Digerhuvud is Sweden’s largest continuous seastack area.
The seastack-area – called raukområde – has a length of about 3.5 km and consists of several hundred rauks, extends along the beach from Släthällar in the southwest to Helgumannen’s fishing village in the northeast.
During the Silurian period (444 – 416 million years ago), Sweden was quite close to the equator, which has resulted in the remains of several large reefs in the Silurian bedrock on Gotland. The bedrock on Gotland testifies to the deposition of sediments (which then formed the calcareous bedrock) into a shallow tropical sea.
The mighty seastack have been formed by erosion – wind, water, waves, gravitational movements and living organisms.
The seastacks ranges in height from a few meters up to 8 meters. Some of the seastacks stand a bit out in the water and are still processed by the waves of the sea. Inside the rauk field is a low cliff, and within this is spread a field of up to 200 meters wide pebbles that almost completely lacks vegetation. Even further in, a low-growth forest of wind-swept beach pines takes over.
It´s a magical nature that meets you while driving or cykling along the coast.
