Retaining walls inside perimeter wall 86

Towards the east, in what was probably a low area, a series of radiating mud-brick retaining walls were built to contain rubble that was used as a foundation for later structures, only fragments of which are preserved. In the rubble were found a great deal of charcoal and ash as well as potsherds and fragments of broken terracotta objects and other artifacts. In this image, the dark-colored rubble has been partially removed. Note that North is to the left of the image.
