HARP (Harappa Archaeological Research Project) a group of scholars from a variety of fields dedicated to advancing the study of the ancient Indus Valley civilization.
The cross section of the Ravi phase pit shows multiple episodes of filling and plastering. The contents were collected for flotation, which recovered seeds of barley and wheat as well as some charred wood.
Each Ravi phase stratigraphic layer was identified and excavated, and the many rodent holes, obvious both in the exposed area and in the section, were isolated. Here delicate trowel work has revealed the circular outlines of the top of a storage pit.
Ravi phase houses seem to have been constructed with wooden supports and walls made of plastered reeds. A lump of plaster with reed impressions is seen in this image.
Ravi phase hand-formed (not in molds) mud-bricks were found in the early levels mixed with ash and broken pieces of pottery. They may originally have been part of a firing structure or kiln.
