Spiro Mounds, located in Southeastern Oklahoma is one of the most important prehistoric Native American sites in the United States. It is the western-most outpost of a great Caddoan empire that stretched throughout the Mississippian River Valley.
Today, Spiro Mounds remains an archaeological hotspot, as well as a fascinating tourist destination point. Manicured trails take visitors throughout the park, while an interpretive center helps provide more history behind Spiro Mounds.
