After four years of excavations at the Uzun Mera Palaeolithic site, the stratigraphic sequences of the two main sectors and their relationship are relatively well understood. The least investigated area is the highest point at the center of the northern sector, an area with a relatively high density of surface finds. Trenches 8 and 9 were placed at this location, not far from one another. As expected, the gravel was also present here. There is an obvious resemblance between trench 10 in the north, and trench 3 and 4 in the south, all having in common that they are positioned at the highest point of the respected sectors. With these excavations there is a clear picture of the layers represented in the vast area of the site. Obviously the two elevations, one south and one north, are the product of the deposition of a mass of sand, clay and cobble stones. This happened during a geological event in the later Pleistocene, most probably involving the near-by stream and the volcanic outcrops not far to the north from the site. The lithic artefacts are associated to these deposits. With time, especially with the intensification of human activities and modern agriculture, those exposed on or near the surface were distributed over the surrounding area and the site reached the current size.
