In the SE quadrant of the Circle is an odd mix of natural and artificial features I myself dubbed the “chaotic zone”. Here the deepest sounding on site was a karst-like opening with a slanted wall, the latter containing several small deliberate pits. At the bottom, a “natural window” (fenestration) opened through to an adjoining cavity. The major cavity of this zone is shown at lower left. Just above it is the S end of the backhoe trench scar from construction activities about fifty years ago. If you look closely, you can see the bottom remnant of a basin in the scar at left edge – still containing isolated shell and stone fragments. Large whole and broken shells and columellae of various marine whelks were often found in the basins: here a row of them appears just as they might have when so-laid-out by excavators during actual field work. The sloping bank rises another two or three feet up the unexcavated overburden at top and to right. No sharp profile was maintained here by the Excavators, as the bank was continually collapsed and worn down by people entering and leaving the excavation in this vicinity. The surface appears just as it did in the field: strewn with cans and builders’ trash and rank weeds which grew quickly in the Miami heat.
