It is an
Old Drift landscape, characterised by the sandy depositions of the
Ice Age. In the depressions between the raised flats are
wet meadows and, where drainage is poor,
bogs. Geest lands are made up of
moraines and
sandurs. They are almost always next to flat
marshlands, the geest being higher and better protected against flood but, compared to the marsh, with poor soil for agriculture. Where the geest borders the sea directly, sand
cliffs exist. The oldest settlements in Northern Germany and Denmark lie on geest, since it provided better protection against
storm floods. Many important towns are on the boundary between geest and marshland where people could enjoy the flood-protection of the geest but still use the much more fertile soil in the marsh. == Geography ==
