Yet in the last decade of the previous century the Masurian Lake District appeared as an area almost completely void of pottery in the Iwno-Trzciniec style (DĄBROWSKI 1997: 14-19; CZEBRESZUK 2004; MANASTERSKI 2009: 16 sq.). Research of the last 20 years has brought discoveries of several settlement sites in this area, which were dated to the end ofthe Neolithic and the beginning of the Bronze Age. These sites yielded very rich sources, among which pottery is the most numerous (MANASTERSKI 2009: 32 sq.). The most significant sites are Ząbie, Site X, the Olsztynek Commune, and Szestno, Site 2, the Mrągowo Commune (MANASTERSKI 2009: 21-30). Among syncretic materials with features of Para- -Neolithic (the Neman Culture, the Linin Group), Late Neolithic (the Globular Amphora Culture, the Corded Ware Culture) and Early Bronze Age cultures (the Proto- and the Mierzanowice Cultures, the Iwno Culture and the Trzciniec Cultural Circle), the most numerous are these with a clear presence of the Iwno-Trzciniec stylistic component (Figs. 3-8). It clearly points to the participation of the Iwno Culture population in the process of “Iwienisation/Trzcinietisation” of Para-Neolithic groups in this region. Taking the radiocarbon date into consideration (3660±60 BP, 2200-1880 cal BC; GdA-480) which was acquired from Feature 192 at Ząbie, it is possible - in spite of the lack of pottery in this feature - to assume a very early formation of a society with early Trzciniec characteristics in the territory of Masuria.
