Förden and East Jutland Fjorde
The eastern coast of the Jutland Peninsula, consisting of Danish Jutland and German Schleswig-Holstein features a type of narrow bay called Förde (plural: ''Förden'') in German and fjord (plural ''fjorde'') in Danish. These bays are of glacial origin, but the glacial mechanics were different from those of Norwegian Fjords and also from those of Swedish and Finnish Fjards.
The words ''Förde'', ''fjord'' and ''fjard'' are of the same origin as the English word ''firth''.
== Geology ==
When the area of the present Baltic Sea was covered by a huge ice sheet during the Weichselian glaciation, about 20,000 to 70,000 years before present, the edge of the ice moved on land as tongues of glaciers; these carved out channels. When the ice retreated it created a large lake. The water level rose and the channels were filled by water. The material removed formed moraine hills near the sides and ends of the channels.
Some of these Förden and fjorde are believed not to have been carved out by the ice directly, but to have been washed out by flows of water below the ice (tunnel valleys).
