Nowa Biała 1 is a unique site of the Federmesser culture in the area of Carpathian Mountains, and also one of the few Final Palaeolithic sites known from this territory. From taxonomic point of view the artefacts represent the Federmesser culture as an element of Arch-backed points technocomplex (APT) – well known from the European Plain and practically quite unknown from the mountains till now. Hunters’ camp, with the dwelling structure and workshop, was situated on a terrace of the Białka River close to its gorge, and in the proximity of a rocky hill (the Obłazowa Rock) – which itself was a great observation spot. The cultural layer found in the site was connected with an initial soil, the presence of which was observed within the aeolian loess-like deposits. Thie age of pedogenic processes (based on OSL dating) was undoubtedly younger than 14.7 ka and older than 11 ka. Radiocarbon dating suggests the Late Allerød age of the site. The present paper contains the results of fieldwork as well as geological and palaeobotanical analyses, provided data on the natural environment at the time when prehistoric hunters settled and also in the preceding period. According to study results, in the Late Glacial, during the time of this settlement in the vicinity of the Białka River gorge the patches of coniferous forests grew, in the valley habitats – alder and willow, and mires formed in the wetlands, rocky hills were covered with open plant communities with steppe and tundra elements. Variability of surrounding environs resulted in diversity of animal species and allowed Final Palaeolithic people to explore differentiated geoecosystems. Access to water and possibility of fishing was provided by the proximity of the river.
