Between the east and west : The pioneer settlement of Dalarna – Studies of lithic technology and raw material use at the Middle Mesolithic site Orsa 527

In this thesis the pioneer settlement of northern Dalarna is investi­gated by means of a local study of lithic technology and raw material use on the Orsa 527 site in the area. This newly excavated site will be presented, for the first time in completion, in this thesis. The technological traits and raw material distribution on the site, which directly relate to the prehistoric people moving in this area during the Middle Mesolithic, are subsequently put into a larger regional perspective by comparing these results with other Middle Mesolithic sites in northern Dalarna and eastern Norway. Through the theoretical framework of chaîne opératoire and methods, such as dynamical classification of blades, the study of knapping properties of local raw materials and the study of raw material composition on five other sites in the area, questions regarding cultural transition, mobility and contacts can be discussed. The results of this work indicate that both technological and raw material parallels exist between eastern Norway and northern Dalarna during the Middle Mesolithic. This places these areas in a larger cultural sphere that was based on contacts and mobility during the pioneer settlement of the area
