Miami Circle - Virtual Tour, Location 6A
Feature 18 is a somewhat irregular, rectangular basin located at the western edge of the Miami Circle feature. Five smaller holes are carved into the bottom and southern margin of this feature. Vertical cut marks were noted on the basin walls. Excavation of the midden deposits within the basin produced shell, perforated shark teeth, marine shells, as well as a large limestone boulder that may have been used to wedge posts into the smaller holes.
