. It was featured on the reverse of the 50 krooni note of 1928 and on the 100 krooni note of 1992. The Baltic Klint is active landform showing some retreat in the present. However it is not known to which degree the Baltic Klint originated in postglacial time or if it evolved from cliff-like forms sculpted by the Fennoscandian Ice Sheet. In Gotland 20th century cliff retreat rates have been estimated at 0.15 to 0.78 cm/year. Retreat of the Baltic Klint in

has widened shore platforms.

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.
