Comet Airburst Could Have Caused Pre-Columbian Native American Civilisation To Decline, Study Says

The Hopewell culture (aka Hopewell tradition) is a people indigenous to the east-central part of North America from 200 BC to 500 CE, before the arrival of Christopher Columbus. Scientists don’t know what they called themselves but the name Hopewell comes from landowner Mordecai Hopewell, on whose property mounds they built were discovered.
