Two high-resolution pollen and charcoal analyses were constructed from sediments obtained from a small bay in eastern Finland in order to gain information on human activity during the Neolithic Stone Age, 5200-1800 BC. We used measurements of loss on ignition (LOI), magnetic susceptibility, and geochemical analyses to describe the sedimentological characteristics. Palaeomagnetic dating and measurements of Cs-137 activity were supported by C14 datings. The analyses revealed human activity between 4400 and 3200 BC, which is synchronous with archaeological cultures defined through different stages of Comb Ware pottery types and Middle Neolithic pottery types with asbestos as a primary temper. Direct evidence of Hordeum cultivation was dated to 4040-3930 cal BC. According to the pollen data, more significant effort was put into the production of fibres from hemp than the actual cultivation of food.
