Plum Bayou (650–1050 CE) had an incredible trade reach before Spiro's mounds even rose! 🦉 They got shell ornaments from the Gulf, precious gems from the Ozarks, and copper from the Great Lakes — even connecting with effigy mound builders in Michigan and Wisconsin. Excavated mounds revealed layers of feasting debris, mostly deer bones. This suggests leaders hosted big community feasts as reciprocal gestures, a practice seen in later documented Mississippian groups. Their art is surprisingly sparse though — just a tiny owl effigy and shell jewelry.
