A small fraction of Harappa has actually been excavated. Most of the site is untouched by the archaeologists tools. It may be that future non-invasive techniques like ground penetrating radar help us map out what remains under the soil.
In the distance, the modern town of Harappa survives on another set of mounds. During ancient times they were separated from Mound AB in the foreground by a river channel.
These giant ringstones are similar to ones found in Mohenjo-daro and Dholavira. Local legend claims they were the rings of a giant 17th century saint (Baba Nur Shah) who is buried on Mound AB.
The mounds at Harappa remain largely unexcavated. Approximately half a percentage of the site's area was unearthed each season by the Harappa Archaeological Research Project (HARP) in the 1990s.
