The stone industries of layer 3ust - Kutarey site in North Angara region

There are many archaeological sites located on North Angara region. Although this territory has been investigated since XVIII century, most intensive works are connected with rescue archaeological works on Boguchany hydroelectric power station in 2008-2011. One of the perspective section is Kutarey site (Kutarey River mouth, Senkin (Siniy) Kamen, Ruchei Povarny, Gora Kutarey). This work contains brief analyses of stone industries of Kutarey River Mouth site. The main goal of this work is with a technical and typological analysis to mark the specific of stone industries of layer 3 of Kutarey River Mouth site in the context of new data of this region. The originality of this work consist inthe introducing in scientific turn unpublished collection of stone artifacts of layer 3 of Kutarey River Mouth site, that significantly extend the source base of Neolithic and Bronze age in this region. Kutarey River Mouth site is located on the left bank of Angara river, 15 km lower Kezhma village, on the right bank of Kutarey River. The location was found in 1974 by N.I. Drozdov squad. Hereafter the site was investigated in 2008 and in 2010 by IAET SB RAS squad (guiding by A.N. Savin). Firstly, the site was determined as Neolithic location, but as result of 2010 excavations three Neolithic-middle age cultural horizons were revealed. In the context of the problems connected with investigating of this region (open location character, low stratigraphy situation, high extend of technogenic interruption) the materials of layer 3 are most perspective (high grade of saturation of artifacts, minimal technogenic interruptions). Considering the character of this material occurrence two horizons were contingently distinguished in layer 3. As technical and typological analyses shows in layer 3 of Ku-tarey River Mouth site the full cycle of stone splitting took place to be. Two cultural horizons are differing in tool kit character. The horizon 1 is more saturated of stone tools forms as retouching bladelets, points, oval bifaces, massive forms as polished adzes, chopping axes, bits. While in horizon 2 these forms are practically not presented. In general, stone industry of layer 3 have characteristic of Neolithic - bronze age of North Angara region. Taking into account the stratigraphic situation (layers with "compression" character, technogenic interruption) it is too early to make more detailed conclusions about cultural and chronological interpretation of these materials. In this situation it seems perspective to investigate ceramic complexes, planigrapfic situation, and to compare this materials with other Kutarey sites (Senkin (Siniy) Kamen, Ruchei Povarny, Gora Kutarey) and adjacent territories.
