Journal of Nordic Archaeological Science 15, pp. 25–38 (2005) Humanizing of north Ostrobotnian landscapes during the 4th and 3rd millennia Milton Núñez*1 & Jari Okkonen1 *Corresponding author ([email protected]) 1Archaeology Laboratory, PB1000, FIN-90014 University of Oulu, Finland This paper deals with social and cultural developments in North Ostrobotnia during the 4th and 3rd millennia . It links a series of features, both previ- ously known and newly observed, that have been hitherto studied and consid- ered separately. Here they are regarded not only as being contemporaneous and related to each other, but also as an integral part of a trend of increasing social complexity that took place in North Ostrobotnia in the 4th and 3rd millennia (cal). The effect of these developments to North Ostrobotnian landscapes is also discussed. Keywords: asbestos pottery, cairns, maritime hunters, megastructures, semisubterranean house clusters, social complexity Environmental and cultural setting Although Finland lies between the 60th and 70th paral- lels (Fig. 1), the maritime influence of 3500 km of coast- line makes its climate milder than what would be ex- pected from such latitudes. Ostrobotnia falls within the taiga or boreal coniferous zone. The taiga holds adequate though seasonally distributed resources, but in coastal Ostrobotnia productivity would be even higher due to the maritime resources. Local environments have changed considerably through the past 10000 years, and a powerful force shaping Ostrobotnian landscape has been the isostatic rebound. Right after deglaciation, around 8000–7500 cal , the local shore regression reached rates of 10 m/century. Although the uplift rate has been slowing down since then, Ostrobotnia still rises at the impressive rate of 80–90 cm per century. In coastal areas the uplift causes the displacement of the shoreline with a substantial increase of dry land surface and, moreover, the never-ending environmental se- quences of seabottom-skerry-island-peninsula-hill or sea-bay-lake-bog; in other words, the gradual and con- tinuous transformation of coastal environments to in- Figure 1.
