The Midwest’s Hidden Geography: Ancient Seas, Lost Cities & Craters
The Midwest is more than cornfields, cows, and flat highways. Beneath its quiet scenery lies a landscape shaped by vanished oceans, ancient rifts, buried rivers, lost cities, and an asteroid crater hidden under Iowa farmland.
Explore the ancient rift where North America once began to split apart, the earthquakes that made the Mississippi River flow backward, and the buried Manson crater in Iowa. Discover the lost city of Cahokia, the ancient sea that covered Kansas, and the Driftless Area that escaped glaciation.
The journey also reveals vanished Lake Agassiz, Nebraska’s vast Sandhills, and a dark matter laboratory deep beneath South Dakota. These hidden features tell a surprising story of Midwest geography, geology, and human history.
The Midwest isn’t a place where nothing happened. It’s a place where extraordinary events left traces that are easy to overlook.
