The Solar Calendar of the Plum Bayou
Deep in the heart of Arkansas, near the banks of the Arkansas River, stand massive hills of earth that hold secrets from over a thousand years ago. This special place is known today as Toltec Mounds Archeological State Park. Although the name suggests these mounds were built by the Toltec people of Mexico, that is actually a historical mistake made by early settlers. Instead, archaeologistsâscientists who study human history by digging up ancient objectsâhave discovered that a unique group of Native Americans called the Plum Bayou culture built these incredible structures.
The Plum Bayou people lived in the region from about 600 to 1050 CE. Unlike some other ancient cultures, they did not live on the mounds. Instead, this site was a grand ceremonial center. People from nearby villages would travel to this sacred space to gather, trade, and hold special religious ceremonies. To make this gathering place truly spectacular, they built eighteen massive earthen mounds, surrounded by a high earthen wall and a deep ditch.
