Near Collinsville, Illinois, lie the remnants of Cahokia, the largest pre-Columbian city north of Mexico. Around 1200 AD, it was larger than contemporary London, with massive earthen mounds, the grandest being Monks Mound, dominating the landscape. Yet, this thriving metropolis was mysteriously abandoned by 1350 AD. Standing atop Monks Mound, overlooking the flat plains where a bustling city once stood, one can't help but feel an eerie sense of loss and wonder about the complex society that vanished, leaving behind only these silent, grassy monuments and unanswered questions.
