IJsselmeer (Lake Yssel) is an artificial lake in the central Netherlands bordering the provinces of Flevoland, North Holland and Friesland, with an average depth of 5 to 6 m. During a period of severe frost huge parts of this lake freeze up and navigation is hindered. Icebreakers have to secure the navigational routes. After the frost period often in combination with increasing wind force this ice field breaks in to ice plates. Due the very high forces these ice plates drift to the coast, pieces of ice override each other and are causing a piling up of these ice plates. The photo's in this gallery are taken at the coast of the Frisian village Hindeloopen.
