Answer: Rajasthan
Notes: Recently, a Harappan site was discovered at Ratadiya Ri Dheri in Jaisalmer district, Rajasthan, marking the first Indus Valley settlement in the Thar Desert region. The site belongs to the mature urban phase of Indus Valley Civilization, dated between 2600 to 1900 BCE. It is a 4,500-year-old rural Harappan settlement located near the India-Pakistan border. The discovery connects earlier Harappan sites in northern Rajasthan and Gujarat, filling a major gap in the archaeological map. It provides evidence of cultural and trade continuity across desert regions of northwest India.
