Poop Happens, and 10 miles outside of modern day St. Louis, Missouri in 1150 A.D. a lot of it happened – and then it didn’t. The ancient city of Cahokia was the largest pre-Columbian settlement north of Mexico with a population larger than London. However, within 100 years it was abandoned and remained a mystery until climate scientists and archeologists worked together to study the sediment to find out the secrets within the poop (You could call them The Poop Whisperers).
The findings varied, but the basic understanding that came from the research is that the initial sediment area has higher poop molecule levels and then less and less meaning overtime there was less rainfall. (More rainfall would have caused more washout, burying the molecules further.) Less rainfall is an indication of climate change and also give clues into what likely drove the people of Cahokia out – the inability to continue crop prosperity. Some people say you can tell a lot about people by their shoes, but the same goes for their poop.
