen total miles in a loop through the peaceful, mound-punctuated landscape. The Interpretive Center is open to the public, though visitors are asked to RSVP at 618-346-5160 so the center can maintain an occupancy limit and social distancing.
