Cross-sections inside (top) and outside (bottom) of perimeter wall [250]. The wall itself, being of mud-brick, was heavily eroded, sometimes to a lower elevation than the adjoining more densely packed street debris. As can be seen in the bottom cross-section, the debris outside of curtain wall [296] was deposited later than the bricks and debris dumped between that wall and the perimeter wall. The absence of pointed-base goblets (73) from all except the uppermost debris deposits indicate that the lower debris levels date prior to Period 3C at Harappa, probably to the second half of Period 3B.
