Overview
Spiro Mounds is one of the most significant prehistoric sites in North America and the westernmost major Mississippian ceremonial center, occupied from approximately 850 to 1450 CE. The Craig Mound at Spiro contained one of the largest caches of ceremonial objects ever found at a pre-Columbian site.
Historical significance
Spiro was a major political and religious center of the Caddoan Mississippian culture and an important node in the extensive Southeastern Ceremonial Complex trade network. The looting of the Craig Mound in the 1930s represents one of the most significant losses of pre-Columbian archaeological material in North American history.
Key discoveries
- The Great Mortuary inside Craig Mound — a hollow log tomb containing thousands of ceremonial objects
- Shell gorgets and cups engraved with Southeastern Ceremonial Complex iconography
- Copper repoussé plates depicting warriors, falcons, and supernatural beings
- Wooden litter poles and cedar poles — among the rarest surviving wooden artifacts from the Mississippi Valley
- Effigy pipes, conch shells from the Gulf, and whelk shell beads indicating broad trade networks
About the site
Spiro Mounds Archaeological Center preserves 11 prehistoric mounds on a low ridge above the Arkansas River in eastern Oklahoma. The site was occupied primarily by the Caddoan Mississippian culture from approximately 850 to 1450 CE, serving as a major ceremonial, political, and trade center for a region extending from the southern Plains to the Gulf Coast.
The site's largest mound, Craig Mound, was the location of an extraordinary discovery that also precipitated the site's greatest loss. In the 1930s, commercial diggers leased the land containing Craig Mound and extracted thousands of objects from a large hollow chamber — the Great Mortuary — inside the mound. The artifacts, including engraved shell cups, copper repoussé plates, effigy pipes, textiles, and wooden objects, were sold to dealers and collectors around the world before systematic archaeological investigation could occur.
The looting of Craig Mound prompted Oklahoma to pass the first state law protecting archaeological sites in the United States in 1935. Subsequent professional excavations by the University of Oklahoma recovered additional materials and documented the mound's stratigraphy.
The surviving artifacts from Spiro are among the finest examples of Southeastern Ceremonial Complex — also called Southern Cult — iconography, a pan-regional artistic tradition depicting warriors, falcons, serpents, and supernatural figures. Spiro was connected to Cahokia and other Mississippian centers through an exchange network that circulated prestige objects, religious iconography, and elite practices across the Southeast and beyond.
