<P> Finnish Lakeland or Finnish lake district (Finnish: Järvi - Suomi, "Lake Finland", Swedish: Insjöfinland) is the largest of the four landscape regions into which the geography of Finland is divided . </P> <P> The hilly, forest - covered landscape of the lake plateau is dominated by drumlins and by long sinuous eskers . Both are glacial remnants after the continental glaciers that scoured and gouged the country's surface receded about 10,000 years ago . </P> <P> The lake basins of the lakeland originate from the joint work of weathering and erosion of fractures in the bedrock . The erosion that made the depressions occurred before and during the Quaternary ice ages . Erosion along fractures has produced linear inlets among the lakes . </P> <P> The district occupies most of the central and East Finland and is bounded to the south by the Salpausselkä Ridges . These ridges are terminal moraines, which trap networks of thousands of lakes separated by hilly forested countryside . </P>
