Concentrations 2–6 were located at the top of a hamra layer (Netanya hamra) that was partly covered with sand dunes and vegetation. The artifact density in the concentrations was low and no relation between their location and archaeological sites was evinced. Approximately a thousand flint artifacts from the Epi-palaeolithic period were gathered, representing all the stone- knapping phases from cores to finished tools. All the artifacts were covered with patina, ranging in color from yellow to white, which is characteristic of many sites from the Epi-palaeolithic period in the coastal plain. The collected artifacts included 37 tools, 31 cores, 474 waste flakes and several hundred chips of various sizes. Noteworthy among the tools are the scrapers on retouched flakes and blades (Fig. 2:1–3), retouched bladelets (Fig. 2:4–7) and diagonally truncated backed bladelets (Kabaran points; Fig. 2:8, 9). Most of the cores are pyramidal bladelet cores that have one striking platform. The most common elements in the debitage are the flakes (314), whereas the number of blades, bladelets and core debitage is considerably lower.
It seems that the concentrations of flint artifacts were partial remains of sites, which were destroyed due to dune movement and erosion, as well as development work and construction. The multitude of retouched bladelets that are non-geometric (38%) and especially the Kabaran points (11%) indicates that the assemblage belonged to the Kabaran culture (18,000–15,000 BCE.). A similar proportion of tool ratio is known from other sites in the region that belong to the Kabaran culture, among them Nahal Hadera V, Hefzibah, Umm Khaled and Poleg 18X.
