Plum Bayou Mounds Archeological State Park
Plum Bayou Mounds Archeological State Park, Archaeological state park in Lonoke County, Arkansas.
Located on the banks of Mound Lake, the park contains three preserved mounds from an original complex of eighteen prehistoric ceremonial structures.
The site was first documented by French explorer Louis Bringier in 1812, leading to subsequent archaeological investigations by the Smithsonian Institution in the 1870s.
The mounds were constructed between 700 and 1050 AD by the Plum Bayou people according to specific alignments with solar positions and standardized measurements.
The park features a visitor center with interpretive exhibits, an audiovisual room, and two trails totaling 2.35 miles for exploring the archaeological site.
The site includes what were originally 49-foot and 38-foot platform mounds, making them the tallest surviving Native American mounds in the state of Arkansas.
