Over a century ago Theobald (1860) described the Pleistocene deposits of the middle reaches of the Narmada river and noted the presence of Pleistocene fauna and man-made tools of stone. Eighty years later the Yale-Cambridge expedition in 1935 carried out the first systematic work under the leadership of De Terra and Paterson (1939) whose major concern was with deposits of the glacial and peri-glacial zones. But their brief survey of the Pleistocene deposits of central and southern India was very valuable, even though their extension of glacial chronology to the sub-tropical zone was mainly based on lithic-tool typology. Since 1947 considerable prehistoric research has been carried out in Peninsular India but without much success in establishing Pleistocene chronology on firm grounds. During the last decade a number of observations and researches have been carried out by several workers in the Narmada valley (Joshi, 1958, Subbarao, 1958, Malik, 1959a, Sen, 1961, Khatri, 1961, 1962, and Sankalia, 1963).The present project carried out jointly by the authors was primarily concerned, not with collecting stone tools, but with understanding the stratigraphy and chronology of Peninsular India.
