AHMEDABAD, INDIA—A 5,000-year-old stepwell has been discovered in Dholavira, one of the largest known cities of the Indus Valley civilization. Scientists from the Archaeological Survey of India and IIT-Gandhinagar say that the well is almost three times bigger than the Great Bath at Mohenjo Daro. They will use 3-D laser scanners, remote-sensing technology, and ground-penetrating radar to analyze Dholavira’s ancient water system. “Various surveys have indicated other reservoirs and stepwells may be buried in Dholavira. We also suspect a huge lake and an ancient shoreline are buried in the archaeological site,” V.N. Prabhakar of IIT Gandhinagar told The Times of India.
