Nodule and Pottery Foundation fill, HR Area 21

Some of the later houses in HR area were constructed on top of massive deposits of garbage consisting of brick rubble, broken pottery and sometimes a thin layer of crushed, vitrified terracotta nodules. Three sequences of rebuilding can be seen with different basal levels of each wall. The additional wall segments were not bonded with the earlier walls to the right. Different techniques of brick bonding are also seen in each wall.
