The Odsherred Peninsula landscape, situated about 100 kilometres from Denmark, was formed only 17,000 years ago during the latter part of the Weichselian era. The Odsherred arches are key localities to understanding the principles of glacial landscape formations from this period. They are also a classic geomorphological example of glacial depressions, end moraines and melt-water flood plains. The glacial series of Odsherred, with its variety of distinct shapes, is surrounded by the sea to the east, north and west. The Geopark also features active, ongoing postglacial coastal processes like lagoon formation, bogs, and sand migration. Today, the area is a leading Danish holiday destination.
