Cahokia Mounds State Historic Site Interpretive Center holds a great collection of artifacts. Bottom left, arrow and spear points and potsherd - William Clark mentions finding such items among mounds while exploring near the camp on Wood River. A mural in the center depicts Monks Mound as it may have been at the height of Cahokia's habitation. This largest of North American prehistoric earth structures rises 100 feet above the ancient plaza. A large building on the top housed the chief and was the seat of government and center of ceremonies. The view southwest from the top shows downtown St Louis and Gateway Arch.
