epoch. As waves batter against limestone cliffs, pre-existing vertical fractures begin to erode and widen. Eventually this leads to the formation of caves that merge with the remaining central rockmass, becoming a rauk. Areas with particularly high concentrations of rauks are Fårö in northern Gotland and Byrum in northwestern Öland. While some rauks occur next to, or as part of cliffs, some have a more tenuous relation to the cliff and some lack a relation altogether.
