Rakhigarhi in Haryana is one of the largest such sites

Excavations have begun at the two Harappan sites of Binjor in Rajasthan, close to the India-Pakistan border, and Rakhigarhi in Haryana.
While the Archaeological Survey of India’s Excavation Branch at Purana Quila, New Delhi, is excavating Binjor, the Deccan College Post-Graduate & Research Institute, Pune, and the Haryana Department of Archaeology is excavating the Rakhigarhi site, 25 km from Jind. About 350 km separate Binjor from Rakhigarhi. As the crow flies, Binjor is situated seven km from the border, in Anupgarh tehsil of Sri Ganganganar district.
There are about 2,000 Harappan sites in India, Pakistan and Afghanistan, with 500 in India and 1,500 in Pakistan.
At its glory, the Harappan civilisation flourished over two million square km, from Sutkajendor on the Makran coast of Balochistan to Alamgirpur in Uttar Pradesh, and from Manda in Jammu to Daimabad in Ahmednagar district of Maharashtra.
Sanjay Manjul, Director, Institute of Archaeology, New Delhi, who is director of the excavation at Binjor, said the excavation was being jointly done by the ASI’s Excavation Branch at Purana Quila and the Institute of Archaeology.
Vasant Shinde, Vice-Chancellor, Deccan College, is the director of the excavation at Rakhigarhi. Professor Shinde said that with the discovery of two more mounds last year at Rakhigarhi, the site had staked claim to be the largest Harappan site.
One of the two newly discovered mounds would be dug this season.
