Geological Origins and Coastal Formation

Yyteri’s vast sandy shores, stretching over six kilometers along the Gulf of Bothnia, are the product of millennia of post-glacial rebound and wind-driven aeolian processes. Following the retreat of the Ice Age ice sheet around 10,000 years ago, land uplift gradually exposed the ancient seabed. Over time, prevailing westerly winds shaped the fine quartz sand into towering dunes, reaching heights of up to 20 meters. These dunes, known locally as “ribbskar,” form a dynamic landscape that continues to shift seasonally, offering a living laboratory for coastal geomorphologists and nature enthusiasts alike.
