Clearing the ancient Harappan debris from the eroded surface outside of the mud brick city wall at the eastern edge of Mound E. In 1997 this area of Trench 11 was cleared to define the stratigraphic sequence between Period 3B and 3C. It was possible to determine that many of the incised and molded tablets were coming from the second half of Period 3B (c. 2300-2200 BCE) continuing into the beginning of Period 3C (c. 2200-2100 BCE).
