The final field campaign at Uzun Mera was focused on the northern periphery of the northern sector, where trench 10 was excavated. From the observations on the site so far, it is clear that the layers containing the lithic artefacts were deposited by a low energy element at some point during the Late Pleistocene. The sedimentation happened from the North towards the South on the left bank of the Nemanjica stream, thus forming several terraces, of which two mound-shaped elevations are the most prominent. The mound shapes are the result of the aggregation of a mass of cobbles and pebbles of volcanic origin, among which are the materials used for knapping. The excavations of trench 10 revealed that at this proximal point of deposition the larger cobbles are missing, i.e. they were deposited further down towards the end of the colluvium. Instead, the stratigraphy in trench 10 consists of the most dynamic interplay of gravel and sand lenses with clay and silt, almost immediately below the thin (app. 20 cm) plough zone. Also, a pronounced scarcity of lithic artefacts was evident. This was the final piece of the stratigraphic puzzle. Additional samples of sediment for OSL dating were taken from trench 10. Apart from the detailed knowledge of the sedimentation process and the site formation at Uzun Mera, a significant assemblage of approximately 200 lithic artefacts from the Middle Palaeolithic were collected.
The excavation in 2022 at the Uzun Mera site completes a six-year cycle of test-trench investigations of the 1.5km2 territory of surface finds distribution. At the same time, it marks the beginning of a wider international field project and field-school, investigating the Palaeolithic of the Ovche Pole and the Kratovo-Zletovo paleo-volcanic region.
