Ancient mounds of RakhiGarhi (Hissar District, Haryana, India)
Rakhigarhi mounds are associated with Harappa Civilization. Many artifacts have been excavated (terracotta objects, beads, burial skletons) from these mounds that establish that Rakhigarhi was an important and large Indus valley civilization site. The following photo (which shows pigeon holes) shows a mound which is yet to be excavated. It shows evidence of a busy settlement as many human made objects are seen jutting out of the soil. When compared to Dhankot mound (district gurgaon), the dhankot mound (photo below with tree roots) does not show buried items as seen in the Rakhigarhi mound. It therefore indicates that Dhankot mound was not, even remotely, settled as extensively as the Rakhigarhi mounds. Dhankot mound photo is being shown here as a sort of 'control', for comparison with the Rakhigarhi mound.
