The stone jar sites of the North Cachar Hills, Assam, Northeast India have been a subject of great interest since their first discovery in 1929 by James Philip Mills and John Henry Hutton. In Southeast Asia, they were first reported by McCarthy (1900) in Laos and subsequently by the French archaeologist Madeleine Colani in 1935, who recorded them in great numbers, and speculated about their connections to Assam within a wider salt trade network. The present paper focuses on the discovery and documentation in February 2020 of seven previously unreported stone jar sites from Northeast India along the Saipung Subdivision of the East Jaintia Hills in Meghalaya State. These stone jars form the extreme most westerly extension of the stone jar culture reported from Northeast India. A small-scale excavation of four jars, and radiocarbon dating of East Jaintia Hills stone jars have helped to provide key new insights into cultural and mortuary practices of the stone jar people of this region. The archaeological evidence indicates that the stone jars are visible relics erected on top pits where the post-cremated remains of the dead were buried. The outcomes of this project have significance for our broader understanding of stone jar sites across Northeast India and Southeast Asia.
