During the ice age, much of today's coast was below sea level but when the ice melted, the island itself was raised leaving this part of Bornholm's coast some 20 meters above sea level.
Under istiden lå det meste af kysten under havoverfladen, men da isen forsvandt hævede øen sig, og denne del af den bornholmske kyst ligger i dag ca. 20 meter over havet.
