Mound 72

The ridgetop mound contains multiple burial layers with distinct arrangements, including mass graves and individual interments across its structural components.

Excavations between 1967 and 1971 revealed three smaller mounds beneath the main structure, documenting complex mortuary practices from 1000-1200 CE.

The burial arrangements within Mound 72 indicate a structured social hierarchy, demonstrated by different treatment levels from sacrificial victims to elite members.

The mound aligns with the winter solstice sunrise and summer solstice sunset, providing visitors insights into ancient Native American astronomical knowledge.

Researchers discovered a notable burial containing a male positioned on a bird-shaped arrangement made from 20,000 marine shell beads.
