is generally believed that upper-class members of society would live on the highest mounds, while lower-class members inhabited smaller living spaces.) The State of Indiana constructed a modern stairway ascending the mound to protect it from erosion of pedestrian traffic. Archeological evidence suggests there may have been a log stairway in prehistoric times. Mound F (Temple Mound) Mound F, the only mound that is completed excavated, was a platform mound measuring by and in height. Excavations showed that the mound was built in several construction phases with different occupation episodes on the different levels. The episodes of occupation include a structure at the original ground layer, followed by another structure on what is known as "occupational layer 2". This was then covered by the "inner mound surface", a layer of mound fill and more structures. The structures on this level seemed to have been domestic in nature. The next layer of mound fill is known as the "primary mound surface" and was surmounted by a large rectangular structure with at least two rooms and anterooms, or porticoes, appended to it. The final layer of mound fill is the "secondary mound surface". Due to the amount of historic period soil disturbance on the summit it is unclear if any structures sat atop this phase. Mound F was destroyed during the process of its excavation and subsequently re-constructed to show its original appearance. The reconstruction features a temple structure surrounded by a palisade and stairs leading to the summit. Mound E Mound E, the third largest mound, measures by . Its upper platform is by . Because this earthen mound was never cultivated, it is considered to be the site's best example of a truncate mound. Palisade Archaeological excavation revealed a set of two palisade (stockade) walls. The outer palisade surrounded the perimeter of the town with the Ohio River acting as a barrier on the south side. An inner palisade bisected the interior of the site. An entrance to the town was believed to have been on southwest corner of the palisade, based on archaeological findings at that location. Parallel to the stockade walls, another barrier (similar to a picket fence) was set outside the stockade. It was designed to slow attackers as they came into range. A reconstruction of part of the stockade, based on archeological evidence, was made in 1972. The reconstructed walls are high and have wooden posts
