Castine Indian Mounds

Monks Mound

The Castine Mounds in Illinois, particularly Monk Mound, are immense earthen structures revealing human craftsmanship rather than natural formations. Monk Mound, nearly 100 feet high and 600 yards in circumference, features a broad terrace and has yielded artifacts like pottery and corn, indicating its artificial origin. Various purposes for the mounds are suggested, including cemeteries and religious sites. These ancient structures invite speculation about the cultures that built them, much like the enduring mysteries of the pyramids of Egypt.

Cahokia Mound

The ancient civilization at Cahokia took advantage of the nearby waterways and the rich soil to sustain life in the American Bottom.

Cahokia Mound, located in Madison County, Illinois, is the largest prehistoric earthwork in the United States, situated in the fertile American Bottom region near St. Louis. Originally surrounded by a group of at least 45 mounds, it is a quadrangular pyramid measuring 998 feet by 721 feet and standing 99 feet tall, covering an area of approximately 16 acres. The mound’s construction involved significant labor, reflecting the ingenuity and organizational skills of the ancient civilizations that inhabited the area.
