Feature 141 is an oblong basin in the southwestern quadrant of the Miami Circle. The walls are uniform, with a slight taper at the eastern and western sides and with almost vertical walls along the long axis of the feature. Evidence of vertical cut marks was noted by the excavators. Three smaller holes occur in the base of the feature. Excavation of the midden produced animal bone, some marine shell, a small collection of pottery, as well as two piles of limestone cobbles.
