Remnants of the ancient city of Cahokia, in what’s now southern Illinois

Not far from my grandmother’s house is a ghost city. At Angel Mounds on the Ohio river about eight miles southeast of Evansville, there are a few visible earthworks and a reconstructed wattle-and-daub barrier. There is almost nothing left of the people who build these mounds; in a final insulting erasure, the site is now named after the white settler family who most recently farmed the land.

There are traces of other dead villages along the Ohio and Mississippi rivers, mounds scattered from present-day Indiana to Arkansas and Alabama. In southern Illinois, a few miles from the Missouri border, hidden among empty corn and soy fields, is the center of that dead civilization’s gravity: the lost city of Cahokia.

Cahokia was larger than London, centrally planned, the Manhattan of its day. Most people there would have come from somewhere else. There were defensive foundations, playing fields, and a magnificent temple. There would have been sacred ceremonies and salacious gossip. It must have been a very exciting place to live.

And then, relatively abruptly, it ceased to exist. We know of the city only because of the physical traces left behind. Few stories of Cahokia have survived; it disappeared from oral tradition, as if whatever happened to it is best forgotten. The archaeological record shows traces of the desperation and bloodshed that almost always accompany great upheavals: skeletons with bound hands, pits full of strangled young women.

The North American Drought Atlas, a historical record of climate conditions pieced together from the rings of old trees, provides a hint of what might have happened. The tenth century CE, when the Cahokia civilization would have developed, marked a distinct shift in the regional climate from persistent drought to rainier conditions more suitable for agriculture, centralization, and civilization.

But the good times were not to last…

Some people say “the climate has changed before,” as though that should be reassuring. It’s not: “Lost Cities and Climate Change.”

* “Thanks to the centrifugal pump, places like Nebraska, Kansas, Oklahoma, and Texas had thrown on the garments of fertility for a century, pretending to greenery and growth as they mined glacial water from ten-thousand-year-old aquifers. They’d played dress-up-in-green and pretended it could last forever. They’d pumped up the Ice Age and spread it across the land, and for a while they’d turned their dry lands lush. Cotton, wheat, corn, soybeans — vast green acreages, all because someone could get a pump going. Those places had dreamed of being different from what they were. They’d had aspirations. And then the water ran out, and they fell back, realizing too late that their prosperity was borrowed, and there would be no more coming.”
― Paolo Bacigalupi, The Water Knife (a powerful novel)

As we face facts, we might recall that it was on this date in 1854 that Ticknor & Fields published transcendentalist Henry David Thoreau’s reflection on simple living in natural surroundings, Walden; or, Life in the Woods.
