The earliest settlement, during Period 1 (c. 3300-2800 BC), was on the west side of Mound AB and NW corner of Mound E. During Period 2 (c. 2800-2600 BC) all of Mounds AB and E came to be occupied, and by the end of Period 3 (c. 2600-1900 BC), the Harappan Period, most of the area covered by the plan was in use. During Periods 4 and 5 (c. 1900-1300 BC) there was a retraction of settlement to the areas of Mound AB, modern Harappa Town, and the NW corner of Mound E. This plan also shows the location of the 2000/2001 excavation areas.
