[3] The site is considered as a possible candidate for the Province of Anilco encountered by the Hernando de Soto Entrada in 1540.

[5][6] The site is also considered to be the location of the protohistoric Quapaw village of Osotouy (or Ossoteoue) first encountered by French explorers in the late 17th century.

The excavations included burials, with graves in extended, flexed, and secondary interments scattered throughout the site and oriented in many different directions.

The most unusual formation at the site is Mound A, which is conical in shape, and was built in two stages.

Ceramics found at the site are consistent with native occupation at the time Henri de Tonti established the first French outpost west of the Mississippi at the Arkansas Post in 1686.
