The five seasons (2015-2019) of the author’s doctoral fieldwork yielded >30 microlithic occurrences in the Sehore and Hoshangabad districts of Madhya Pradesh, central India. The sites were found preserved primarily in the Vindhyan foothills. The targeted survey areas were in the Vindhyas in the north, Gondwanas in the south and in the Narmada floodplains in between. This divides the study area into northern and southern zones within the Narmada basin. These areas yielded a good number of sites in the foothills, forested areas, and a few in agricultural fields. The number of sites in the Vindhyan foothills is greater than those in found in the Gondwana foothills. This uneven distribution of sites in the landscape can lead to various hypotheses, the major factor being the unavailability of preferred raw materials. However, there are a few pockets in the southern group which have yielded primary sites. The distributional pattern of these sites provides a broad overview of hominin mobility across the landscape. This provides an understanding of landscape exploitation by the hunter-gatherer populations, particularly, the selection of locations for manufacturing and utilizing the lithics, finding and acquiring raw materials and for long-term habitation purposes. Most of the sites are found in similar types of sedimentary contexts. However, there can be other reasons for the distributional pattern of the sites including their absence at locations where they were expected. The sites are better preserved in the forested areas along the foothills, partially because of restricted access by the forest department. This paper aims to understand the distributional patterns of the microlithic sites in the study area, prehistoric landscape adaptations, raw material exploitation, site formation processes, and on specific factors that geographically limited the surveys.
